Designing Disaster Tolerant High Availability Clusters, 10th Edition, March 2003 (B7660-90013)

Building a Continental Cluster
Testing the Continental Cluster
Chapter 5 247
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 cmrecovercl -f as well as cmrecovercl
Depending on the condition, the primary packages should be running
to test real life failures and recovery procedures.
4. After each scenario in tests 2-4, restore both clusters to their
production state, restart the primary package(s) (as well as any data
sender and data receiver packages) and note any issues, time delays,
etc.
5. Halt the monitor package on one cluster. Halt the other cluster. No
notifications are generated that the other cluster has failed. What
mechanism is available to the organization to monitor the monitor?
6. Halt the packages on one cluster, but do not halt the cluster. No
notifications are generated that the packages on that cluster have
failed. What mechanism is available to the organization to monitor
package status?
NOTE ContinentalClusters monitors cluster status, but not package status.
7. View the status of the continental cluster.
