This is exactly how I set mine up (minus SAS). I have 3 x 2TB SATA drives set up with the same partition map on each drive: a 64GB primary solaris partition, and an "other" partition of the remaining part of the disk. The 64GB partitions (slices: c2t0d0s0, c2t1d0s0 & c5t0d0s0) are a three way mirror, and the remaining part of the 2TB drives (c2t0d0p2, c2t1d0p2 and c5t0d0p2) is in Raid-Z. 

I think I actually started out by installing the OS onto a spare 64 GB partition, then added the others to the mirror and have since removed the original 64GB drive. While this might not answer your installer question, at least it's a configuration that can work and installing on another drive may provide an alternative for you.

Best,
Matt.

I would like to have a solaris2 fdisk for the whole of the disk but when it comes to the format partitions I would like to have about 10 to 30 Gig at the start of the disk for the os; then setup another slice for the data to be shared, however the installer only lets me set one value. I have tried setting up the partitions first by hand but there doesn't appear to be an option to leave the fs intact and point it at a slice (format partition). Hope this makes sense. Any ideas..?
