When the server returns a volume to scratch status, the server starts the external media management program, issues a request to initialize, then issues a request to release a volume.
The external program must send a response to the release request. No matter what response is received from the external program, TSM returns the volume to scratch. For this reason, TSM and the external program can have conflicting information on which volumes are scratch. If an error occurs, the external program should log the failure so that the external library inventory can be synchronized later with TSM. The synchronization can be a manual operation.
Format of the request:
RELEASE libraryname volname
where:
Format of the external program response:
RELEASE libraryname volname COMPLETE, RESULT=resultcode
