OSGROUP Parmlib Member

The OSGROUP Parmlib member contains group attribute definitions. Groups define policies that are applied to a Virtual Volumes subset. Group attributes control certain behaviors. For example, if compression is used or which VOLSERs pool a scratch tape is chosen from to service the tape mount.

While active, the Subsystem can dynamically reload the group member attributes by using the SVTn REFRESH=GROUP console command.

Because the group definitions are local definitions that are Subsystem-specific, issue the SVTn REFRESH=GROUP console command for each Subsystem that shares a common modified group member. Otherwise, only the Subsystem for which the command was issued picks up the changes.

OSGROUP contains the index section Group Definitions, which references one or more group sections with customizable names.
