HP Serviceguard Metrocluster manual # cmviewconcl, Testing the Continentalclusters

command. Any data receiver packages on the monitoring cluster must halt and the recovery packages must start with package switching enabled. Halt the recovery packages.

3.Test 2 should be rerun under a variety of conditions (and multiple conditions) such as the following:

•Rebooting and powering off systems one at a time.

•Rebooting and powering off all systems at the same time.

◦Running the monitor package on each node in each cluster.

◦Disconnecting the WAN connection between the clusters.

If physical data replication is used, disconnect the physical replication links between the disk arrays:

◦

◦

Powering off the disk array at the primary site.

Powering off the disk array at the recovery site.

•Testing the cmrecovercl -fas well as the cmrecovercl command.

Depending on the condition, the primary packages must be running to test real life failures and recovery procedures.

4.After each scenario in tests 2-3, restore both clusters to their production state, restart the primary package (as well as any data sender and data receiver packages) and note any issues, including time delays, and so on.

5.Halt the monitor package on one cluster. Halt the other cluster. Notifications that the other cluster has failed are not generated. Test the mechanisms available to detect manual shutdown of Continentalclusters monitor daemon.

6.Halt the packages on one cluster, but do not halt the cluster. Notifications that the packages on that cluster have failed are not generated. Test the mechanisms available to detect the manual shutdown or failure of primary packages.

7.After the testing is complete, view the status of Continentalclusters:
