Individual disks or hardware RAID?
If the disk is a member of a raid array, you can do a cat
/proc/mdstat to know its health.
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. Your hardware vendor might provide some
daignostic software that can be run without rebooting the system.
If the disk does not show up in "fdisk -l " certainly rip'd. This
is the easy one. 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?
