Explanation: FROMDUMP is an optional parameter
that indicates to DFSMShsm to recover the specified volume from a
dump tape.
The following options can be used with the FROMDUMP parameter:
- APPLYINCREMENTAL
- Specifies that an incremental volume recovery process is to
follow immediately after the volume restore and is to be part of the
single request to recover a specific volume.
- DUMPCLASS
- Specifies which dump class to use for the volume recovery.
- dclass
- Is the name of the dump class to use for the volume recovery.
- DUMPVOLUME
- Specifies which specific dump copy to use for the volume recovery.
- dvol
- Is the name of the dump volume to use for volume recovery.
- PARTIALOK
- Allows recovery of a backup copy from a partial dump version.
If the requested dump version is complete, that is, not a partial
dump version, the PARTIALOK parameter is ignored.
- RESUME
- Specifies whether resuming a previously failed recovery is attempted.
If the previous recovery was successful, the RESUME parameter is ignored.
- NO
- Specifies a previously failed recovery should not be resumed.
A full recovery will be attempted instead.
- YES
- Specifies a previously failed recovery should be resumed. This
is the default.
Note: - APPLYINCREMENTAL can be specified only when recovering a specific
volume (TOVOLUME) from a dump tape copy.
- PARTIALOK and RESUME can be specified only when recovering a copy
pool from a dump tape copy.
Defaults: If the version to be recovered
resides on a dump tape only, DFSMShsm recovers the version from tape.
If the version exists both on DASD and tape, DFSMShsm recovers the
DASD copy.
