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

1) Use the cfsmgr command to determine which cluster member is currently serving
the root file system. For example:
# cfsmgr -v -a server /
Domain or filesystem name = /
Server Name = polishham
Server Status : OK
2) Relocate the root (/) file system to the lead member. For example:
# cfsmgr -h polishham -r -a SERVER=provolone /
b. Verify that the lead member can serve applications to clients. Make sure that the lead
member can serve all important applications that the cluster makes available to its
clients.
You decide how and what to test. We suggest that you thoroughly exercise critical
applications and satisfy yourself that the lead member can serve these applications to
clients before continuing the roll. For example:
• Manually relocate CAA services to the lead member. For example, to relocate the
application resource named cluster_lockd to lead member provolone:
# caa_relocate cluster_lockd -c provolone
• Temporarily modify the default cluster alias selection priority attribute, selp, to
force the lead member to serve all client requests directed to that alias. For example:
# cluamgr -a alias=DEFAULTALIAS,selp=100
The lead member is now the end recipient for all connection requests and packets
addressed to the default cluster alias.
From another member or from an outside client, use services such as telnet and
ftp to verify that the lead member can handle alias traffic. Test client access to all
important services that the cluster provides.
When you are satisfied, reset the alias attributes on the lead member to their original
values.
7. Perform the postinstall stage (“Postinstall Stage”).
On the lead member, run:
# clu_upgrade postinstall
8. Perform the roll stage (“Roll Stage”).
Roll the members of the cluster that have not already rolled.
1
You can roll multiple members simultaneously (parallel roll), subject to the restriction that
the number of members not being rolled (plus the quorum disk, if one is configured) is
sufficient to maintain cluster quorum.
To roll a member, do the following:
a. Halt the member system and boot it to single-user mode. For example:
# shutdown -h now
>>> boot -fl s
b. When the system reaches single-user mode, run the following commands:
# init s
# bcheckrc
# lmf reset
1. The lead member was rolled during the install stage. Therefore, you do not perform the roll stage on the lead member.
