I had a CentOS 5.5 Xen standard virtualization install lockup on

I have to head to the site (with a fractured ankle), but reports
indicate that it is at
- (none) login:
which only returns back to itself after a user login at console,
including root.
- the local user says, though the monitor speed was too fast that it
is failing to find its mounts OR that the disk reported errors.
It is on a dmraid (I know, please don't flame me).
There is some critical information on the drives that did NOT backup.
I need a list of tools and ideas to have a checklist to try and
resurrect this machine.
Of course I will go with
- Live CD
- CentOS 5.5 install.
- Hard drives.
I would appreciate any procedural methods to go about this and try to
resurrect this machine.
Hmm.. boot log would be good, then it'd be obvious what's wrong.
Try using a serial console to capture the Xen/kernel messages?

Other than that.. did you check redhat bugzilla if there's some dmraid
related regression on 5.5 ? Or maybe some other regression..
