Tape drive does not support density selection.
Cause.
The BACKUP DENSITY option was specified, but the tape drive does not implement density
selection.
Effect.
BACKUP proceeds. Tape drive uses physical density setting.
Recovery.
Informational message only; no corrective action is needed.

Bad tape format (End-of-file encountered where beginning
volume label expected).
Cause.
An attempt was made to restore a tape, but a BACKUP tape in the proper format could not
be found. There are three possible reasons:
•
BACKUP was stopped in the middle of a backup operation, resulting in an incomplete BACKUP
tape. The "Bad Tape Format" was detected when unwanted or meaningless information was
encountered at the interruption point on the tape.
•
The BACKUP tape was corrupted in some way.
•
Either BACKUP produced an invalid tape or RESTORE is not checking correctly due to a
software error.
Effect.
RESTORE terminates.
Recovery.
If the invalid format is the result of one of the first two causes, the files cannot be restored.
If you suspect the problem is a result of the third cause, contact your service provider and provide
all relevant information:
•
The information in this message
•
Description of the problem and accompanying symptoms
•
Supporting documentation such as Event Management Service (EMS) logs, trace files, and a
processor dump, if applicable
If your local operation procedures require contacting the GCSC, supply your system number and
the numbers and versions of all related products as well.
7516
Unable to read beginning volume label(Parity error).
Cause.
A parity error was encountered when the beginning volume label was read. Possible causes
are:
•
The density used to record the tape and the current density setting on the tape drive are
different.
•
The tape-drive heads are dirty.
•
The tape drive in use needs realignment.
•
The tape drive that wrote the tape needs realignment.
Effect.
BACKUP or RESTORE unloads the tape and prompts for a reel.
Recovery.
Verify the density and try again. If the parity error persists, type STOP at the prompt.
Try other tape drives. If parity errors occur on a number of tape drives, the tape cannot be restored.
