Both user groups are very happy.

Hi Dave,
I can help. I have to jump in, now. I've done SSA for a very long time
and
the answer is simple:
(1) Power off both systems.
(2) Disconnect all the cables from each of the two systems and
from the
SSA drawers. At his point you're looking at a bunch of cables in front of
you along with two systems that are completely powered off.
(3) On SystemA, connect one end of the SSA cable to port A1 on the
SSA
adapter on SystemA, and connect the other end of the SSA cable to port 1 on
the SSA DrawerA.
(4) Now grab another cable, and connecty one end of the other SSA
cable
to port A2 on the SSA adapter on SystemA, and connect the other end of the
SSA cable to port 16 on SSA DrawerA. This completes the steps for SystemA.
Now you're off to SystemB.
(5) For SystemB, complete steps (3) and (4). I know you didn't
power on
the systems yet! Did you? I hope not.
(6) Now power on SystemA. Do a "lspv". Do you see your 16 disks?
OK.
Great, now off to SystemB.
(7) Repeat step (6) for SystemB.
(8) Any questions?
NOTE: If you don't see all 16 drives on each system then let me know,
because now we're talking about physically pulling out the BY-PASS cards on
the SSA drawers to reset the jumpers! Oh dear. But it's very easy :)

I read the docs you pointed to but I am still confused.
I'll try to make it a little easier:
I have one system - System A (IBM 44p) with one SSA adapter (4 ports)
(From the back of the unit)
System A
SSA Adapter
Ports
A B C D
I have one SSA (Model 713-020) drawer with 16 9GB disk drives (From the
back
of the unit)
Ports
Ports
4
1
*

5 DRIVES 16
8
13
9
12
(The * are a pair of jumpers which are open)
All I want to do is to connect SystemA to the SSA drawer so it sees all 16
drives.
All disks are empty (no data)
Help?

Dave,
Its been a while since I have worked with SSA, so perhaps there are others
better qualified. Don't mean to sound cold here, but there are many pieces
of information that you didn't include to even know how to formulate an
answer for you.
If you could describe what type of configuration you want as an end
product,
for Eg.
-(2) standalone systems, each with (1) drawer of 16 9GB drives [no
relationship between the 44p and F80 when complete] or
-(2) systems that can each see both drawers for redundancy
Do all 32 disks in the large VG have data on all the drives? If so, you
need
to get the data free from the 16 you want to take and then reduce them out
of the VG before you disconnect them.
You might want to include some lsdev -Cc disk, lsvg -p BIGVG (describe
which
disks you want to keep on the 43P), etc
For starters, a few references that have helped me in the past.

The 7133-020 Service Guide was particularly helpful for cabling.

Subject: SSA configuration help!
Before I dig myself a hole I won't be able to get out of......
I need some help with configuring SSA
Right now:
System: 44P Model 270
4 Port SSA card
2 separate SSA drawers (Model 7133-020) with 16 9GB drives in each
Both drawers are hooked up to the 44P
> From the back of the system:
2 cords go to the top right 2 ports of the one drawer
2 cords go to the top right 2 ports of the second drawer
One Large volume group includes all the drives (No RAID)
What I want to do:
I have a F80 with a 4 port SSA card
I want to hook up one drawer to the 44p and one drawer to the F80
Can anyone help or point me in the right direction?
I've already wasted a day trying to do this myself...
