LIST=BACKSTORE

This command is used when running the SVTSUTIL program to generate a list of all Virtual Volumes in VOLSER order that have been stacked on physical tape.

Syntax
LIST=BACKSTORE

Sample JCL can be found in HLQ.CCUUJCL (BACKSTOR).

The report shows each application data set name on each Virtual Volume and its associated physical tape primary and duplex VOLSERs, group and subgroup information, Virtual Volume size in megabytes, actual Virtual Volume size in megabytes, and DASD buffer compression percentage. The compression percentage is set to zero for any Virtual Volumes that do not contain compressed data. Totals of volumes, compressed volumes, and uncompressed volumes are displayed at the end, along with total uncompressed Virtual Volume size, total compressed size, and overall compression percentage. This report does not show Virtual Volumes stored in the DASD buffer, but that are not yet Externalized to physical tape.

Note: You can run this report when CA Vtape is active or inactive. When CA Vtape is inactive, include the VCAT and Global DD statements.
