Finding hardware issue in a solaris machine

Hi folks,

In a running solaris machine (lets assume its critical server), how can I find whether is it got any hardware issue or any hardware (say harddisk) about to fail?  Is there any diagnostic tool available in Solaris which will facilitate to find the hardware issue advance in time, by which we can ensure the 100% uptime.


Thanks,
Ashok

Use the following command to check the information on CPU, RAM, PCI Cards etc. You dont even need to be root to execute this command:

/usr/platform/`uname -i`/sbin/prtdiag

I thank each one of you for giving valuable inputs for this issue. I moved on to a new company where I don't have access to any servers till now. Hence I couldn't try all your solutions BUT will do definitely once I get the access.
