What do you mean by "not working"? OS not running, not booting, not accessible, some software not running, .... ?

There are tools like Nagios that allow management of large server parks. The answer is probably there.

not working in the sense , it stopped from regular functions/Malfunctioning or you can say not accessible.

Just i wanted to know which server is malfunctioning. i'm wondering, is there any command to find out that sever information.

You might be able to use nmap to try to determine if the host is up

From documentation :-)

Usually the documentation on the cluster configuration would tell you where "server 55" is physically located...

You might need to know that depending on the design (I've seen things like having hostnames of "server55") and even having the IP number won't help you if you need to go a plug it back in/replace a fuse/... Sometimes a KVM will not help as all you may get is a blank screen.
