Hello,
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.
I've used kdump to troubleshoot these types of issues in the past:

Once you have a core file, you can use crash and company to figure out what caused the kernel to panic.
