We have One SuperMicro server and on that we installed RHEL 5.6 64 bit but after installation it hangs at STARTING UDEV .

Any ideas what is stopping it to start and proceed.

Try starting in single user mode. See link – midnightsteel Nov 8 '12 at 19:52
Once you get into single user mode check the messages log for errors that might be causing the issue, then update your question with any pertinent information – midnightsteel Nov 8 '12 at 19:59

Remove quiet from the kernel command line and you should get enough output to see the cause of the hang.
