Starting a session does not restart pairs outside the SAN Volume Controller or Storwize consistency group

This condition occurs when you issue a Start command for a Metro Mirror session or Global Mirror session with SAN Volume Controller or Storwize® storage systems.

Problem

If you issue a Start command while Copy Services Manager is processing pair state changes and suspending events from the hardware, the pairs outside the storage system remote copy consistency group might not be restarted.

Action

Issue a Refresh States command for the session that contains the copy set that was not restarted. Then, issue the Start command to restart the pair on the hardware.
