I hoped I had the newet version of the firmware on the HBA.
monosan:~ # cat /sys/class/scsi_host/host6/version_fw 
01.24.01.00
monosan:~ # cat /sys/class/scsi_host/host6/version_mpi

> I would like to point out there is a firmware request for sending SEP request, for instance setting LEDS.   Here is a copy of the structure.  We call this function to set LED when there is SMART errors (for non-raid devices).  For RAID, the firmware handles it.   Is this what your looking for?

I'm not firm enough with scsi to understand all your words. But the problem I have is not that something doesn't work. It works with 2.6.25.
I can get the LEDs to blink. I can choose which one should do. I simply don't know which one it should be.

The problem is, I wanted to simultate a faulty drive without being one faulty.
Therefore I choosed a (working) disk to be faulty by its mutlipath-name: dm-9
Then I found out which disk it is in sd? notation. Then I read the serial number of this disk with the smartmontools.
Now I want this LED of the bay containing the disk with this serial number to blink. But I can't find out which LED matches which serial number of the containing disk.

I know my english is not the best. Ask and I try to explain again.

Regards
Lars
