Recovery Process Using Tape Automation

Using a media library is quite simple, no matter if the STRRCYBRM, RSTLIBBRM, RSTOBJBRM, or RSTDLOBRM commands are used, or if recovery is performed from the WRKMEDIBRM, WRKOBJBRM or WRKFLRBRM displays. As long as the required volume is in the media library, the restore operation is automatic, with no message being sent to the QSYSOPR message queue to load the volume. A message is sent to the BRMS log to notify the status of the restore operation. When the restore operation is complete, the last volume used remains in the tape drive unless otherwise specified. The end-of-tape option *UNLOAD returns the volume to its storage cell. If the required volume has been moved to another location, an inquiry message is sent to the QSYSOPR message queue. The message prompts the operator to insert the volume in the convenience I/O station or the high-capacity I/O area. If the volume is off-site, the operator can cancel the restore operation from this message. Once the volume is in either the convenience or high-capacity I/O areas, the media library places it in a storage cell, and BRMS mounts it in the drive to complete the restore operation.
