ABARSUNITNAME: Specifying a unit name for ABARS

Explanation: ABARSUNITNAME(unittype) is used to specify the unit to be used when invoking aggregate backup or aggregate recovery.

Tape Library Relationship: A UNITNAME can be used for filtering in the ACS routines. If you specify the unittype for this command, it will be sent to the ACS routines in SMS for the ABARS function.

unittype specifies the tape unit to be allocated for the control file, instruction/activity log, and data file. The valid types of tape units are:
  • 3400-3, 3400-4, 3400-5, 3400-6, 3400-9
  • 3480
  • 3480X
  • 3490
  • 3590-1

You can substitute an esoteric tape unit defined with the USERUNITTABLE parameter of the SETSYS command. If you specify an esoteric tape unit name that does not exist in the user unit table, the command fails. Specify 3400-9 when your 3480 Magnetic Tape Subsystem simulates your 3420 tape drives.

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

SETSYS default: If unitname is not specified by the SETSYS ABARSUNITNAME(unitname) or the UNIT parameter on the ABACKUP or ARECOVER command, it defaults to 3590-1.
