The drives are arranged in four groups of eight drives in RAID6 and one group of four drives in RAID5.  These five RAID groups are set up as iSCSI targets on the Ubuntu system.  There are two of these SuperMicro shelves.  So, there are ten LUNs available by iSCSI to OpenIndiana.  The tank is created with one VDEV for the ten LUNs.

OI/ZFS won't see the disk chassis or disk types at all, all it sees are the iSCSI LUNs exported by the Linux boxes.

So you mentioned you're using Ubuntu 10.10. What iSCSI target are you using? which exact version? 
What's your iSCSI target configuration? 

Are you using iSCSI multipathing from OI ? Did you try without?
