Mirror consistency group - synchronization paused

A mirror consistency group's synchronization has been paused. This problem typically occurs when there are any communication problems between the local and remote storage array or problems with the secondary volumes, or when the controller that owns one of the mirrored volumes within the affected asynchronous mirror consistency group is in an offline (non-optimal) state.

Important
  • If the mirror consistency group's synchronization was paused due to a controller problem that cannot be resolved quickly, synchronization can be resumed on dual-controller storage arrays by transferring ownership of all mirrored volumes within the mirror consistency group from the non-optimal controller to the alternate controller. Contact your Technical Support Engineer for assistance.

  • Although this problem is only reported on the primary side (this storage array) of the mirror consistency group, the problem can occur because of problems on the remote storage array. Therefore, check both the local and remote storage array for the reasons listed above and fix those problems first. Fixing those problem may resolve this problem.

Recovery Steps

  1. Are there any other problems (such as controller, secondary volume, or communication issues) being reported in the Problems area related to the affected mirror consistency group on either the local or remote storage?

    • If yes, attempt to fix those problems and then go to step 2. If needed, contact your Technical Support Engineer for assistance.

    • If no, go to step 3.

  2. Were you able to fix the other problems being reported in the Problems area related to the mirror consistency group?

    • If yes, go to step 5. The synchronization of the mirror consistency group should resume automatically.

    • If no, go to step 3.

  3. Manually collect support data from the storage array.

    1. Go to Support > Support Center. Then, select the Diagnostics tab.

    2. Select the Collect Support Data link to save the support data to a file.

  4. Contact your Technical Support Engineer using the information in the upper right-corner of the Support Center.

  5. Select Recheck to ensure the problem has been resolved.
