Attributes of primary volumes

When you use the ADDVOL command to add a primary volume to DFSMShsm, you assign attributes to that primary volume. You can choose the following primary volume attributes:
  • AUTOMIGRATION or NOAUTOMIGRATION
  • AUTORECALL or NOAUTORECALL
  • AUTOBACKUP or NOAUTOBACKUP
  • BACKUPDEVICECATEGORY
  • AUTODUMP or NOAUTODUMP

The use of the first two primary volume attributes is described in this topic. The use of the last three attributes is described in Availability management of non-SMS-managed storage.

Each DFSMShsm host can decide whether primary volumes are processed by automatic space management, automatic backup, or automatic dump. However, if an automatic process controls a primary volume in any DFSMShsm host, DFSMShsm considers the volume to be automatically controlled for that process. For example, assume you specify the following in DFSMShsm hosts 1 and 2:
ADDVOL VOL006 PRIMARY(AUTOMIGRATION) UNIT(3390)
Then you specify the following in DFSMShsm host 3:
ADDVOL VOL006 PRIMARY(NOAUTOMIGRATION) UNIT(3390)

DFSMShsm considers VOL006 to be controlled by automatic space management.
