MAXDUMPRECOVERTASKS: Specifying the maximum number of concurrent volume recovery from dump tasks

Explanation: MAXDUMPRECOVERTASKS(nn) is an optional parameter specifying the maximum number of volume recovery from dump tasks DFSMShsm can concurrently process. This parameter allows you to set the appropriate tasking level to recover individual volumes, based on the number of tape drives available. The actual number of effective tasks will be limited by the number of tape drives available and dump stacking value.

For nn, specify a decimal number from 1 to 64 to represent the number of volume recovery from dump tasks to be processed concurrently.

Note:
  1. Special care must be taken when considering dump classes and their dump stacking values. A higher dump stacking value requires fewer tapes; however, the higher the number of volumes dumped onto a single tape, the greater the likelihood that a single tape will be needed for multiple recovery tasks. If the specified number of concurrent tasks is greater than the number of tape drives in use, the maximum number of concurrent tasks will be limited.

SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed volumes.

SETSYS default: None.

DFSMShsm default: If you do not specify this parameter on any SETSYS command, the default is 1.
