Thanks to Mark Wiederspahn, Mike Ekholm and Kevin Smith for their help.

The procedure is this (MW):

To start with, from this page is (http://www.sun.com/storage/san/)
is a link to the sun drivers:
http://javashoplm.sun.com/ECom/docs/Welcome.jsp?StoreId=8&PartDetailId=StoreEdgeSw-4.0-G-F&TransactionId=Try

Download the "Install_it Script SAN 4.4.1, English" under optional
products, and install that software.

The sun drivers kind of suck because they require 10 packages
and 15 patches to be applied in a specific order.  The install_it script
will install those packages/patches in that order.

Once the products are installed, reboot and run cfgadm -al and see if 
you see your disk.

#cfgadm -al

(apologies for wrapping. the FC SAN stuff is on c3)

If cfgadm sees your adapter/disk, run cfgadm -c (fiber_ctrl) to pickup
the disk.

(TH) Also add to /kernel/drv/sd.conf

#
# added for SAN
#
name="sd" class="scsi"
   target=0 lun=1;
name="sd" class="scsi"
   target=0 lun=2;
name="sd" class="scsi"
   target=0 lun=3;
name="sd" class="scsi"
   target=0 lun=4;
name="sd" class="scsi"
   target=0 lun=5;
name="sd" class="scsi"
   target=0 lun=7;
name="sd" class="scsi"
   target=0 lun=8;
name="sd" class="scsi"
   target=0 lun=9;

to scan the LUNs designated to SAN space.

boot -r

format will show :

AVAILABLE DISK SELECTIONS:
        0. c1t0d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
           /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cf6f1b1f,0
        1. c1t1d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
           /pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w21000004cf6efe8d,0
        2. c3t200800A0B813180Dd3

           /pci@8,700000/SUNW,qlc@2/fp@0,0/ssd@w200800a0b813180d,3

So, we're off.

Only the card has two ports and we need failover/redundancy.

Now I believe this can be done one of two ways :

1) Sun Traffic Manager - does the multipathing and fail over. Costs money.
2) Qlogic firmware card can, according to a colleague, appear as a 
single port and it deals with the multiple paths and failover on the 
card. This is a Sun branded Qlogic card.

Any pointers?
