Locating certain physical disks
Hi, is there a command to turn on an LED to locate a certain disk? I have many disks attached on this server and some failed. Looking at the front side LEDs on disks, I couldn't which ones are bad since the ones with green LED on match neither the number of good nor bad disks.
Below is my ioscan -kfnC disk output.
5 bad drives that I need to identify are: c0t8d0, c1t9d0, c2t0d0, c2t2d0, and c2t3d0, which don't appear in this output, though.
Any help would be greatly appreciated. Thanks.

Re: Locating certain physical disks
hi yssong,
you can run read-only test with a dd command to check the location of the disk. the activity will turn on the led on the disk. e.g.
#dd if=/dev/rdsk/c0t8d0 of=/dev/null bs=1024k
remember to use of=/dev/null and no typo error in the command.

Re: Locating certain physical disks
The commands and ability to turn a locator on depends on the used hardware.
Some disk chassis support this.
Commands may be available in SAM.
What disk chassis do you have?
For most chassis the SCSI IDs are fixed, so if you know the ID, you will know the slot too.
Hope this helps!
Regards
Torsten.
