Getting the correct device from the lbol error

1. Get the "dev:" entry from the lbolt:

# dmesg | grep lbolt | grep dev: SCSI: Abort -- lbolt: 18346341, dev: e7015000, io_id: 122e9a3 SCSI: Request Timeout -- lbolt: 18351441, dev: e7015000 SCSI: Abort -- lbolt: 18351441, dev: e7015000, io_id: 122e9be SCSI: Request Timeout -- lbolt: 18356641, dev: e7015000 SCSI: Abort -- lbolt: 18356641, dev: e7015000, io_id: 122e9cf SCSI: Request Timeout -- lbolt: 18362141, dev: e7015000 SCSI: Abort -- lbolt: 18362141, dev: e7015000, io_id: 122e9e0 SCSI: Request Timeout -- lbolt: 74105435, dev: 1f000000 SCSI: Abort Tag -- lbolt: 74105435, dev: 1f000000, io_id: 4ead34

Here we have two:

1f e7

2. This is the major number of the device in question. Convert the first two digits of the device from hex to decimal:

# printf "%#d\n" 0x1f 31

3. Find out what driver this major number is. It tells us the type of device:

# lsdev 31     Character     Block       Driver          Class        31          -1         fcd             fc       188          31         sdisk           disk

So, this is probably a disk !

4. Find the device file entry from the remainder of the lbolt error:

SCSI: Abort Tag -- lbolt: 74105435, dev: 1f000000, io_id: 4ead34

This is the minor number for the device that is failing.

1. Block device:

# ll -R /dev/ | grep 31 | grep 0x000000 brw-r----- 1 bin sys 31 0x000000 Jul 15 16:25 c0t0d0

Or:

2. Character Device:

# ll -R /dev/ | grep 188 | grep 0x000000 crw-r----- 1 bin sys 188 0x000000 Oct 11 07:15 c0t0d0

5. Find the Hardware Address:

# lssf /dev/dsk/c0t0d0 sdisk card instance 0 SCSI target 0 SCSI LUN 0 section 0 at address 0/0/0.0.0 /dev/dsk/c0t0d0

6. Find the type of device:

# diskinfo /dev/rdsk/c0t0d0 SCSI describe of /dev/rdsk/c0t0d0: vendor: DGC product id: C2300WDR1 type: direct access size: 4102875 Kbytes bytes per sector: 512

So, we have a disk at hardware address 0/0/0.0.0, device file /dev/dsk/c0t0d0
