Reserve or lock volumes during DLMAINT processing

The VOLUME statement specifies whether DASD volumes processed during BACKUP, RESTORE, or RESYNC processing are to be RESERVEd or LOCKed. The default is not to issue a RESERVE or LOCK during DLMAINT operations. The RESERVE operand indicates that all volumes processed by subsequent DLMAINT statements are to be RESERVEd .The RESERVE is held for the duration of DLMAINT processing or until a VOLUME RELEASE statement is encountered. The LIST operand indicates that a message is to be issued indicating whether the RESERVE or RELEASE was successful.

Note: If RESERVE is specified, other applications will not be able to allocate to the device while DLMAINT is working with the volume.

VOLUME LIST

LOCK | UNLOCK

RESERVE | RELEASE

LIST

Function: This is an optional parameter. The LIST operand indicates that a message is to be issued indicating whether the RESERVE or RELEASE was successful.

Default: None

Format: LIST

LOCK | UNLOCK

Function: This is an optional parameter. The LOCK operand can be specified during RESYNC processing when the DLimit product is currently also active, and indicates that the dadsm exits will not add or subtract for any dadsm request on that volume. This ensures that the space will not change while a volume is being processed by RESYNC.

Default: NOLOCK

Format: LOCK or NOLOCK

RESERVE | RELEASE

Function: This is a required parameter. The RESERVE operand indicates that all volumes processed by subsequent DLMAINT statements are to be RESERVEd. The RESERVE is held for the duration of DLMAINT processing or until a VOLUME RELEASE statement is encountered.

Default: None

Format: RESERVE or RELEASE

Example - In the following example, volumes to be processed by RESYNC are RESERVEd to prevent any datasets from being created or deleted during RESYNC processing in order to make the RESYNC more accurate.
