D1000 and ZFS

Dear managers,

we purchased a used D1000 unit and connected that via an appropriate
SCSI HBA to a SF 280 R. We want to build a ZFS pool of the 12 SCSI
disks and put /home on the D1000. Both machines (D1000 and 280R) are
powered up: I get

-bash-3.00# ls -l /dev/rdsk
total 48
lrwxrwxrwx 1 root root 46 Dec 28 18:47 c0t6d0s0 ->
../../devices/pci@8,700000/scsi@6/sd@6,0:a,raw
lrwxrwxrwx 1 root root 46 Dec 28 18:47 c0t6d0s1 ->
../../devices/pci@8,700000/scsi@6/sd@6,0:b,raw

lrwxrwxrwx 1 root root 46 Dec 28 18:47 c0t6d0s7 ->
../../devices/pci@8,700000/scsi@6/sd@6,0:h,raw
lrwxrwxrwx 1 root root 74 Dec 28 18:47 c4t0d0s0 ->
../../devices/pci@8,600000/SUNW,qlc@4/fp@0,0/
ssd@w21000004cfef623f,0:a,raw
lrwxrwxrwx 1 root root 74 Dec 28 18:47 c4t0d0s1 ->
../../devices/pci@8,600000/SUNW,qlc@4/fp@0,0/
ssd@w21000004cfef623f,0:b,raw
...

now but am not sure whether this c0t6d0s0 is one of the 12 SCSI disks
inthe D1000. Actually I expected 12 disks to appear here. What would be
my next step to see the SCSI disks? If I call format I only see the two
fibre channel disks built into the system:

-bash-3.00# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
        0. c4t0d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
           /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cfef623f,0
        1. c4t1d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
           /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cffd1290,0

I will google for ZFS documentation now but I assume I first have to
make the disks avaiable to the system (actually get the disks started;
they are not spinning yet) before thi swill lead me anywhere.

Hints are greatly appreciated!

Thanks,

   Andreas
