When dump processing encounters an I/O error on the output tape,
DFSMShsm marks the tape unavailable. The tape is left under DFSMShsm’s
control to prevent re-release of the unavailable tape. This prevents
DFSMShsm from selecting the tape for scratch, and prevents other system
functions from encountering the unavailable tape before reinitialization.
Use the following procedure to remove the tape from DFSMShsm’s
control:
- Issue the LIST DUMPVOLUME SELECT(UNAVAILABLE) command to get a
list of the tapes marked unavailable.
- Run the relabel utility that is provided by your tape management
system, such as EDGINERS from DFSMSrmm. If no tape management system is available,
use the IEHINITT utility.
- Issue DELVOL volser DUMP(PURGE) for each
volume.
