This section provides the following guidelines to upgrade a Sun Cluster configuration:
Observe the following requirements and restrictions when you upgrade to Sun Cluster 3.1 10/03 software:
The cluster must run on or be upgraded to at least Solaris 8 2/02 software, including the most current required patches.
The cluster hardware must be a supported configuration for Sun Cluster 3.1 10/03 software. Contact your Sun representative for information about current supported Sun Cluster configurations.
You must upgrade all software to a version that is supported by Sun Cluster 3.1 10/03 software. For example, you must upgrade a data service that is supported on Sun Cluster 3.0 software but is not supported on Sun Cluster 3.1 10/03 software to the version of that data service that is supported on Sun Cluster 3.1 10/03 software. If the related application is not supported on Sun Cluster 3.1 10/03 software, you must also upgrade that application to a supported release.
The scinstall upgrade utility only upgrades those data services that are provided with Sun Cluster 3.1 10/03 software. You must manually upgrade any custom or third-party data services.
For upgrade from a Sun Cluster 3.0 release, have available the test IP addresses to use with your public network adapters when NAFO groups are converted to Internet Protocol (IP) Network Multipathing groups. The scinstall upgrade utility prompts you for a test IP address for each public network adapter in the cluster. A test IP address must be on the same subnet as the primary IP address for the adapter.
See the IP Network Multipathing Administration Guide (Solaris 8) or System Administration Guide: IP Services (Solaris 9) for information about test IP addresses for IP Network Multipathing groups.
Sun Cluster 3.1 10/03 software supports only nonrolling upgrade from Solaris 8 software to Solaris 9 software.
Sun Cluster 3.1 10/03 software supports direct upgrade only from Sun Cluster 3.x software.
Sun Cluster 3.1 10/03 software does not support any downgrade of Sun Cluster software.
Choose one of the following methods to upgrade your cluster to Sun Cluster 3.1 10/03 software:
Nonrolling upgrade – In a nonrolling upgrade, you shut down the cluster before you upgrade the cluster nodes. You return the cluster to production after all nodes are fully upgraded. You must use the nonrolling-upgrade method if one or more of the following conditions apply:
You are upgrading from Sun Cluster 3.0 software.
You are upgrading from Solaris 8 software to Solaris 9 software.
Any software products you are upgrading, such as applications or databases, require that the same version of the software is running on all cluster nodes.
Rolling upgrade – In a rolling upgrade, you upgrade one node of the cluster at a time. The cluster remains in production with services running on the other nodes. You can use the rolling-upgrade method only if all of the following conditions apply:
You are upgrading from Sun Cluster 3.1 software.
You are upgrading Solaris software only to a Solaris Update release, if at all.
For any applications or databases you must upgrade, the current version of the software can coexist in a running cluster with the upgrade version of that software.
If your cluster configuration meets the requirements to perform a rolling upgrade, you can still choose to perform a nonrolling upgrade instead.
For overview information about planning your Sun Cluster 3.1 10/03 configuration, see Chapter 1, Planning the Sun Cluster Configuration.
Perform the following tasks to perform a nonrolling upgrade from Sun Cluster 3.x software to Sun Cluster 3.1 10/03 software. In a nonrolling upgrade, you shut down the entire cluster before you upgrade the cluster nodes. This procedure also enables you to upgrade the cluster from Solaris 8 software to Solaris 9 software.
To perform a rolling upgrade to Sun Cluster 3.1 10/03 software, instead perform the procedures in Upgrading to Sun Cluster 3.1 10/03 Software (Rolling).

How to Finish Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling) |
Before you upgrade the software, perform the following steps to take the cluster out of production:
Ensure that the configuration meets requirements for upgrade.
Have available the CD-ROMs, documentation, and patches for all software products you are upgrading.
Solaris 8 or Solaris 9 operating environment
Sun Cluster 3.1 10/03 framework
Sun Cluster 3.1 10/03 data services (agents)
Applications that are managed by Sun Cluster 3.1 10/03 data-service agents
VERITAS Volume Manager
See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
(Optional) Install Sun Cluster 3.1 10/03 documentation.
Install the documentation packages on your preferred location, such as an administrative console or a documentation server. See the index.html file at the top level of the Sun Cluster 3.1 10/03 CD-ROM to access installation instructions.
