syslog SCSI:Request Timeout

[Joseph Primm]

I'm looking for information on how to interpret the following (how do I cross the dev: number and or determine which device is generating this, and is v11.0):

vmunix: SCSI: Request Timeout -- lbolt: 5166392, dev: 1f081100
vmunix: lbp->state: 4020
vmunix: lbp->offset: ffffffff

[Brian M. Fisher · Accepted solution]

You can use the following information to determine which device
generates the lbolt/timeout errors:

1f 02 6 0 00
__ __ _ _ __
| | | | |
major# | target | flags
| |
bus# lun

Per this information:

- major# (1f) is 31 in decimal, and major number 31 should be
sdisk on your system.

- bus# (02) is the card instance number to which the device is
attached.

- target (6) is the device's scsi id.

- lun (0) is the device's logical unit number.

Therefore, this device maps to /dev/dsk/c2t6d0.
