Unable to Update Remote Mirror

What Caused the Problem?

A storage subsystem world-wide name change occurred on this storage subsystem and it was unable to establish a connection and notify a remote storage subsystem with mirror relationships of the change. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Important Notes

Recovery Steps

1

If there are other errors listed in the Recovery Guru Summary area, perform those recovery procedures before completing the steps in this procedure.

2

Save the current logical drive configuration from the Storage Subsystem Profile. This information will be used to determine the mirror relationships associated with the affected remote storage subsystem so the configuration can be duplicated. To save the logical drive information, select the View>>Storage Subsystem Profile menu option and select the Logical Drives tab. Use the Save As button to save the information to a file.

3

You must now re-create the mirror relationships for all mirrored logical drives associated with the remote storage subsystem. Use the file saved in Step 2 to determine which logical drives are associated with the remote storage subsystem. For each of these logical drives, perform the following steps:

a

Delete the mirror relationship from the local storage subsystem by highlighting the local logical drive in the Subsystem Management Window and selecting the Logical Drive>>Remote Mirroring>> Remove Mirror Relationship menu option.

Note: If there is a connection problem between the local and remote storage subsystems, the mirror relationship on the remote storage subsystem will not be removed. If the remote mirror relationship is displayed in the remote Subsystem Management Window after the above action, highlight that logical drive from the remote Subsystem Management Window and select the Logical Drive>>Remote Mirroring>> Remove Mirror Relationship menu option. You must resolve the connection problem before the mirror relationship can be re-created. Check the Recovery Gurus on both the local and remote storage subsystems for possible problems. If the Recovery Gurus do not show any problems, check for damaged fibre cables, loose connections, or a malfunctioning switch between the two storage subsystems.

b

Using the file saved in Step 2 as a guide, re-create the mirror relationship by highlighting the logical drive you wish to be the primary logical drive on the local storage subsystem and selecting the Logical Drive>>Remote Mirroring>>Create menu option.

Select Recheck to rerun the Recovery Guru to ensure that the failure has been fixed.
