Upgrading cmappmgr/cmappserver combination
You can upgrade the VM guest monitoring functionality while upgrading HP Serviceguard, in two
ways. The difference between these two ways is the number of live migrations compared to the
VM guest application downtime.
Process 1: This process takes advantage of how cmappserver works. If cmappserver loses
communication with cmappmgr, it does not halt the applications that were being monitored, but
there is loss of the monitoring function.
This process:
• Disables application monitoring on all nodes.
• Performs a rolling upgrade.
• Upgrades cmappserver on all VM guests.
• Re-enables application monitoring.
To apply this process to upgrade VM guest monitoring functionality:
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.
