Starting a Mirrored Disk
To preserve the older disk and copy it to the disk that has the newer time stamp,
start a path to the older disk first. This action causes an update to its timestamp,
making it more recent. Then you can start the rest of the volume. To monitor the
progress of the revive operation, periodically issue this command:
-> STATUS $DSMSCM, DETAIL
The above display shows:
•
The mirror disk is being revived.
•
The Revive Priority is 50.
•
The Revive Rate is 50. Thus, half the total number sectors are revived
between preemption checks. The estimated completion time is 13 minutes.
4. To change the speed of a revive operation, see page Changing the Speed of a
Revive Operation on page 7-7.
5. To stop the revive operation, see page Stopping a Revive Operation on page 7-7.
6. When no more tracks are left to be copied, the revive operation is complete. At that
time, the revived disk is in the STARTED state.
