A parity error occurred on the first end volume label.
Cause.
A parity error was detected on one of the two end volume labels. The end of the tape is
particularly vulnerable to parity errors. For example, tapes with reflective strips cause a bump in
the tape; sudden stopping at the end causes tape stretching; and so on. The tape format has
duplicate end volume labels in hope that at least one of them will be readable.
Effect.
RESTORE proceeds.
Recovery.
After the restore is finished, the tape and tape drive should be investigated.
