Mirrored pair - recovery point lost

The synchronization recovery point for at least one mirrored pair within an asynchronous mirror consistency group has been lost.

This problem occurs for the following reasons:

Important:
  • The secondary volume's reserved capacity manages the recovery points that are created at the end of the mirror consistency group's synchronization cycle. If a problem has occurred on either the secondary volume itself or a repository volume associated with its reserved capacity, the volume is reinitialized and the recovery points are lost. After the problems have been fixed, new recovery points will be recreated during the next synchronization cycle.

  • Although this problem is only reported on the primary side (this storage array) of the mirror consistency group, the problem ONLY occurs because of problems on the secondary side (remote storage array). Therefore, if there are any problems associated with the secondary volume or a repository volume associated with its reserved capacity, fix those problems first. Fixing those problems may resolve this problem. Note that a synchronization cycle for the mirror consistency group may need to occur to re-establish the recovery points.

  • Problems with a secondary volume and/or its associated reserved capacity occur on a per mirrored pair basis and independently from other mirrored pairs within the mirror consistency group.

Recovery Steps

  1. Launch the storage management software for the remote storage array shown in the Details area, and then go to step 2.

  2. On the remote storage array, go to Home and select Recover from problems at the top of the page, and then go to step 3.

  3. Are there problems being reported on the remote storage array pertaining to a secondary volume or its associated reserved capacity?

    • If yes, go to step 4.

    • If no, go to step 6.

  4. Fix those problems on the remote storage array and then go to step 5 in this procedure.

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

    • If the problem is still being reported, go to step 6.

    • If the problem is no longer being reported, you are done with this procedure.

  6. Check if the affected mirror consistency group shown in the Details area is set for automatic or manual synchronization.

    • If automatic, go to step 7.

    • If manual, go to step 8.

  7. Do you want to wait for the automatic synchronization to occur at its scheduled time or manually resynchronize now?

    • If you want to wait for the automatic synchronization, then no further action is necessary. After the synchronization has occurred, this problem should no longer be reported.

    • If you want to manually resynchronize now, go to step 8.

  8. Manually resynchronize the affected mirror consistency group, and then go to step 9.

    1. Go to Storage > Asynchronous Mirroring. Then, select the Mirror Consistency Groups tab.

    2. Highlight the affected mirrored consistency group.

    3. Select Manually resynchronize under More.

    4. Go to step 9.

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