Mirror Data Unsynchronized

What Caused the Problem?

The data on the secondary logical drive is no longer synchronized with the primary logical drive. This occurs when the primary logical drive is unable to communicate with the secondary logical drive, or if the Mirror Repository logical drives have failed. 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 errors present in the Recovery Guru Summary area, perform those recovery procedures before completing the steps in this procedure.
2 Verify your resynchronization settings by selecting the primary logical drive, then selecting the Logical Drive >> Properties menu option and viewing the Mirroring tab.
If... Then...
Your resynchronization is set to Automatic Go to step 3.
Your resynchronization is set to Manual Try to start resynchronization by selecting the primary logical drive and then selecting the Logical Drive >> Remote Mirroring >> Resume menu option.

If the mirror status changes to Synchronizing, go to step 7.

4 Check the switch the storage subsystem is connected to for indications of a switch port, interface transceiver (GBIC or SFP), or other switch failure.
If... Then...
There is a problem with the switch Correct the problem.

Go to step 7.

There is not a problem with the switch Go to step 5.
5 If the fabric consists of multiple switches, verify that the cables connecting the switches are not loose, disconnected, or damaged.

Go to step 7.

A loose or disconnected cable is detected Reconnect the cable.

Go to step 7.
