Determing device from error message

[Randy Brown_1]

We recieved the following error messages in our syslog:

Feb 4 21:52:53 ds1-nhdr vmunix: SCSI: Request Timeout -- lbolt:
> 46931652, dev: cd030000
> Feb 4 21:52:53 ds1-nhdr vmunix: lbolt_at_timeout:
> 46871552, lbolt_at_start: 46871552
> Feb 4 21:52:53 ds1-nhdr vmunix: SCSI: Abort -- lbolt: 46931652, dev:
> cd030000, io_id: 31600b5

In looking around on our system we came up with two possible culprits. /dev/rmt/0m and /dev/dsk/c0t3d0

How can we distinguish:

ds1-nhdr:brianm:16$ ls -l /dev/rmt/0m
crw-rw-rw- 2 bin bin 205 0x030000 Feb 4 07:23 /dev/rmt/0m

from:

ds1-nhdr:root:/->#ls -l /dev/dsk/c0t3d0
brw-r----- 1 bin sys 31 0x003000 Jun 2 1998 /dev/dsk/c0t3d0

to determine which device is failing?

Thank you,

Hi Randy:

The first two digits of the device are the major number. Hence, device 'cd030000' would be a major number 0xcd or decimal 205. That's tape.

Try lsdev -C 205 , that should give you what device is.

205 is decimal value of hex cd , from your lbolt output cd.

..oops..I mean lsdev -c 205. On my machone it looks like a tape device.

Thank you! That's exactly what I was looking for.

Whatever device this points to, the lbolt points to a serious problem.

If it currently works, it won't for long. Either cabling or termination, or the device will have to be replaced. Make arrangements.

Exception. If you recently did an equipment swap like a hot swap of a drive, you will get an lbolt until next boot.

Doesn't look from the earlier info thats what happened.
