Symptômes
After a migration from another vendor Virtual Tape System to the DLm using third-party software, the DLMSCR job is running a long time and producing numerous 'volume not found' messages.
DLMSCR VER 4.42 DLMCTRL = C5FF PARM(TYPE=RMM,PREFIX=IB,PREFIXLN=1,DEV=C 2021/02/18 08:45:12 VOLUME BFL111 REQUEST REJECT - VOLUME NOT FOUND 2021/02/18 08:45:12 VOLUME BFL499 REQUEST REJECT - VOLUME NOT FOUND 2021/02/18 08:45:12 VOLUME BFL502 REQUEST REJECT - VOLUME NOT FOUND 2021/02/18 08:45:12 VOLUME BFL503 REQUEST REJECT - VOLUME NOT FOUND 2021/02/18 08:45:12 VOLUME BFL504 REQUEST REJECT - VOLUME NOT FOUND 2021/02/18 08:45:12 VOLUME BFL601 REQUEST REJECT - VOLUME NOT FOUND ...
Cause
There are "B" prefixed tapes in both the legacy VTS and the DLm, so that when the DLMSCR job inputs the daily or full scratch report, it is receiving input for both DLm tapes and VTS tapes.
Résolution
The DLm should not share tape ranges with another tape system.
