REFRESH Command

[Authorization: OPERATOR]

Use the REFRESH command to refresh volume status information, synchronize ARM catalogs with the TMC, or refresh the CA VM:Tape scratch pool definitions and assignment rules.

Use the REFRESH POINTER (NOSYNC version of this command under these conditions:

The TMC and tapes are shared with other tape management systems, such as other CA VM:Tape service virtual machines or CA 1
You just scratched tapes using the CA 1 TMSCLEAN utility (OS system) and you have a procedure in place on OS/390 to synchronize the ARM from OS/390

Use the REFRESH POINTER version of this command under these conditions:

There has been a substantial amount of enter or exit tape activity with a robot
If you make changes to the TMC using VMTBUILD to add or remove tapes

When you run the REFRESH command, it automatically notifies any ARM you are using of ARM tapes that have been scratched, either by the SCRATCH command or the TMSCLEAN utility, and the ARM updates its catalog with the new tape statuses. (Normally the SCRATCH command automatically notifies the ARM when it scratches tapes, but if the ARM was unavailable when the SCRATCH command was running, the REFRESH command is run to notify the ARM about the change of status for those tapes.)

Refresh scratch pool definitions and assignment rules each time you define a new scratch pool or change the definition of an existing scratch pool.

Note: For more information about the pointer file and the pick list files, and on scratch pool definitions and assignment rules, see the Administration Guide.