Are you upgrading from Sun Cluster 3.0 software?
If no, proceed to Step 5.
If yes, have available your list of test IP addresses, one for each public network adapter in the cluster.
A test IP address is required for each public network adapter in the cluster, regardless of whether the adapter is the active adapter or the backup adapter in the group. The test IP addresses will be used to reconfigure the adapters to use IP Network Multipathing.
Each test IP address must be on the same subnet as the existing IP address that is used by the public network adapter.
To list the public network adapters on a node, run the following command:
% pnmstat |
See the IP Network Multipathing Administration Guide (Solaris 8) or System Administration Guide: IP Services (Solaris 9) for more information about test IP addresses for IP Network Multipathing.
Notify users that cluster services will be unavailable during upgrade.
Ensure that the cluster is functioning normally.
To view the current status of the cluster, run the following command from any node:
% scstat |
See the scstat(1M) man page for more information.
Search the /var/adm/messages log on the same node for unresolved error messages or warning messages.
Check volume-manager status.
Become superuser on a node of the cluster.
Switch each resource group offline.
# scswitch -F -g resource-group |
Switches a resource group offline
Specifies the name of the resource group to take offline
Disable all resources in the cluster.
The disabling of resources before upgrade prevents the cluster from bringing the resources online automatically if a node is mistakenly rebooted into cluster mode.
If you are upgrading from a Sun Cluster 3.1 release, you can use the scsetup(1M) utility instead of the command line. From the Main Menu, choose Resource Groups, then choose Enable/Disable Resources.
From any node, list all enabled resources in the cluster.
# scrgadm -pv | grep "Res enabled" |
Identify those resources that depend on other resources.
You must disable dependent resources first before you disable the resources that they depend on.
Disable each enabled resource in the cluster.
scswitch -n -j resource |
Disables
Specifies the resource
See the scswitch(1M) man page for more information.
Move each resource group to the unmanaged state.
# scswitch -u -g resource-group |
Moves the specified resource group to the unmanaged state
Specifies the name of the resource group to move into the unmanaged state
Verify that all resources on all nodes are disabled and that all resource groups are in the unmanaged state.
# scstat -g |
Stop all databases that are running on each node of the cluster.
Ensure that all shared data is backed up.
From one node, shut down the cluster.
# scshutdown ok |
See the scshutdown(1M) man page for more information.
Boot each node into noncluster mode.
ok boot -x |
Ensure that each system disk is backed up.
Determine whether to upgrade the Solaris operating environment.
If Sun Cluster 3.1 10/03 software does not support the release of the Solaris environment that you currently run on your cluster, you must upgrade the Solaris software to a supported release. Go to How to Upgrade the Solaris Operating Environment (Nonrolling).
If your cluster configuration already runs on a release of the Solaris environment that supports Sun Cluster 3.1 10/03 software, further Solaris software upgrade is optional.
To upgrade Sun Cluster software, go to How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling).
To upgrade Solaris software, go to How to Upgrade the Solaris Operating Environment (Nonrolling).
See “Supported Products” in Sun Cluster 3.1 10/03 Release Notes for more information.
Perform this procedure on each node in the cluster to upgrade the Solaris operating environment. If the cluster already runs on a version of the Solaris environment that supports Sun Cluster 3.1 10/03 software, this procedure is optional.
The cluster must already run on, or be upgraded to, at least the minimum required level of the Solaris 8 or Solaris 9 environment to support Sun Cluster 3.1 10/03 software. See “Supported Products” in Sun Cluster 3.1 10/03 Release Notes for more information.
Ensure that all steps in How to Prepare the Cluster for Upgrade (Nonrolling) are completed.
Become superuser on the cluster node to upgrade.
Determine whether the following Apache links already exist, and if so, whether the file names contain an uppercase K or S:
/etc/rc0.d/K16apache /etc/rc1.d/K16apache /etc/rc2.d/K16apache /etc/rc3.d/S50apache /etc/rcS.d/K16apache |
If these links already exist and do contain an uppercase K or S in the file name, no further action is necessary for these links.
If these links do not exist, or if these links exist but instead contain a lowercase k or s in the file name, you move aside these links in Step 8.
