HP will issue a customer advisory for RH EL 5 Xen. HP has certified and will support these servers listed below with the following caveats:

Wonder who uses those anyway, with proprietary modules around this is
one of the first things to point to when the kernel behaves strange.

Getting aware of disk-failure in HP-servers was good enough for us
and only needs tools operating in userspace.
Did someone try to run array-info in a dom0 running on HP-hardware?

You've noticed that?

I'm going through this now as part of negotiating some co-location services. They couldn't *imagine* that I'd rather have backup OS images scattered around multiple servers than burning half of my available disk using RAID1, and couldn't imagine using SNMP monitoring of overall services rather than these familiar integrated tools. It's leading to a lot of... negotiation.

It's handy when you only have a very few staff, and a 99.9% uptime SLA, to get the reports of hardware outages rather than poking the OS's. But given that development and QA work is so likely to slap down servers until a year or two after the software is stabilized and in use, it just seems a waste of time. Orient your support around fast swap-in capability, easy redeployment, and regular backups instead.
