Managing HP Serviceguard A.11.20.10 for Linux, December 2012

# cmhaltpkg pkg1
# cmrunpkg -n node1 pkg1
# cmmodpkg -e pkg1
• Fail one of the systems. For example, turn off the power on node 1. Make sure the package
starts up on node 2.
• Repeat failover from node 2 back to node 1.
2. Be sure to test all combinations of application load during the testing. Repeat the failover
processes under different application states such as heavy user load versus no user load, batch
jobs versus online transactions, etc.
3. Record timelines of the amount of time spent during the failover for each application state. A
sample timeline might be 45 seconds to reconfigure the cluster, 15 seconds to run fsck on
the filesystems, 30 seconds to start the application and 3 minutes to recover the database.
