Mirrored pair failed

This problem can occur in the following situations: (1) There is an underlying problem with the primary volume in an asynchronous mirrored pair or one or more of the repository volumes comprising its reserved capacity or (2) There is an integrity error on a repository volume associated with the reserved capacity.

Important

  • If there are any problems reported in the Problems area related to a primary volume failure or with one of the repository volumes associated with the reserved capacity, fix those problems first. Fixing those problems may resolve this problem.

  • No data has been lost as a result of the failed mirrored pair; however, the mirror consistency group was suspended. When a group is suspended, synchronization of mirrored pairs will not occur until you resolve the underlying problems and resume the group.

  • You have two options to fix this problem: (1) If you want to keep the mirrored pair relationship, you must first fix any problems with the primary volume or the repository volume associated with the reserved capacity or (2) If you do NOT want to keep the mirrored pair relationship, you must remove the mirrored pair. After it is removed, the group will resynchronize automatically.

Recovery Steps​

  1. Do you want to keep the mirrored pair relationship?

    • If yes, go to step 2.

    • If no, go to step 7.

  2. Fix all problems in the Problems area associated with the primary volume or the repository volume associated with the reserved capacity and then go to step 3.

  3. Were you able to resolve all of the problems in step 2?

    • If yes, go to step 4.

    • If no, the current mirrored pair relationship cannot be retained. Go to step 5.

  4. Resume the mirror consistency group, and then go to step 8.

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

    2. Highlight the affected mirrored consistency group shown in the Details area.

    3. Select Resume under More.

    4. Go to step 8.

  5. Do you want to re-establish the mirrored pair relationship using a new primary volume?

    • If yes, go to step 6.

    • If no, go to step 7.

  6. Re-establish the mirrored pair relationship, and then go to step 8.

    1. Go to Storage > Asynchronous Mirroring. Then, select the Mirrored Pairs tab.

    2. Highlight the affected mirrored pair shown in the Details area.

    3. Select Remove.

    4. Select the Mirror Consistency Groups tab.

    5. Highlight the affected mirrored consistency group shown in the Details area.

    6. Select Create Mirrored Pair and use a different primary volume.

    7. Go to step 8.

  7. Remove the mirrored pair.

    1. Go to Storage > Asynchronous Mirroring. Then, select the Mirrored Pairs tab.

    2. Highlight the affected mirrored pair shown in the Details area.

    3. Select Remove.

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