Defining DASDtape Characteristics

To create a DASDtape resource pool, specify the virtual address of the DASDtape minidisk and the length of the DASDtape in the following fields on the Modify Resource Pool poolname screen.

Tapedisk Address

This field identifies the virtual address of the DASDtape minidisk on which the backed-up data is stored. This virtual address must correspond to the address of an existing DASDtape minidisk. Multiple resource pools can access the same DASDtape minidisk. No more than one DASDtape minidisk can be specified for each resource pool.

Note: To define a DASDtape minidisk by updating the VMBACKUP CONFIG file, see the "TAPEDISK Record" section in the System Programmer Reference Guide.

Tape Length

This field determines the size, in feet, of a physical tape that the DASDtape is to approximate. This value can range from 300 through 3600. The default is 2400. This value, together with the indicated density, determines the maximum size in bytes of a DASDtape TAPE file.
