How blink a drive with SAS2IRCU on a IBM M1015 controller??

[mbalsam]

I need to identify a bad drive on a IBM M1015 controller. I read that the sas2ircu command would do the trick.

I got the the Serial No From STORAGE > VIEW > DISKS

Ran "sas2ircu 0 DISPLAY" to list all of the serial numbers and enclose numbers on controller 0.

The disk with the matching serial number was enclosure 1 slot 2

so i ran "sas2ircu 0 LOCATE 1:2 ON".

I expected one light to blink. But all of the drives on that controller blinked???

Any ideas?

It's rather hard to approach the issue if you don't even tell us what kind of backplane you're using.

Chassis lights are very poorly standardized and a pain to get to work.
A much simpler option is to use dd to exercise the drive. Say, dd if=/dev/da7 of=/dev/null. CTRL+C to stop it once the drive has been identified.

The most reliable way is to label the drive carriers before you put the drives in the chassis. Mark the last 4 digits of the SN on the label. It is usually unique enough to identify the drive. I have a chassis where the drive activity lights don't work, and another that has no lights at all, so this is the only way that works every time.
