1720 Metro Mirror (remote copy) - Relationship has stopped and lost synchronization, for reason other than a persistent I/O error (LSYNC)

Explanation

A remote copy relationship or consistency group needs to be restarted. In a Metro Mirror (remote copy) or Global Mirror operation, the relationship has stopped and lost synchronization, for a reason other than a persistent I/O error.

User response

The administrator must examine the state of the system to validate that everything is online to allow a restart to work. Examining the state of the system also requires checking the partner Fibre Channel (FC) port masks on both clusters.

  1. If the partner FC port mask was changed recently, check that the correct mask was selected.
  2. Perform whatever steps are needed to maintain a consistent secondary volume, if desired.
  3. The administrator must issue a start command.
