Hi All,
Here's something to try on your RS 2030 workstation :
(READ ON FIRST!)
1) put a tape cartridge in the tape drive
2) TAR some "stuff" onto the tape using /dev/mt/ctape4
(i.e. so the tape doesn't rewind on completion)
Be sure you've put enough stuff on the tape that
a rewind will take greater than 30 sec.
3) type "mt -f /dev/mt/ctape0 rew & ; mt -f /dev/mt/ctape0 rew"
The first one will grab the drive for rewind and want for completion
in background (nothing new here). The second rewind will block waiting
to the tape tape also (still nothing new).
The kicker: the second rewind will get an SCSI timeout error...
This causes a system panic, and reboot, and /etc/savecore saving
all kinds on nonsense...!!!
I could see where this panic would be useful on a disc, but plain
annoying on the tape cartridge drive. (esp. since I have users who
are prone to doing "something" that would have a pending tape
rewind waiting for long periods for access to the drive)
Anyway have a bug-fix for this?
Cheers
Cliff