Comment out all entries for globally mounted file systems in the /etc/vfstab file.
Make a record of all entries that are already commented out for later reference.
Temporarily comment out all entries for globally mounted file systems in the /etc/vfstab file.
Entries for globally mounted file systems contain the global mount option. Comment out these entries to prevent the Solaris upgrade from attempting to mount the global devices.
Determine which procedure to follow to upgrade the Solaris operating environment.

Upgrade the Solaris software, following the procedure you selected in Step 5.
Ignore the instruction to reboot at the end of the Solaris software upgrade process. You must first perform Step 7 and Step 8, then reboot into noncluster mode in Step 9 to complete Solaris software upgrade.
If you are instructed to reboot a node at other times during the upgrade process, always add the -x option to the command. This option ensures that the node reboots into noncluster mode. For example, either of the following two commands boot a node into single-user noncluster mode:
# reboot -- -xs ok boot -xs |
In the /a/etc/vfstab file, uncomment those entries for globally mounted file systems that you commented out in Step 4.
If the Apache links in Step 3 did not already exist or if they contained a lowercase k or s in the file names before you upgraded the Solaris software, move aside the restored Apache links.
Use the following commands to rename the files with a lowercase k or s:
# mv /a/etc/rc0.d/K16apache /a/etc/rc0.d/k16apache # mv /a/etc/rc1.d/K16apache /a/etc/rc1.d/k16apache # mv /a/etc/rc2.d/K16apache /a/etc/rc2.d/k16apache # mv /a/etc/rc3.d/S50apache /a/etc/rc3.d/s50apache # mv /a/etc/rcS.d/K16apache /a/etc/rcS.d/k16apache |
Reboot the node into noncluster mode.
Include the double dashes (--) in the following command:
# reboot -- -x |
Install any required Solaris software patches and hardware-related patches, and download any needed firmware that is contained in the hardware patches.
For Solstice DiskSuite software (Solaris 8), also install any Solstice DiskSuite software patches.
Do not reboot after you add patches. You reboot the node after you upgrade the Sun Cluster software.
See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
Upgrade to Sun Cluster 3.1 10/03 software.
Go to How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling).
To complete upgrade from Solaris 8 to Solaris 9 software, you must also upgrade to the Solaris 9 version of Sun Cluster 3.1 10/03 software, even if the cluster already runs on Sun Cluster 3.1 10/03 software.
This procedure describes how to upgrade the cluster to Sun Cluster 3.1 10/03 software. You must also perform this procedure to complete cluster upgrade from Solaris 8 to Solaris 9 software.
You can perform this procedure on more than one node at the same time.
Ensure that all steps in How to Prepare the Cluster for Upgrade (Nonrolling) are completed.
If you upgraded from Solaris 8 to Solaris 9 software, also ensure that all steps in How to Upgrade the Solaris Operating Environment (Nonrolling) are completed.
Become superuser on a node of the cluster.
Ensure that you have installed all required Solaris software patches and hardware-related patches.
For Solstice DiskSuite software (Solaris 8), also ensure that you have installed all required Solstice DiskSuite software patches.
Insert the Sun Cluster 3.1 10/03 CD-ROM into the CD-ROM drive on the node.
If the Volume Management daemon vold(1M) is running and configured to manage CD-ROM devices, it automatically mounts the CD-ROM on the /cdrom/suncluster_3_1_u1 directory.
Upgrade the node to Sun Cluster 3.1 10/03 software.
Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Tools directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) .
# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_ver/Tools |
Upgrade the cluster framework software.
To upgrade from Sun Cluster 3.0 software, run the following command:
# ./scinstall -u update -S interact -M patchdir=dirname |
Specifies the test IP addresses to use to convert NAFO groups to IP Network Multipathing groups
Specifies that scinstall prompts the user for each test IP address needed
Specifies the path to patch information so that the specified patches can be installed using the scinstall command. If you do not specify a patch-list file, the scinstall command installs all the patches in the directory dirname, including tarred, jarred, and zipped patches.
The -M option is not required. You can use any method you prefer for installing patches.
