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

Note:
If you run clu_upgrade status after running installupdate, clu_upgrade displays a
message indicating that the install stage is complete. However, the install stage is not really
complete until you run the clu_upgrade postinstall command.
The lead member must be in single-user mode to run the installupdate command or the
nhd_install command; single-user mode is recommended for the dupatch command. When
taking the system to single-user mode, you must halt the system and then boot it to single-user
mode.
When the system is in single-user mode, run the init s, bcheckrc, and lmf reset commands
before you run the installupdate, dupatch, or nhd_install commands.
Notes:
You can run the dupatch command multiple times in order to install multiple patches. Doing
so may make isolating problems difficult if any arise after the patch process is completed and
the cluster is in use.
During the install stage, you cannot run a dupatch command followed by an installupdate
command. To patch the current software before you perform a rolling upgrade, you must perform
two complete rolling upgrade operations: one to patch the current software, and one to perform
the update installation.
If an NHD installation is part of a rolling upgrade that includes an update installation, you do
not have to manually run nhd_install; the installupdate command will install the NHD
kit. Otherwise, use the nhd_install command copied by clu_upgrade during the setup
stage: /var/adm/update/NHDKit/nhd_install.
Postinstall Stage
Run LevelWhere RunCommand
multi-user modelead member
clu_upgrade postinstall
The postinstall stage verifies that the lead member has completed an update installation, a patch,
or an NHD installation. If an update installation was performed, clu_upgrade postinstall
verifies that the lead member has rolled to the new version of the base operating system.
Roll Stage
Run LevelWhere RunCommand

clu_upgrade roll
The lead member was upgraded in the install stage. The remaining members are upgraded in
the roll stage.
In many cluster configurations, you can roll multiple members in parallel and shorten the time
required to upgrade the cluster. The number of members rolled in parallel is limited only by the
requirement that the members not being rolled (plus the quorum disk, if one is configured) have
sufficient votes to maintain quorum. Parallel rolls can be performed only after the lead member
is rolled.
