[Animesh Chakraborty]

Hi All,
I am getting following scsi error in syslog every one hour
SCSI: Request Timeout; Abort -- lbolt: 276781692, dev: cb006000, io_id: 1ddd8

SCSI: Request Timeout; Abort -- lbolt: 277143897, dev: cb006000, io_id: 1ddff

SCSI: Request Timeout; Abort -- lbolt: 277350082, dev: cb006000, io_id: 1de07

How to find out which device giving problem.

Thanks in advance

Hi Sanjay,
Thanks for your response.
In my case the dev=cb006000

cb 00 6 0 00
__ __ _ _ __
| | | | |
major# | target | flags
| |
bus# lun
But the major number cb(203 in dec) can't find
in my machine.
Any idea ? In this case c*t6d0 ?
Thanks
Animesh

Major 203 is probably the sctl (SCSI pass-through) driver. See the lsdev(1M) output on your system. For details on the sctl driver, see the scsi_ctl(7) manual page.

The following command will probably find the right device file:

find /dev | xargs ll | grep 203

Hi Animesh,

Looks like c0t6d0 to me.

cb006000

cb --> Major No,
00 --> Bus (c0)
6 --> SCSI ID (t6)
0 --> LUN (d0)
00 --> Flag

Hope this helps.

Thanks

Hi Animesh,

The major no 203 refers to the SCSI controller.

To find the driver associated with this major No.,do

lsdev |grep 203
The result would be
203 -1 sctl ctl
Do "ioscan -fn |grep sctl"
The result would be
ctl 10/0.7.0 sctl CLAIMED DEVICE Initiator
ctl 10/12/5.7.0 sctl CLAIMED DEVICE Initiator
This shows that the majot no referes to the Controller Driver.

Hope this helps.

Thanks