To upgrade from Sun Cluster 3.1 software, run the following command:
# ./scinstall -u update -M patchdir=dirname |
Specifies the path to patch information so that the specified patches can be installed using the scinstall command. If you do not specify a patch-list file, the scinstall command installs all the patches in the directory dirname, including tarred, jarred, and zipped patches.
The -M option is not required. You can use any method you prefer for installing patches.
See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
If upgrade processing is interrupted, use the scstat(1M) command to ensure that the node is in noncluster mode (Offline), then restart the scinstall command.
# scstat -n -- Cluster Nodes -- Node name Status --------- ------ Cluster node: nodename Offline Cluster node: nodename Offline |
See the scinstall(1M) man page for more information. See the IP Network Multipathing Administration Guide (Solaris 8) or System Administration Guide: IP Services (Solaris 9) for information about test addresses for IP Network Multipathing.
Sun Cluster 3.1 software requires at least version 3.5.1 of Sun Explorer software. Upgrade to Sun Cluster software includes installing Sun Explorer data collector software, to be used in conjunction with the sccheck utility. If another version of Sun Explorer software was already installed before Sun Cluster upgrade, it is replaced by the version that is provided with Sun Cluster software. Options such as user identity and data delivery are preserved, but crontab entries must be manually recreated.
During Sun Cluster upgrade, scinstall might make one or more of the following configuration changes:
Change to the CD-ROM root directory and eject the CD-ROM.
Upgrade software applications that are installed on the cluster.
Ensure that application levels are compatible with the current version of Sun Cluster and Solaris software. See your application documentation for installation instructions. In addition, follow these guidelines to upgrade applications in a Sun Cluster 3.1 10/03 configuration:
If the applications are stored on shared disks, you must master the relevant disk groups and manually mount the relevant file systems before you upgrade the application.
If you are instructed to reboot a node during the upgrade process, always add the -x option to the command. This option ensures that the node reboots into noncluster mode. For example, either of the following two commands boot a node into single-user noncluster mode:
# reboot -- -xs ok boot -xs |
(Optional) Upgrade Sun Cluster data services to the Sun Cluster 3.1 10/03 software versions.
You must upgrade the Sun Cluster HA for Oracle 3.0 64–bit for Solaris 9 data service to the Sun Cluster 3.1 10/03 version. Otherwise, you can continue to use Sun Cluster 3.0 data services after upgrade to Sun Cluster 3.1 10/03 software.
Only those data services that are provided on the Sun Cluster 3.1 Agents CD-ROM are automatically upgraded by scinstall(1M). You must manually upgrade any custom or third-party data services.
Insert the Sun Cluster 3.1 Agents CD-ROM into the CD-ROM drive on the node to upgrade.
Upgrade the data-service software.
# scinstall -u update -s all -d /cdrom/cdrom0 |
Specifies upgrade
Updates all Sun Cluster data services that are installed on the node
If upgrade processing is interrupted, use the scstat(1M) command to ensure that the node is in noncluster mode (Offline), then restart the scinstall command.
# scstat -n -- Cluster Nodes -- Node name Status --------- ------ Cluster node: nodename Offline Cluster node: nodename Offline |
Change to the CD-ROM root directory and eject the CD-ROM.
As needed, manually upgrade any custom data services that are not supplied on the Sun Cluster 3.1 Agents CD-ROM.
Install any Sun Cluster 3.1 10/03 data-service patches.
See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
After all nodes are upgraded, reboot each node into the cluster.
# reboot |
Verify that all upgraded software is at the same version on all upgraded nodes.
On each upgraded node, view the installed levels of Sun Cluster software.
# scinstall -pv |
From one node, verify that all upgraded cluster nodes are running in cluster mode (Online).
# scstat -n |
See the scstat(1M) man page for more information about displaying cluster status.
On each node, run the following command to verify the consistency of the storage configuration:
# scdidadm -c |
Perform a consistency check
Do not proceed to Step 12 until your configuration passes this consistency check. Failure to do so might result in errors in device identification and cause data corruption.
The following table lists the possible output from the scdidadm -c command and the action you must take, if any.
Example Message |
Action to Take |
---|---|
device id for 'phys-schost-1:/dev/rdsk/c1t3d0' does not match physical device's id, device may have been replaced |
Go to Recovering From Storage Configuration Changes During Upgrade and perform the appropriate repair procedure. |
device id for 'phys-schost-1:/dev/rdsk/c0t0d0' needs to be updated, run scdidadm –R to update |
None. You update this device ID in Step 12. |
No output message |
None |
See the scdidadm(1M) man page for more information.
