TAPEDISK Record

Use the TAPEDISK record to identify the virtual address of a minidisk to which CA VM:Backup can write DASDtape data.

TAPEDISK vaddr label

CA VM:Backup can use more than one DASDtape minidisk during job execution. All tapes defined to the resource pool are created on the associated DASDtape minidisk as they are used in backup and MPC jobs. Each DASDtape, which contains a DASD image of a CA VM:Backup physical tape, is stored as a CMS file with a filename that corresponds to the volser of the tape and a filetype of TAPE.

All DASDtape minidisks must be CMS minidisks formatted in 4K-byte blocks. You cannot use DASDtape minidisks for any other purpose.

Definitions

vaddr

Specifies the virtual address of a DASDtape minidisk. Addresses must be in the range 0100-01EF or 1000-1FFF.

label

Specifies the minidisk label of the CMS-formatted DASDtape minidisk on which the data is located or to which the data is to be written. The minidisk label is used by CA VM:Backup to verify the minidisk at the specified virtual address; therefore, the label cannot be blank.

Description

Each TAPEDISK record must be followed by a corresponding TAPEPOOL record in the VMBACKUP CONFIG file; the TAPEPOOL records must specify MEDIA DASD. No DASDtape minidisks are defined by default.

Interactive Reconfiguration

You cannot interactively reconfigure the TAPEDISK record through CA VM:Backup system administrator screens.
