harddrive lights

[Ratzie]

I need to source out what hard drives are what on my HP 11 system, how do I get the lights to turn on on the hard drive.

I heard that you can use dd?

Was there ever a way in sam?

I usually do something like this:

# dd if=/dev/rdsk/c?t?d? of=/dev/null bs=4096K

Let the command run then go look for the drive that has a light that is flashing like crazy. Hopefully this will be done when the system is not busy as you don't want ALL your drives flashing because people are working.

Once you know what drive that one is, do a CTRL-C to break out of it and go to the next drive and repeat.

dd if=/dev/rdsk/cXtXdX of=/dev/null

Depends what you're looking at.

If you're talking about an external array, then the previous suggestions are best. Just make sure that you don't mix up the 'if' and 'of' parameters :-)

On newer (rp series) systems, the disk hardware path is stamped on the chassis, so you can work out whats on the internal disks at least by using ioscan.

If you're talking about XP storage, then thats a different ball game again.
