At first it wasn't working. I had to update from firmware 2.xx.xx.xx to 5.00.13.00 and it started working right away. Something I noticed is that with SATA disks the LEDs blink when there is activity only. With SAS disks they are always lit and turn off when there's activity. >> In case anyone wants to understand how the device names works, see >> this excellent presentation: >> >> http://www.jmcp.homeunix.com/~jmcp/WhatIsAGuid.pdf >> > > Even if the LEDs lit up, how would this help determine which drive is which? > The only identifying features of the drive are the slot and serial number, > but OpenSolaris doesn't seem to know that information. As suggested by James, I'm doing the following: # ls -lart /dev/dsk/c5t5000C50020C79CC7d0 lrwxrwxrwx 1 root root 49 Jun 9 10:01 /dev/dsk/c5t5000C50020C79CC7d0 -> ../../devices/scsi_vhci/d...@g5000c50020c79cc7:wd # prtconf -v /devices/scsi_vhci/d...@g5000c50020c79cc7 | egrep -A1 serial name='inquiry-serial-no' type=string items=1 dev=none value='9WM0JCZN0000C029JS2U' # sas2ircu 0 display | grep -B7 -A2 9WM0JCZN Enclosure # : 2 Slot # : 18 State : Ready (RDY) Size (in MB)/(in sectors) : 1907729/3907029167 Manufacturer : SEAGATE Model Number : ST32000444SS Firmware Revision : 0005 Serial No : 9WM0JCZN Protocol : SAS Drive Type : SAS_HDD # sas2ircu 0 locate 2:18 on LSI Corporation SAS2 IR Configuration Utility.
