[SunHELP] StorEdge 3120 connection in HA environment:

[Yang, Chi-Tai]

I am using VCS 4.1 - 2 hosts, 2 x StorEdge 3120 (each with 2 disks):
3120 (3000 Family ) release note does not have clear indication of how the
SCSI wiring shoud be.
(at least this one:
http://docs.filibeto.org/products-n-solutions/hardware/docs/pdf/816-7956-11.p
df)

I have tried many vaiations, the best I can come up is (other than root disk /
root mirror)  each node sees c1t8, c1t9.
Ideally each node should see c1t8, c1t9, c?t12, C?t13......

         +-----------+  hostA
         | ---   -2- |  (dual scsi)
         |    -1-    |  (on board)
         +-----------+
   +-----------------------+
   |  -x-  -1-  -4-  -x-   |  3120 StorEdge  (array 2)  (DIP switch on left
side, thus should appear t12, t13).
   +-----------------------+
   +-----------------------+
   |  -y-  -3-  -2-  -y-   |  3120 StorEdge  (array 1) (DIP switch on right
side, thus shows t8 and t9)
   +-----------------------+
         +-----------+  hostB
         | ---   -4- |  (dual scsi)
         |    -3-    |  (on board)
         +-----------+

Remarks: 1 wire to 1, 2 wire to 2, x wire to x, etc.

I even tried "chaining" like this:   (it's even worse).
   +-----------------------+
   |  -x-  -1-  -4-  -y-   |  3120 StorEdge  (array 2)  (DIP switch on left
side, thus should appear t12, t13).
   +-----------------------+
   +-----------------------+
   |  -x-  -3-  -2-  -y-   |  3120 StorEdge  (array 1) (DIP switch on right
side, thus shows t8 and t9)
   +-----------------------+


Does anyone has a working setup or suggestion?

Thanks.
