How to Upgrade the Solaris Operating Environment

Perform this procedure on each node in the cluster to upgrade or prepare the Solaris operating environment to support Sun Cluster 3.0 software.

1. Become superuser on the cluster node.

2. If your volume manager is Solstice DiskSuite and you are using mediators, unconfigure mediators.

   1. Run the following command to verify that no mediator data problems exist.

      # medstat -s setname

      -s setname

      Specifies the diskset name

      If the value in the Status field is Bad, repair the affected mediator host by following the procedure "How to Fix Bad Mediator Data".

      See the medstat(1M) man page for more information.

   2. List all mediators.

      Use this information to determine which node, if any, has ownership of the diskset from which you will remove mediators.

      # metaset -s setname

      Save this information for when you restore the mediators during the procedure "How to Upgrade Cluster Software Packages".

   3. If no node has ownership, take ownership of the diskset.

      # metaset -s setname -t

      -t

      Takes ownership of the diskset

   4. Unconfigure all mediators.

      # metaset -s setname -d -m mediator_host_list

      -s setname

      Specifies the diskset name

      -d

      Deletes from the diskset

      -m mediator_host_list

      Specifies the name of the node to remove as a mediator host for the diskset

      Refer to the mediator(7) man page for further information about mediator-specific options to the metaset command.

   5. Remove the mediator software.

      # pkgrm SUNWmdm

3. Does your configuration currently run Solaris 8 software?

   • If no, go to Step 4.

   • If yes,

   1. Create a file system of at least 100 Mbytes and set its mount point as /globaldevices.

      ---

      Note -

      The /globaldevices file system is necessary for Sun Cluster 3.0 software installation to succeed.

      ---

   2. Reallocate space in other partitions as needed to support Sun Cluster 3.0 software.

      Refer to "System Disk Partitions" for guidelines.

   3. Go to Step 6.

4. Determine which procedure to use to upgrade to Solaris 8 software.

   Volume Manager	Procedure to Use	For Instructions, Go To ...
   Solstice DiskSuite	Upgrading both Solaris and Solstice DiskSuite software	Solstice DiskSuite installation documentation
   VxVM	Performing a standard Solaris software installation	Solaris 8 installation documentation

5. Upgrade to Solaris 8 software, following the procedure you selected in Step 4.

   During installation, make the following changes to the root disk partitioning scheme.

   • Create a file system of at least 100 Mbytes and set its mount point as /globaldevices. The /globaldevices file system is necessary for Sun Cluster 3.0 software installation to succeed.

   • Reallocate space in other partitions as needed to support Sun Cluster 3.0 software.

   Refer to "System Disk Partitions" for partitioning guidelines.

   Note -

   The Solaris interface groups feature is disabled by default during Solaris software installation. Interface groups are not supported in a Sun Cluster configuration and should not be enabled. Refer to the ifconfig(1M) man page for more information about Solaris interface groups.

   ---

6. Install any Solaris software patches.

   Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.

7. Install any hardware-related patches.

   Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.

8. For Solstice DiskSuite software, install any Solstice DiskSuite software patches.

   Refer to Sun Cluster 3.0 Release Notes for the location of patches and installation instructions.

Example--Unconfiguring Mediators

The following example shows the mediator host phys-schost-1 unconfigured from the Solstice DiskSuite diskset schost-1 before the upgrade to Solaris 8 software.

(Check mediator status:)
# medstat -s schost-1
 
(List all mediators:)
# metaset -s schost-1
 
(Unconfigure the mediator:)
# metaset -s schost-1 -d -m phys-schost-1
 
(Remove mediator software:)
# pkgrm SUNWmdm
 
(Begin software upgrade)
