Hard disk replacement
Hi all,

I need some help with a RHEL 4 on a Sun Fire v65x machine.

Some of the disks is damaged or has a hardware issue. This disk is connected to a hardware raid.

The problem is that I don't know what is the brand, model and capacity of the disk.

I've read the raid manual, but says that you can't unplug the disk if the OS is on.

So, here cames my question: how could I get this info withouth stopping or rebooting the server? It's an oracle production server.

Thanks,

Alex.

Probably somewhere in /proc.

I found a site on Google which claimed that RAID drive info is in /proc/mdstat.

Check it out. If that doesn't help, this will hopefully be enough for you to dig a little more in /proc and on Google to find it.

hi ShanMilo,

I'm sorry to say there's no helpful information on /proc/mdstat

I've done a lot of dig into google, as well as on sun and red hat, but nothing useful.

I'm a returning sys admin to linux, and need to refresh my knowledge.

Any other ideas?

Thanks,

Alex.
