How to find the disk that crashed on the disk trays??

[rvent]

Hello,

I have a bad drive and i need to replace it, however, i have 2 HP Disk System 2120 and i cant tell which drive is the one i need to remove.

I certainly dont wanna remove the good one and make all hell break loose...

Any ideas on how i can identify the disk??

Thanks!

You can get the h/w path from ioscan, so you know the slot where the HBA is installed.

Now you can follow the cable ...



But I prefer to turn the activity LED on for the *good* disk (using "dd"), so you know you need to pull the other disk ...

Well folowing the cables is a bit confusing since we have 2 trays that connect to 2 HP3410 so it can get confusing doing that.

How would i use dd to turn on the light on the disk??

Thanks

I assume you mirror between the both enclosures.

From vgdisplay get the device file of the *good* disk, then do

# dd if=/dev/rdsk/c1t1d0 of=/dev/null

where c1t1d0 is the GOOD disk.


You will see the activity LED steady on.

I assume you already know the slot of your bad disk - so now you know the bad disk.
