Sun Cluster 3.1 10/03 Software Installation Guide

How to Upgrade the Solaris Operating Environment (Nonrolling)

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.

Note –

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.

  1. Ensure that all steps in How to Prepare the Cluster for Upgrade (Nonrolling) are completed.

  2. Become superuser on the cluster node to upgrade.

  3. 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.

  4. Comment out all entries for globally mounted file systems in the /etc/vfstab file.

    1. Make a record of all entries that are already commented out for later reference.

    2. 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.

  5. Determine which procedure to follow to upgrade the Solaris operating environment.

    Procedure to Use 

    Location of Instructions 

    Solstice DiskSuite/Solaris Volume Manager

    Solaris 8 or Solaris 9 installation documentation 

    VERITAS Volume Manager 

    Upgrading VxVM and Solaris software 

    VERITAS Volume Manager installation documentation 

  6. Upgrade the Solaris software, following the procedure you selected in Step 5.

    Note –

    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

  7. In the /a/etc/vfstab file, uncomment those entries for globally mounted file systems that you commented out in Step 4.

  8. 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

  9. Reboot the node into noncluster mode.

    Include the double dashes (--) in the following command:


    # reboot -- -x

  10. 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.

    Note –

    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.

  11. Upgrade to Sun Cluster 3.1 10/03 software.

    Go to How to Upgrade to Sun Cluster 3.1 10/03 Software (Nonrolling).

    Note –

    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.
