and in a server one of the hard disk had failed. Then how do we find which hard disk

Individual disks or hardware RAID?

what is the
command in AIX?

If the disk is a member of a raid array, you can do a cat /proc/mdstat
to know its health.
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.

True. This was a typical case of me thinking of complicated solutions
and ignoring the most basic and simple one. :-)
Does an amber light on the disk always trigger an alert in the syslog?

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 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?

For hardware RAID, you could use the RAID manager software. IBM's Raid
Manager disks have RPMs for RHEL. You would have to hunt a bit to find
the solution for other vendors.
