annoying SCSI errors

External Litronic PC card reader -> single ended to differential ended converter -> K-Class

The following messages keep reappearing and crowding syslog:

Dec 4 08:42:36 USPCAR01 vmunix:
Dec 4 08:42:36 USPCAR01 vmunix: SCSI: bp: 09381000
Dec 4 08:42:36 USPCAR01 vmunix: dev: ef003000
Dec 4 08:42:36 USPCAR01 vmunix: cdb: 12 01 80 00 ff 00
Dec 4 08:42:36 USPCAR01 vmunix: residual: ff

Dec 4 08:42:44 USPCAR01 vmunix: scb->cdb: 12 01 80 00 ff 00

These seem to be benign. Any ideas on the cause? Any way to fix, or to stop and/or filter these messages?

Thanks - Steve

Steve,

dev: ef003000 decodes as :-

Bus 00
scsi id 3
LUN 0
Flags 00

Therefore your device at c0t3d0 is causing the problem. I guess it's the card reader.
Check the scsi termination, cabling is ok. Could be the device. Can you swap it for another to check?
More than likely a scsi patch will fix it. Check you've got the latest scsi patches and their dependencies installed.

HTH

Dave.

Looks like SCSI reset error message. It's probably due to SCSI termination problem (eg: bad terminator, loose terminator). The suspected device is ..
ef 00 3 0 00 (c0t3d0)
ef = major number. (decimel=239)
Check what's the driver ..
# lsdev|grep 239
00 = bus number (ie card instance number)
3 = device scsi id
0 = lun 0 ie device logical unit number
Also check STM for any potential error.
# cstm

cstm>sel dev

cstm>infolog

I have experienced similar problems when using tape drives running through SCSI converter units. Do you have any jumper settings for termination in your converter? It may be worth checking this.

I had the same problem. The messages referred to a device that wasn't existing anymore. After removing the /dev/rdsk/, the messages never appeared again.
