what u think ??? F4

We think you should spell out your words, and quit posting that text-speak garbage that's against LQ rules.

And since you're using RHEL5 on a SAN, you've got support from both RedHat and your SAN vendor. They could figure this problem out much faster than we can here. Mainly because there are too many variables to post/check here. Could be any one of a thousand things.
