When the following conditions apply, a ShadowImage pair is suspended, and the status of the pair is changed to PSUE:
- the storage system detects an error condition related to an update copy operation
- the storage system cannot keep the pair mirrored
At this time, write I/Os to the P-VOL continue and all tracks of the P-VOL are saved as differential data. When the pair is resynchronized, the pair status changes to Resync/PENDING, and the entire P-VOL is copied to the S-VOL. For a split pair, resynchronization is completed in a short time. But it takes the same period of time for a suspended pair to be resynchronized as the initial copy operation.
You can use CCI to change the status of the pair to PSUE by using the pairsplit -S command.
You can change the status of the pair to PSUE by using the following procedure.
