Resynchronize A Mirror - HP StorageWorks P9000 - Disk Arrays User Manual

- The Range column shows Mirror for at least one of the above pairs.
To be able to continue processing, do either of the following:
- Ensure that the Range column shows LU for all pairs in the same mirror.
- In the Preview list, select one pair in one mirror, and then other pairs in the mirror is
excluded.
6. From the Priority list, specify the scheduling order for resynchronizing selected pairs. If Range
is Mirror, the Priority list is disabled.

The serial number with the LDKC number.
The controller ID with the model name.
The path type.
8. The Resync Mode box indicates the type of pair resync that will take place when the operation
is executed.
Normal. The split pair whose status is PSUS or PSUE is recovered (resynchronized).
Delta. The delta resync operation is performed.
Return to standby. The pair status changes from HLDE to HOLD.
9. In the Error Level list, select one of the following options to take place if a failure occurs during
resync. Note that if the Range option is set to Mirror, Error Level options are disabled.
Mirror, to cause all pairs in the failed pair's mirror to be split.
LU, to cause only the specified pair or pairs that failed to be split.
10. Click Set.
1 1. See the Preview list to check the settings that you have made.