On each node, migrate the Sun Cluster storage database to Solaris 9 device IDs.
# scdidadm -R all |
Perform repair procedures
Specify all devices
On each node, run the following command to verify that storage database migration to Solaris 9 device IDs is successful:
# scdidadm -c |
If the scdidadm command displays a message, return to Step 11 to make further corrections to the storage configuration or the storage database.
If the scdidadm command displays no messages, the device-ID migration is successful. If device-ID migration is verified on all cluster nodes, proceed to Step 14.
If no, proceed to Step 15.
If yes, upgrade all disk groups.
To upgrade a disk group to the highest version supported by the VxVM release you installed, run the following command from the primary node of the disk group:
# vxdg upgrade dgname |
See your VxVM administration documentation for more information about upgrading disk groups.
Do you intend to use Sun Management Center to monitor the cluster?
The following example shows the process of a nonrolling upgrade of a two-node cluster from Sun Cluster 3.0 to Sun Cluster 3.1 10/03 software on the Solaris 8 operating environment. The cluster node names are phys-schost-1 and phys-schost-2.
(On the first node, upgrade framework software from the Sun Cluster 3.1 10/03 CD-ROM) phys-schost-1# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_8/Tools phys-schost-1# ./scinstall -u update -S interact (On the first node, upgrade data services from the Sun Cluster 3.1 Agents CD-ROM) phys-schost-1# ./scinstall -u update -s all -d /cdrom/cdrom0 (On the second node, upgrade framework software from the Sun Cluster 3.1 10/03 CD-ROM) phys-schost-2# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_8/Tools phys-schost-2# ./scinstall -u update -S interact (On the second node, upgrade data services from the Sun Cluster 3.1 Agents CD-ROM) phys-schost-2# ./scinstall -u update -s all -d /cdrom/cdrom0 (Reboot each node into the cluster) phys-schost-1# reboot phys-schost-2# reboot (Verify cluster membership) # scstat -- Cluster Nodes -- Node name Status --------- ------ Cluster node: phys-schost-1 Online Cluster node: phys-schost-2 Online |
Perform the following steps to upgrade to the Sun Cluster 3.1 10/03 module software packages for Sun Management Center on the Sun Management Center server machine and help-server machine.
Ensure that all Sun Management Center core packages are installed on the appropriate machines, as described in your Sun Management Center installation documentation.
This step includes installing Sun Management Center agent packages on each cluster node.
Become superuser on the Sun Management Center server machine.
Insert the Sun Cluster 3.1 10/03 CD-ROM into the CD-ROM drive.
Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Packages directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) .
# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_ver/Packages |
Install the Sun Cluster–module server package SUNWscssv.
# pkgadd -d . SUNWscssv |
Change to the CD-ROM root directory and eject the CD-ROM.
Become superuser on the Sun Management Center help-server machine.
Repeat Step 3 through Step 6 to install the Sun Cluster–module help-server package SUNWscshl.
Finish the upgrade.
Go to How to Finish Upgrading to Sun Cluster 3.1 10/03 Software (Nonrolling).
Perform this procedure to reregister and reversion all resource types that received a new version from the upgrade, then to re-enable resources and bring resource groups back online.
To upgrade future versions of resource types, see “Upgrading a Resource Type” in Sun Cluster 3.1 Data Service 4/03 Planning and Administration Guide.
Ensure that all steps in How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling) are completed.

Go to How to Upgrade to Sun Cluster 3.1 10/03 Software (Rolling).
Perform this procedure to upgrade a node to Sun Cluster 3.1 10/03 software while the remaining cluster nodes are in cluster mode.
Do not use any new features provided in the Sun Cluster 3.1 10/03 software until all nodes of the cluster are upgraded.
Ensure that all steps in How to Prepare the Cluster for Upgrade (Rolling) are completed.
If you upgraded the Solaris operating environment to a Maintenance Update release, also ensure that all steps in How to Upgrade to a Solaris Maintenance Update Release (Rolling) are completed.
