Explanation
The system has enforced the single mode recording
rules or has recognized a non-supported recording mode. The message
display may be in one of two forms:
- When OVERRIDDEN appears in the message display, the den or trtch
fields indicate the value selected by the system.
- When IGNORED appears in the message display, the den or trtch
fields are omitted.
In the message text:
- dev
- Device number.
- ser
- Volume serial number.
- labtyp
- The label type of the mounted volume (either SL, NL, AL, or NSL).
- den
- The density of the volume to be mounted.
- trtch
- This indicates the recording mode as COMP (compaction) or NOCOMP
(non-compaction).
Note: The COMP restriction applies only to IBM® standard labels.
- jjj
- Job name.
- sss
- Step name.
- dsname
- Data set name.
System action
The job step continues processing.
