HP StorageWorks Continuous Access EVA Administrator Guide (T3687-96043, December 2005)

Always verify that all components of the remote array are o perational before you fail over.
NOTE:
HP recommends that you not fail over any DR group more frequently than once every 15 minutes.
Performing failover and recovery
Failover and recovery procedures include such actions as failover, suspend, resume, disable failsafe,
mounting, and unmounting. You can per form these actions using the following interfaces and tools:
• Replication manager
• Replication manager command line interface
• Replication manager jobs
• Storage System Scripting Utility
• HP Command View EVA
For specific procedures, see the interface documentation.
Choosing a failover procedure
Table 3 summarizes situations that require a failover and those that do not. Each recommended action
corresponds to a procedure documented later in this chapter. Because replication can be bidirectional,
your array may be a source and a destination for separate DR groups. Use this table to customize
contingency plans for your environment.
