Starting a Mirrored Disk

1. Verify the current state of the disk volume:

-> STATUS $DSMSCM-*

2. If all paths are not in the STOPPED state, substate DOWN:

-> RESET $DSMSCM

3. Start the disk process:

-> START $DSMSCM

The disk revive operation does the following:

a. The disk process copies the percentage of the total number or sectors that

have been specified by the REVIVERATE attribute from the disk with the

newer timestamp to the disk that is being revived (the disk with the older

timestamp).

b. The disk process checks for other work to be done. If there are no other

requests pending, the disk process starts the disk revive operation again.

c. The disk process handles any waiting requests.

d. When the copy interval expires, the disk process finishes the request that it is

currently handling and continues the disk revive operation again.
