Managing Serviceguard Eighteenth Edition, September 2010

Guidelines for Non-Rolling Upgrade
Do a non-rolling upgrade if:
• Your cluster does not meet the requirements for rolling upgrade as specified in
the Release Notes for the target version of Serviceguard; or
• The limitations imposed by rolling upgrades make it impractical for you to do a
rolling upgrade (see “Limitations of Rolling Upgrades ” (page 451)); or
• For some other reason you need or prefer to bring the cluster down before
performing the upgrade.
Migrating Cluster Lock PV Device File Names
If you use cluster lock volumes, and you have decided to migrate the device file names
used by the cluster nodes to the HP-UX 11i v3 agile addressing scheme or to cDSFs
(see “About Device File Names (Device Special Files)” (page 106) and “About
Cluster-wide Device Special Files (cDSFs)” (page 135)), use the procedures under
“Updating the Cluster Lock Configuration” (page 364).
Other Considerations
See also “Keeping Kernels Consistent” and “Migrating cmclnodelist entries from
A.11.15 or earlier” (page 453).
Performing a Non-Rolling Upgrade
Limitations of Non-Rolling Upgrades
CAUTION: Stricter limitations apply to an upgrade to A.11.19; do not proceed with
an upgrade to A.11.19 until you have read and understood the Special Considerations
for Upgrade to Serviceguard A.11.19 (page 447).
The following limitations apply to non-rolling upgrades:
• Binary configuration files may be incompatible between releases of Serviceguard.
Do not manually copy configuration files between nodes.
• You must halt the entire cluster before performing a non-rolling upgrade.
Steps for Non-Rolling Upgrades
Use the following steps for a non-rolling software upgrade:
1. Halt all nodes in the cluster:
cmhaltcl -f
2. If necessary, upgrade all the nodes in the cluster to the new HP-UX release. (See
Step 3 under “Running the Rolling Upgrade” (page 452) for more information.)
3. Upgrade all the nodes in the cluster to the new Serviceguard release. (See Step 3
under “Running the Rolling Upgrade” (page 452) for more information.)
