HP Serviceguard Toolkit for Integrity Virtual Servers User Guide

NOTE: This is a requirement of HP Serviceguard A.11.20.
2. To disable application monitoring (that is, comment out cmappmgr calls), edit all the packages.
3. Reapply the packages.
Application monitoring is not used while reapplying, therefore, these VM guests can now be
live-migrated.
NOTE: Check and ensure that the various cmappmgr services are stopped.
4. Live-migrate all the VM guests from one node and upgrade the HP Serviceguard on that node.
After a node is upgraded, the other HP Integrity VM guest packages can be live-migrated to
this node.
NOTE: Packages can be moved if there are issues with live migration, but the services stop
and cannot be restarted until the last step is performed.
5. Live-migrate the packages from each node that must be upgraded, and then upgrade that
node.
6. Optional: Live-migrate the packages between nodes to balance the cluster and VM guests.
7. Update cmappserver in every VM guest
8. For each HP Integrity VM guest package that used guest monitoring, do the following:
a. Halt the package.
b. Re-enable all of the cmappmgr calls in each package.
c. Reapply the package.
d. Start the package.
NOTE: The applications on the VM guests are not available for a short period, during the live
migration and between halting and restarting the package.
Process 2: In this process VM guests can reboot rather than use live migration. After the first reboot,
the services in the VM guests are stopped and are not restarted until the upgrade is complete.
This process:
• Disables application monitoring on all node.
• Performs a rolling upgrade: the VM guest applications is stopped when the packages are
stopped.
• Upgrades cmappserver on all guests.
• Re-enables application monitoring.
To apply this process to upgrade:
1. Optional: If this is an upgrade from HP Serviceguard A.11.19 to HP Serviceguard A.11.20,
ensure that all service calls to the VM guest are unique, even if it means adding extra spaces.
NOTE: This is required for HP Serviceguard A.11.20.
2. Edit all of the packages to disable application monitoring (that is, comment out cmappmgr
calls).
3. Reapply the packages.
NOTE: Check that the various cmappmgr services have stopped. Else, stop them.
4. Performs a rolling upgrade on each node.
5. Ensure that all the HP Integrity VM guest packages are running.
