Hi all,
I have received the following SCSI reset/lbolts on my K460 this morning (running 11.11)....

SCSI: Resetting SCSI -- lbolt: 255632514, bus: 3
SCSI: Reset detected -- lbolt: 255632514, bus: 3
I have attached a full ioscan.
Can anyone confirm please how i identify what is actually hanging off bus 3 ?
Am i correct in thinking a....
"ioscan -fnC ext_bus"
and then its the 2nd column that shows the bus ??
So, in my case, it would be 8/12 ??
There are no other system problems so this seems an isolated error and to my knowledge everything is terminated correctly.
Many thanks in advance for any replies.

Sean,
The key element to look for in here is:
bp->b_dev: cd0330c0
So to decode this:
The first 2 bits (cd) represent the major number of the device file - so cd is hex for 205:
#lsdev | grep 205
205 -1 stape tape
So it's a tape drive...
The next bits are Bus/Target/LUN as in BBTL in hex, so 0330 is
c3t3d0
Which looking at your ioscan output is the tape at HW path 8/12.3.0 (/dev/rmt/8m)

Re: SCSI resets - How do i identify what hangs off bus 3
Hi Duncan,
Many thanks for the clarification of identifying which actual element on 8/12 complained.
