OK, but I'm a bit lost.  Maybe to unskilled to understand.  Lets start
what do you mean by 'ZFS should find the pools'

The live media must have drivers for all my disks since I've installed
them from the live media.

Are you saying that `zpool list' should 'see' them?

When booted from the install media iso:
zpool list shows .. well not much:

  jack at openindiana: ~$ sudo zpool list
  no pools available

Won't I need to mount a disc that has the installed os on it first?

[...] snipped the handy detailed commands ... thanks

I must need a more basic step in here somewhere.

Looking from the install media with 'format', my discs are 'seen': 

$ sudo format 

  AVAILABLE DISK SELECTIONS:
         0. c4d0 <Unknown-Unknown-0001 cyl 4092 alt 2 hd 128 sec 32>
            /pci at 0,0/pci-ide at 1,1/ide at 0/cmdk at 0,0
         1. c4d1 <Unknown-Unknown-0001 cyl 4092 alt 2 hd 128 sec 32>

            /pci at 0,0/pci8086,2829 at d/disk at 3,0

The os disks, (setup as a mirrored rpool):
  0. c4d0
  1. c4d1

Not sure what is unknown about them... they are IDE discs. and I've
been running 151a7 on it for over a week now.

2 and 3 are zpool hp1
4 and 5 are zpool hp2

Bother are mirrored 2 disc zpools

But I'm still not 'getting' how to make any of this available to
'jack' on the install media?
