Failure to probe Intel Cougar Point in ESX?

[Darren Reed]

At long last a VT-d capable replacement CPU arrived for my HP MicroServer
Gen8and I thought "cool, now I can pass through the hard drives!". Life
is so simple when you're just a spectator. To pass through only the four
hard drive bays on a Gen8 Mircoserver requires either having a dedicated
SAS/SATA/RAID card that connects only to them or changing the BIOS config
to do "SATA Legacy". In SATA Legacy the HP Microserver Gen8 presents two
SATA controllers to ESXi: 1*4 Port, 1*2 Port. At this point it looks to
be simple: just tick the box for the 4 port controller to be in pass-
through mode and you're done. Not quite. Yes, putting the 4 port SATA
controller into pass-through mode allows it to be passed into FreeBSD
as a PCI device but when FreeBSD gets it, well, it comes in the diet
version - without any hard drives attached. This can be seen in the
extract from /var/log/messages below - disks are found and attached
that are presented as regular VMDK files but nothing is discovered
underatapci1 beyond ata3 and ata4. If this were NetBSD I'd suspect that
there was a missing "wd* at ata*" or similar but FreeBSD doesn't work
like that so I'm a bit mystified.
