>Description:
When dump(8)-ing to a tape drive with a read-protected medium inserted,
dump reports "End of tape reached" and asks for the next medium.
However, the 2nd tape is created as "volume 2", making "restore"
impossible:
jocelyn% restore -t -f /dev/rst0
Dump date: Mon Dec 29 22:48:34 1997
Dumped from: the epoch
Level 0 dump of an unlisted file system on jocelyn.rhein.de:/dev/rsd1a
Label: none
Tape is not volume 1 of the dump
>How-To-Repeat:
see above.
>Fix:
Workaround:
If you get the offer to change the tapes, abort the dump instead, and
start anew.
