VMTAPE CONFIG File Record Reference › DEFDENS Record › Example

Example

Assume the VMTAPE CONFIG file contains these records:

DEFMEDIA ENHANCED CART 
DEFDENS ENHANCED ENHXF ENH
DEFDENS CART EXF E XF 38K

CA VM:Tape receives a scratch tape mount request that does not specify media type or density. CA VM:Tape selects an enhanced capacity cartridge, because the DEFMEDIA Record lists ENHAnced as the first choice of media when media is not specified. CA VM:Tape then selects density ENHXF, which the DEFDENS Record lists as the first choice of density for enhanced capacity cartridges when density is not specified.

Or CA VM:Tape receives a mount request that specifies media type CART and other options that result in a list of eligible drives with no 3490Es. In this case, CA VM:Tape selects XF as the default density because the DEFDENS Record lists XF as the first choice of density for cartridges that CA VM:Tape has available.
