HP Tru64 UNIX Version 5.1B-2 and Higher Patch Kit Installation Instructions (March 2009)

d. To determine whether the cluster is ready for an upgrade, run the clu_upgrade -v
check setup lead_memberid command on any cluster member. For example:
# clu_upgrade -v check setup 2
If a file system needs more free space, use AdvFS utilities such as addvol to add volumes
to domains as needed. For disk space requirements, see “Preparation Stage”. For
information on managing AdvFS domains, see the Tru64 UNIX AdvFS Administration
manual.
e. Verify that each system's firmware will support the new software. Update firmware as
needed before starting the rolling upgrade.
2. Perform the setup stage (“Setup Stage”).
Notes:
If your current cluster is at Version 5.1A or later and if you plan to upgrade the base operating
system and cluster software during the install stage, mount the device or directory that
contains the new TruCluster software kit before running clu_upgrade setup. The setup
command will copy the kit to the /var/adm/update/TruClusterKit directory.
If your current cluster is at Version 5.1A or later and if you plan to install an NHD kit during
the install stage, mount the device or directory that contains the new NHD kit before running
clu_upgrade setup. The setup command will copy the kit to the /var/adm/update/
NHDKit directory.
On any member, run the clu_upgrade setup lead_memberid command. For example:
# clu_upgrade setup 2
“Setup Stage” shows the menu displayed by the clu_upgrade command.
When the setup stage is completed, clu_upgrade prompts you to reboot all cluster members
except the lead member.
3. One at a time, reboot all cluster members except the lead member. Do not start the preinstall
stage until these members are either rebooted or halted.
4. Perform the preinstall stage (“Preinstall Stage”).
On the lead member, run the following command:
# clu_upgrade preinstall
If your current cluster is at Version 5.1A or later, the preinstall command gives you the
option of verifying or not verifying the existence of the tagged files created during the setup
stage.
• If you have just completed the setup stage and have done nothing to cause the deletion
any of the tagged files, you can skip this test.
• If you completed the setup stage a while ago and are not sure what to do, let
preinstall test the correctness of the tagged files.
5. Perform the install stage (“Install Stage”).
