We were bitten by the same bug.  A friend found the listing on DSIN of the
bug.  I have given the users who need to backup on our TU81+ the PHY_IO priv
(only about 6), others can still use our TU80 for backups.

SYMPTOM:

A BACKUP to a TU81+ or TK50 tape drive returns the following sequence of
errors after upgrading to VMS or MicroVMS Version 4.6:

     %BACKUP-F-LABELERR, error in tape label processing
     -SYSTEM-F-BADPARAM, bad parameter

<MORE TEXT>
Enter <RETURN> to continue, Exit, Redisplay, or ? for help:
This problem does not occur during BACKUPs to non-TMSCP tape devices.


WORKAROUND:

The process issuing the BACKUP command must have PHY_IO privilege.

     NOTE:  Installing BACKUP with privileges will not correct this
            problem because BACKUP is linked against the image
            ENCRYPSHR, which would also need to be installed.  However,
            this image is linked using /TRACEBACK and images linked
            with this qualifier cannot be installed.


SOLUTION:

This problem has been reported to VMS Engineering.
