Richard,<br>
Thank you very much for this! Unfortunately, since the system
has been rebooted all the disk error counts are back to zero. My
system didn't have the sasinfo command, do you know what package I
need to install? The echo::mptasas command worked.<br>

<div class="">Hi CJ,<br class="">
I'm away from my notes at the moment, but know that an
mptsas instance's reported target number is not the same as
the sd driver instance number. The most expeditious way to
cross reference is to use sasinfo or, failing that, <br

If that still doesn't narrow the field, look at the per-disk
error counters: <br class="">
iostat -E<br class="">
<br class="">
Note: resets are tricky and you can be sure sd is trying to
reset devices to wake them up. <br class="">

More later, when I get back to the office...<br class="">

Hello,<br class="">
Need some help identifying physical disk on my system.
My system got hung and last thing in the /var/adm/message
file before the crash is follows:<br class="">

Then using the command "cfgadm -alv" shows that the
/pci@0,0/pci8086,340c@5/pci1000,3020@0 is the controller
in front of all the disks. The output above does say
"Target 48", I'm hoping that is the disk target so would
be the one listed in the cfgadm command here:<br class="">
<br class="">

<br class="">
Would this be the disk being reported in
/var/adm/messages?<br class="">
