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

Caution:
If, for any reason, during an upgrade you need to create tagged files for a layered product,
see “Tagged Files”.
• Sets the sysconfigtab variable rolls_ver_lookup=1 on all members except the lead
member. When rolls_ver_lookup=1, a member uses tagged files. As a result, the lead
member can upgrade while the remaining members run on the .Old.. files from the current
release.
• Prompts you to reboot all cluster members except the lead member. When the setup
command completes, reboot these members one at a time so that the cluster can maintain
quorum. This reboot is required for each member that will use tagged files in the
mixed-version cluster. When the reboots complete, all members except the lead member are
running on tagged files.
Preinstall Stage
Run LevelWhere RunCommand
multi-user modelead member
clu_upgrade preinstall
The purpose of the preinstall stage is to verify that the cluster is ready for the lead member to
run one or more of the installupdate, dupatch, or nhd_install commands.
The clu_upgrade preinstall command performs the following tasks:
• Verifies that the command is being run on the lead member, that the lead member is not
running on tagged files, and that any other cluster members that are up are running on
tagged files.
• (Optional) Verifies that tagged files are present, that they match their product's inventory
files, and that each tagged file's AdvFS property is set correctly. (This process can take a
while, but not as long as it does to create the tagged files in the setup stage. Table 4-2 “Time
Estimates for Rolling Upgrade Stages” provides time estimates for each stage.)
• Makes on-disk backup copies of the lead member's member-specific files.

If your current cluster is running TruCluster software Version 5.1B or Version 5.1A, you can
perform one of the tasks or combinations of tasks listed in Table 4-1 “Rolling Upgrade Tasks
Supported by Version 5.1A and Version 5.1B”.
The install stage starts when the clu_upgrade preinstall command completes, and continues
until you run the clu_upgrade postinstall command.
