This will work only for sw raid. In the hardware raids I have come across the array is presented as a monolith device e.g. /dev/sda > If its an individual disk, I don't know of any direct, linux native > way of finding it.

If it is on it's way out, there will be timeouts or read errors. But detecting such errors (OP) from a remote location. Hmmm, may be some kind of SNMP report? -- Arun Khan -- http://mm.glug-bom.org/mailman/listinfo/linuxers
