[plug] SCSI tape problem

[Workshop users]

Yes thay are both on the same controller the backups get done at about 10pm
so the server should be under very little load. Our plan is if we can't fix
it is to get another controller so we have  1 for the tape and 1 for the
HDD.

	Is the tape device the only thing on the controller? or is your
seagate hd also on it?



	I have heard from an experienced linux/ISP person before that they
wouldnt use the Adaptec controllers because under heavy load they would
throw spurious errors. I run one in a desktop and its fine, but I never come
close to maxing the thing out.

	If your harddrive(s) and tape are on the same controller, it might
be worth borrowing another and moving the tape to that, just to rule out the
problem.

	I run a very similat setup here.  They only time I've had issues is
when 2
	applications tried to access the DAT drive at the same time.   it
actually
	required a reebot to fix it :(

	If you mailed me (offlist) your
	/proc/scsi/scsi
	/proc/scsi/aic7xxx/0
	/var/log/dmesg

	and
	the output from dmesg
	then  I could have a look to see if I saw anything strange (or maybe
bring
	meaning to the problem).


	Yours Tony.
