We had a problem tonight with some blades not booting from their internal HHDs. It turns out that in order to boot from internal HDD you need to disable the planar daughter card slot one to free up the IRQ for the HDD to boot.
When configuring ESX (or whatever OS) you need to enable the card for the HBA utility to be accessed (but disable it again after the config)
Isn't life fun :-)
UPDATE: Doing this allows it to boot but then it can't see the SAN LUNs!! Ooops.
UPDATE: To fix this just reset the HBA BIOS to factory settings, even though they look identical to working ones.
