Additional considerations for running a fire drill

Follow these guidelines for fire drills in a Windows environment:

  • The primary and secondary sites must be fully configured with TrueCopy/HP-XP-CA replication and the global cluster option. The configuration must follow the applicable instructions in the Storage Foundation and High Availability Solutions for Windows documentation for configuring disaster recovery with TrueCopy/HP-XP-CA.

  • The secondary system where you plan to run the fire drill must have access to the replicated volumes.

  • Ensure that Hitachi RAID Manager / Command Control Interface (CCI) is installed.

  • You must configure ShadowImage pairs (for Hitachi) before running the Fire Drill wizard.

  • During a fire drill, Volume Manager commands like vxassist rescan can cause performance issues due to the number of Volume Manager objects like diskgroups, disks, and volumes. To avoid this, you must increase the timeout value of the agent for larger configurations.
