Doing an image backup on VMS5.1? Watch out for this GOTCHA!

$ backup/image disk tape
$! 	you fill up three tapes for one disk
$! 	you remove the write rings just to be safe
$ backup/image tape disk
$! 	at the end of restoring the first volume you get: 
$! 	%SYSTEM-I-IVCHAN, invalid I/O channel messages by the thousands
$! 	you take out your sledge hammer and operate on the hardware

Solution?  LEAVE THE WRITE RINGS IN THE TAPES!

Don't ask me why, but standalone backup wants write
access to that tape.  Any comments from other poor souls
who have seen this error?  Is it fixed in VMS5.3?
