I'm trying to set up a raidz pool on 4 disks attached to an Asus P5BV-M
motherboard with an Intel ICH7R. The bios lets me pick IDE, RAID, or AHCI for
the disks. I'm not interested in the motherboard's raid, and reading previous
posts, it sounded like there were performance advantages to picking AHCI.
However, I am getting errors and I am unable to create the pool. Running format
tells me
AVAILABLE DISK SELECTIONS:
0. c12d1 <DEFAULT cyl 19454 alt 2 hd 255 sec 63>
/p...@0,0/pci-...@1f,1/i...@0/c...@1,0
1. c13t0d0 <drive type unknown>
/p...@0,0/pci1043,8...@1f,2/d...@0,0
2. c13t1d0 <drive type unknown>
/p...@0,0/pci1043,8...@1f,2/d...@1,0
3. c13t2d0 <drive type unknown>
/p...@0,0/pci1043,8...@1f,2/d...@2,0
4. c13t3d0 <drive type unknown>
/p...@0,0/pci1043,8...@1f,2/d...@3,0
The first disk is an IDE disk containing the OS, and the 2nd four are for the
pool. Then
# zpool create mypool raidz c13t0d0 c13t1d0 c13t2d0 c13t3d0
cannot label 'c13t0d0': try using fdisk(1M) and then provide a specific slice
When doing this, dmsg says:

I find reports from 2006 that the ICH7R is well supported, so I'm not sure what
the problem is. Any suggestions?
