[CentOS] CentOS on IBM Bladecenter HS21

I have CentOS 5.2 installed on two of the afore-mentioned blades.
I've noticed that the OS started to crash lately (kernel panic) and I've
been assigned the task to troubleshoot this issue.

I would like to know what is the best way of recovering the kernel
dump after the OS crashes.

I know there are two software implementations that would enable me
to do this, kexec and 'crash' , redhat's own implementation that allows
you to pust the dump via network to a remote machine.

What would be the best thing to do at this point?