Upgrade to Sun Cluster 3.1 10/03 software.
Insert the Sun Cluster 3.1 10/03 CD-ROM into the CD-ROM drive on the node.
If the Volume Management daemon vold(1M) is running and configured to manage CD-ROM devices, it automatically mounts the CD-ROM on the /cdrom/suncluster_3_1_u1 directory.
Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Tools directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) .
# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_ver/Tools |
Install the Sun Cluster 3.1 10/03 software.
Do not use the /usr/cluster/bin/scinstall command that is already installed on the node. You must use the scinstall command on the Sun Cluster 3.1 10/03 CD-ROM.
# ./scinstall -u update -M patchdir=dirname |
Specifies the path to patch information so that the specified patches can be installed using the scinstall command. If you do not specify a patch-list file, the scinstall command installs all the patches in the directory dirname, including tarred, jarred, and zipped patches.
The -M option is not required. You can use any method you prefer for installing patches.
If upgrade processing is interrupted, use the scstat(1M) command to ensure that the node is in noncluster mode (Offline), then restart the scinstall command.
# scstat -n -- Cluster Nodes -- Node name Status --------- ------ Cluster node: nodename Offline Cluster node: nodename Offline |
See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.
See the scinstall(1M) man page for more information.
Sun Cluster 3.1 software requires at least version 3.5.1 of Sun Explorer software. Upgrade to Sun Cluster software includes installing Sun Explorer data collector software, to be used in conjunction with the sccheck utility. If another version of Sun Explorer software was already installed before Sun Cluster upgrade, it is replaced by the version that is provided with Sun Cluster software. Options such as user identity and data delivery are preserved, but crontab entries must be manually recreated.
Change to the CD-ROM root directory and eject the CD-ROM.
Install any Sun Cluster 3.1 10/03 software patches.
Do you intend to upgrade any data services?
Upgrade applications as needed.
Do not upgrade an application if the newer version cannot coexist in the cluster with the older version.
Follow the instructions that are provided in your third-party documentation.
(Optional) For each node on which data services are installed, upgrade to the Sun Cluster 3.1 10/03 data-service update software.
You must upgrade the Sun Cluster HA for Oracle 3.0 64–bit for Solaris 9 data service to the Sun Cluster 3.1 10/03 version. Otherwise, you can continue to use Sun Cluster 3.0 data services after upgrade to Sun Cluster 3.1 10/03 software.
Insert the Sun Cluster 3.1 Agents CD-ROM into the CD-ROM drive on the node.
Install the Sun Cluster 3.1 10/03 data-service–update patches.
Use one of the following methods:
To upgrade one or more specified data services, type the following command.
# scinstall -u update -s srvc[,srvc,…] -d cdrom-image |
Upgrades a cluster node to a later Sun Cluster software release
Upgrades the specified data service
Specifies an alternate directory location for the CD-ROM image
To upgrade all data services present on the node, type the following command.
# scinstall -u update -s all -d cdrom-image |
Upgrades all data services
This command assumes that updates for all installed data services exist on the update release. If an update for a particular data service does not exist in the update release, that data service is not upgraded.
Change to the CD-ROM root directory and eject the CD-ROM.
Install any Sun Cluster 3.1 10/03 data-service software patches.
Verify that each data-service update patch is installed successfully.
View the upgrade log file that is referenced at the end of the upgrade output messages.
Reboot the node into the cluster.
# reboot |
Run the following command on the upgraded node to verify that Sun Cluster 3.1 10/03 software is installed successfully.
# scinstall -pv |
From any node, verify the status of the cluster configuration.
% scstat % scrgadm -pv[v] |
Output should be the same as for Step 4 in How to Prepare the Cluster for Upgrade (Rolling).
Do you have another node to upgrade?
If yes, return to How to Prepare the Cluster for Upgrade (Rolling) and repeat all upgrade procedures on the next node to upgrade.
If no, go to How to Finish Upgrading to Sun Cluster 3.1 10/03 Software (Rolling).
Ensure that all upgrade procedures are completed for all cluster nodes that you are upgrading.
Are you using Sun Management Center to monitor your Sun Cluster configuration?
If no, proceed to Step 3.
