DEFDENS Record

Use the DEFDENS Record to designate the density defaults CA VM:Tape is to use when complete density information is not specified on ALLOCATE or MOUNT commands.

You can designate default densities for each media type on the DEFDENS record. List the densities in order of preference. When CA VM:Tape needs to select a density for an allocation or mount request, it checks the media type specified on the request, then tries to use a tape drive that is compatible with the media type and the first density listed for that media type on the DEFDENS record. If such a drive is not available, CA VM:Tape tries to use a tape drive that is compatible with the media type and the second density listed for that media type on the DEFDENS record, then the third, and so on.

You can specify multiple density defaults for a single media type on one DEFDENS record, or you can use multiple DEFDENS records to specify multiple density defaults.

The DEFDENS Record is optional. If you do not specify it, CA VM:Tape uses the following density defaults:
