Explanation: VERIFY is an optional parameter that specifies whether verification, of conditions which might prevent a successful fast replication recovery, is performed before starting a fast replication recovery operation. Performing verification reduces the risk of a fast replication recovery failure. The following conditions are verified:
- The copy pool is not defined allowing fast reverse restore, but one or more volumes are in an existing FlashCopy® relationship.
- The copy pool is defined allowing fast reverse restore, but there are multiple FlashCopy targets, including non-DFSMShsm managed targets, associated with a source volume in the copy pool.
- The copy pool is defined allowing fast reverse restore, but one or more DASD are in the process of being dumped to tape.
There are multiple FlashCopy Incremental FlashCopy targets associated with a source volume in the copy pool.
The following options can be used with the VERIFY parameter:
- Y
- specifies that source volumes require verification. This option is the default.
- N
- specifies that source volumes do not require verification. Use VERIFY(N) only when all volumes are SnapShot capable, or if the QUERY COPYPOOL command has been issued to verify that there are not any unexpected FlashCopy relationships.
Note:
- VERIFY(N) cannot be specified when a copy pool is defined allowing fast reverse restore unless a previous FRRECOV COPYPOOL operation has determined the copy pool backup version is no longer eligible for fast reverse restore and regular fast replication recovery can be used.
Defaults: If you do not specify the VERIFY parameter, the default is Y (verification is performed).
