Ok I found the problem with 0x06, one disk was missing. But now I got all my 
disk and I get 0x05.:

There is no scsi the disks, because those are virtual disk. Also for anyone who 
are interest, I wrote a little program to show the properties on the vdev.:

http://www.projectvolcano.org/zfs/list_vdev.c.

Here is a sample output:
bash-3.00# ./list_vdev -d /dev/dsk/c1t12d0s0 
Vdev properties for /dev/dsk/c1t12d0s0:

So my question, is there a way to really know why I got IOE (0x05)? Is there a 
way to know in the debugger? How can I access it?
