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” on
page 486); 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 (see “About Device File Names (Device Special Files)”
on page 112), use the procedures under “Updating the Cluster Lock
Configuration” on page 361.
Other Considerations
See also “Keeping Kernels Consistent” and “Migrating cmclnodelist
entries from A.11.15 or earlier” on page 488.