If yes, perform the following steps
Ensure that all Sun Management Center core packages are installed on the appropriate machines, as described in your Sun Management Center installation documentation.
This step includes installing Sun Management Center agent packages on each cluster node.
Become superuser on the Sun Management Center server machine.
Insert the Sun Cluster 3.1 10/03 CD-ROM into the CD-ROM drive.
Change to the /cdrom/suncluster_3_1/SunCluster_3.1/Sol_ver/Packages directory, where ver is 8 (for Solaris 8) or 9 (for Solaris 9) .
# cd /cdrom/suncluster_3_1_u1/SunCluster_3.1/Sol_ver/Packages |
Install the Sun Cluster–module server package SUNWscssv.
# pkgadd -d . SUNWscssv |
Change to the CD-ROM root directory and eject the CD-ROM.
Become superuser on the Sun Management Center help-server machine.
Repeat Step e through Step g to install the Sun Cluster–module help-server package SUNWscshl.
Reregister and re-version all resource types that received a new version from the upgrade, then re-enable resources and bring resource groups back online.
From any node, start the scsetup(1M) utility.
# scsetup |
To work with resource groups, type 2 (Resource groups).
To register resource types, type 4 (Resource type registration).
Type yes when prompted to continue.
Type 1 (Register all resource types which are not yet registered).
The scsetup utility displays all resource types that are not registered.
Type yes to continue to register these resource types.
Type 8 (Change properties of a resource).
Type yes to continue.
Type 3 (Manage resource versioning).
Type yes to continue.
Type 1 (Show versioning status).
The scsetup utility displays which resources you can upgrade to new versions of the same resource type, and the state that the resource should be in before the upgrade can begin.
Type yes to continue.
Type 4 (Re-version all eligible resources).
Type yes to continue when prompted.
Return to the Resource Group Menu.
Type 6 (Enable/Disable a resource).
Type yes to continue when prompted.
Select a resource to enable and follow the prompts.
Repeat Step k for each disabled resource.

Follow the prompts to bring each resource group online.
Exit the scsetup utility.
Type q to back out of each submenu, or press Ctrl-C.
Restart any applications.
Follow the instructions that are provided in your third-party documentation.
The cluster upgrade is complete.
This section provides the following repair procedures to follow if changes were inadvertently made to the storage configuration during upgrade:
Any changes to the storage topology, including running Sun Cluster commands, should be completed before you upgrade the cluster to Solaris 9 software. If, however, changes were made to the storage topology during the upgrade, perform the following procedure. This procedure ensures that the new storage configuration is correct and that existing storage that was not reconfigured is not mistakenly altered.
Ensure that the storage topology is correct.
Check whether the devices that were flagged as possibly being replaced map to devices that actually were replaced. If the devices were not replaced, check for and correct possible accidental configuration changes, such as incorrect cabling.
Become superuser on a node that is attached to the unverified device.
Manually update the unverified device.
# scdidadm -R device |
Performs repair procedures on the specified device
See the scdidadm(1M) man page for more information.
Update the DID driver.
# scdidadm -ui # scdidadm -r |
Loads the device ID configuration table into the kernel
Initializes the DID driver
Reconfigures the database
Repeat Step 2 through Step 4 on all other nodes that are attached to the unverified device.
Return to the remaining upgrade tasks.
For nonrolling upgrade, go to Step 11 in How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling).
For rolling upgrade, go to Step 4 in How to Prepare the Cluster for Upgrade (Rolling).
If accidental changes are made to the storage cabling during the upgrade, perform the following procedure to change the storage configuration back to the correct state.
This procedure assumes that no physical storage was actually changed. If physical or logical storage devices were changed or replaced, instead follow procedures in How to Handle Storage Reconfiguration During an Upgrade.
Change the storage topology back to its original configuration.
Check the configuration of the devices that were flagged as possibly being replaced, including the cabling.
As superuser, update the DID driver on each node of the cluster.
# scdidadm -ui # scdidadm -r |
Loads the device–ID configuration table into the kernel
Initializes the DID driver
Reconfigures the database
See the scdidadm(1M) man page for more information.
Did the scdidadm command return any error messages in Step 2?
Return to the remaining upgrade tasks.
For nonrolling upgrade, go to Step 11 in How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling).
