How to detect slot for a disk

[Andreas Bechtle_1]

Hello,

I've several D380 with Hardwareraid and Redhat 2.1. There are 6 internal disk, each with a mirror so in the OS I see my 3 disks.

My question: How can I detect in which slot a disk is?
I.E. I want to remove /dev/cciss/c0d1 (after umount etc), how do I know which 2 disks to pull out off the server? I need a command which says "/dev/cciss/c0d1 are in Slot X and Y". Any ideas?

Best Regards

Andreas

You could use dd to generate read activity for the disks, so, use dd and check the led activity, like this:

dd if=/dev/cciss/c0d0 of=/dev/null
dd if=/dev/cciss/c0d1 of=/dev/null
dd if=/dev/cciss/c0d2 of=/dev/null

Hi,

I knew this trick but I did not trust the results. Just did not want to believe the OS is on a RAID5, but it is true. =8-O

However, you got the points for the correct answer ;)
I also found another way: With Insightmanager you can get this information. So there must be a way to get this online.

Have a nice day
