I have tried to do a mksysb backup of my aix5.2 tsm server 5.2 to tape

                 Either write protected or in use.

I have tried to delete tape devices and only configure the dat drive
but
with no success. Is there any suggestions:-

The tape is fine, no problems with tape or tape drive...

This isn't AIX-L, but...  I've seen that error where the operator kicks
off a mksysb and there is no tape in the drive. In your case, I would
obviously assure that the write-protect tab on the tape cartridge is in
the right position to allow writing. If still a problem, try another
tape. If it persists, then perhaps the drive is not properly sensing
the tape. You might also try 'lsof' to see if anything else is meddling
with the drive.
