Problem:
How do I locate a specific disk in the Sovereign 4897 Series?
Details:
Disk device names in Linux (ie: sda, sdb) are not guaranteed to be consistent between reboots. In addition, the order of assigned names may have no logical relationship to the slots of a storage enclosure. This can make locating the proper device for removal from the chassis error prone.
To ease this task you can use the 'blink' utility available at the following url:
ftp://ftp.aslab.com/pub/utility/blink"
For example, to find device sdc in the enclosure:
# ./blink sdc Turning on locate LED: /sys/class/enclosure/6:0:1:0/Slot 10/locate
The slot containing sdc will then blink it's LED. To turn off the LED, simply run the command again:
./blink sdc Turning off locate LED: /sys/class/enclosure/6:0:1:0/Slot 10/locate
The blink utility works for SAS drives installed in an enclosure with a SAS expander connected to a non-raid storage controller such as the LSI 9207 series.
