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?
I don't have any experience for how to debug this. But I have CentOS 5 running fine on the same kind of Blades. I have about 25 of them and have seen no crashes. What kernel are you running ? Did you upgrade the firmware on the Blades to the latest version ?
