Sun Cluster 3.0 U1 Installation Guide

How to Finish Upgrading Cluster Software

This procedure finishes the scinstall(1M) upgrade process begun in "How to Upgrade Cluster Software Packages". Perform these steps on each node of the cluster.

  1. Become superuser on each node of the cluster.

  2. Choose a shared disk to be the quorum device.

    You can use any disk shared by both nodes as a quorum device. From either node, use the scdidadm(1M) command to determine the shared disk's device ID (DID) name. You specify this device name in Step 5, in the -q globaldev=DIDname option to scinstall.


    # scdidadm -L

  3. If your volume manager is VxVM, reinstall and configure the VxVM software on each node of the cluster, including any patches.

    Follow the procedures in "Installing and Configuring VxVM Software".

    Note -

    If you must reboot the first-installed node, first shut down the cluster by using the scshutdown(1M) command, then reboot. Do not reboot the first-installed node of the cluster until after the cluster is shut down.

    Until cluster install mode is disabled, only the first-installed node, which established the cluster, has a quorum vote. In an established cluster that is still in install mode, if the cluster is not shut down before the first-installed node is rebooted, the remaining cluster nodes cannot obtain quorum and the entire cluster shuts down.

    To determine which is the first-installed node, view quorum vote assignments by using the scconf -p command. The only node that has a quorum vote is the first-installed node.

    After you perform Step 7, quorum votes are assigned and this reboot restriction is no longer necessary.

  4. Insert the Sun Cluster 3.0 Agents 7/01 CD-ROM into the CD-ROM drive on a node.

    This step assumes that the volume daemon vold(1M) is running and configured to manage CD-ROM devices.

  5. Finish the cluster software upgrade on that node. 


    # scinstall -u finish -q globaldev=DIDname \
-d /cdrom/scdataservices_3_0 -s srvc[,srvc]
    -q globaldev=DIDname

    Specifies the device ID (DID) name of the quorum device

    -d /cdrom/scdataservices_3_0

    Specifies the directory location of the CD-ROM image

    -s srvc

    Specifies the name of the data service to configure

    Note -

    An error message similar to the following might be generated. You can safely ignore it.


    ** Installing Sun Cluster - Highly Available NFS Server **
Skipping "SUNWscnfs" - already installed

  6. Eject the CD-ROM.

  7. Repeat Step 4 through Step 6 on the other node.

    When completed on both nodes, cluster install mode is disabled and all quorum votes are assigned.

  8. If your volume manager is Solstice DiskSuite, from either node bring pre-existing disk device groups online.


    # scswitch -z -D disk-device-group -h node
    -z

    Performs the switch

    -D disk-device-group

    Specifies the name of the disk device group, which for Solstice DiskSuite software is the same as the diskset name

    -h node

    Specifies the name of the cluster node that serves as the primary of the disk device group

  9. From either node, bring pre-existing data service resource groups online.

    At this point, Sun Cluster 2.2 logical hosts are converted to Sun Cluster 3.0 U1 resource groups, and the names of logical hosts are appended with the suffix -lh. For example, a logical host named lhost-1 is upgraded to a resource group named lhost-1-lh. Use these converted resource group names in the following command.


    # scswitch -z -g resource-group -h node
    -g resource-group

    Specifies the name of the resource group to bring online

    You can use the scrgadm -p command to display a list of all resource types and resource groups in the cluster. The scrgadm -pv command displays this list with more detail.

  10. If you are using Sun Management Center to monitor your Sun Cluster configuration, install the Sun Cluster module for Sun Management Center.

    1. Ensure that you are using the most recent version of Sun Management Center.

      See your Sun Management Center documentation for installation or upgrade procedures.

    2. Follow guidelines and procedures in "Installation Requirements for Sun Cluster Monitoring" to install the Sun Cluster module packages.

  11. Verify that all nodes have joined the cluster.

    Go to "How to Verify Cluster Membership".

Example--Upgrading From Sun Cluster 2.2 to Sun Cluster 3.0 U1 Software - Finish Process

The following example shows the finish process of upgrading a two-node cluster upgraded from Sun Cluster 2.2 to Sun Cluster 3.0 U1 software. The cluster node names are phys-schost-1 and phys-schost-2, the device group names are dg-schost-1 and dg-schost-2, and the data service resource group names are lh-schost-1 and lh-schost-2.


(Determine the DID of the shared quorum device)
phys-schost-1# scdidadm -L
 
(Finish upgrade on each node)
phys-schost-1# scinstall -u finish -q globaldev=d1 \
-d /cdrom/suncluster_3_0u1 -s nfs
phys-schost-2# scinstall -u finish -q globaldev=d1 \
-d /cdrom/suncluster_3_0u1 -s nfs
 
(Bring device groups and data service resource groups
on each node online)
phys-schost-1# scswitch -z -D dg-schost-1 -h phys-schost-1
phys-schost-1# scswitch -z -g lh-schost-1 -h phys-schost-1
phys-schost-1# scswitch -z -D dg-schost-2 -h phys-schost-2 
phys-schost-1# scswitch -z -g lh-schost-2 -h phys-schost-2
