HP Serviceguard Toolkit for Integrity Virtual Servers User Guide B.02.00, March 2012

NOTE: With the HP Serviceguard A.11.20 release, application monitoring is now supported
for VM or vPar guests that use online VM or vPar guest migration. It is not supported with the
HP Serviceguard A.11.19. To support online VM or vPar guest migration, all service command
strings sent to the VM or vPar guest must be unique. This means, if two instances of the same
application are started and monitored in the VM or vPar guest using cmappmgr, the service
strings must be different, even if a space needs to be added to one of them.
6. Test application monitoring and VM or vPar guest failover operation.
After VM or vPar guest application monitoring is configured, you must test application restart
and VM or vPar guest failover by terminating the monitored application on the VM or vPar
guest and verifying:
• The SERVICE_RESTART counter for the cmappmgr SERVICE_CMD used to monitor the
application increases.
• The VM or vPar guest fails over to a standby VM or vPar Host node after the
SERVICE_RESTART value exceeds.
Example of Configuring application monitoring service
# cmdeployvpkg -P slvm1 -x merge -x appmon
