AUTODUMP and NOAUTODUMP: Specifying whether a volume is eligible for automatic dumping to tape

Explanation: AUTODUMP(class) and NOAUTODUMP are mutually exclusive, optional subparameters of the PRIMARY and MIGRATION parameters specifying whether the volume is eligible for a full-volume automatic dump.
AUTODUMP
specifies that the primary or migration volume is eligible for a full-volume automatic dump and selects the dump classes that contain the dump copies. For class, substitute one previously defined dump class for each of the output copies wanted for the dump. You must have a minimum of one class selected, but you can select a maximum of five classes. Each dump class, class, must be predefined using the DUMPCLASS parameter of the DEFINE command before you attempt to use the AUTODUMP parameter of the ADDVOL command.

The FREQUENCY and DAY subparameters of the DUMPCLASS parameter of the DEFINE command determine how often a primary volume is dumped to a given dump class.

NOAUTODUMP
specifies that the primary or migration volume is not eligible for a full-volume automatic dump.

Defaults: If you are adding a primary or migration level 1 volume to DFSMShsm, the default is NOAUTODUMP.

Note:
  1. In a multiple-DFSMShsm-host environment, the AUTODUMP parameter can be different in the different DFSMShsm hosts. If you add a volume to more than one DFSMShsm host with different dump class values, the dump classes will be that of the last ADDVOL command processed.
  2. The migration volume eligibility is applicable only to migration level 1 volumes and is ignored for migration level 2 volumes.
