HP DL380 Raid Controller Disk issues.

Today for the first time in my life I had troubles setting up a normal FreeBSD machine due to the geometry of the disk. The machine has a Raid 6i card in it, and there are four 147Gb disks in a RAID5 configuration.

The device gets detected as:

da0: 420029MB (860220400 512 byte sectors: 255H 32S/T 65535C
Fdisk complains about it:
A geometry of 105419/255/32 for da0 is incorrect.
and picks:
DISK Geometry: 53546 cyls/255 heads/63 sectors = 860216490 sectors (420027MB)

Installing FreeBSD on that geometry goes without a problem. But at a reboot, it doesn't work anymore. Pressing F1 for FreeBSD at the bootmanager doesn't work, it just beeps.

Luckely Darius on #bsddev knew how to resolve this:

<Darius> also, can you get to the loader prompt on the CD after you have installed and type..
<Darius> unload
<aDrius> set currdev=disk1s1a:
<aDrius> boot -s
<Darius> then run boot0cfg /dev/da0
It works!
