I guess the bad device is the Micropolis. I had some 'queue full' with 32
tagged commands on my Conner, so I reduced it to 31. The Micropolis is not
used very often, had no 'queue full', but I didn't want to test it...
The Aiih was in different locations, e2fsck, swapper, etc. and happened
while fscking the disks after an unclean shutdown, so I guess I could
repeat it as often as I want...but maybe in 'read-only'-mode...there was
nothing to fix because I had not accessed the disks.
One nice enhancement would be to allow different depths of tagged queues
on each device/lun.
I heard from the Quantum drives that need a firmware upgrate from
ftp.quantum.com (it's not on their webserver :-( )
Does there is a possibility to intentionally reset the scsi-bus, e.g. via
echo "scsi reset 0 0" > /proc/scsi
I tried to implement it, but it kept resetting the bus. The reason for
this are hot-pluggable disks...Yes, I have on of those frames that allow
hot-plugging of disks and that halt the scsi-bus while inserting. I tried
it and it worked fine iff I used 'scsi-rescan'.
Please send me any fixes and I'll test them.
