The DYNCAT BACKUP command backs up the Catalog files. Data set
CA Dynam/T BKUP is established with mode 1600 and owner OP. Option 2 is
used on the TLBL to force unload at CLOSE. A scratch tape with the specified
owner is not found on a drive capable of writing in 1600 mode; a subsequent
CADT008D MOUNT message is issued specifying owner OP and mode 1600.
The operator responds 299.
However, the tape on 299 has a mismatching owner, so message CADT010D is
issued. The operator responds EOB/END, and mounts a tape with owner OP on
29A. 29A is capable of writing in 1600 mode, the volume is allocated and
processing continues.
The operator could also have responded to the CADT010D message with
ACCEPT; then the indicated volume would be reinitialized with owner OP.
