d. When the copy interval expires, the disk process finishes the request that it is currently
handling and continues the disk revive operation again.
e. 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 $DSMSCM, DETAIL
STORAGE - Detailed Status DISK \ALM171.$DSMSCM

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 “Changing the Speed of a Revive Operation”
(page 99).
5. To stop the revive operation, see “Example of an INFO POOL Report” (page 135).
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.
Changing the Speed of a Revive Operation
While a revive operation is in progress, you can use the ALTER command to change its speed.
