Well, I think you can't do that.....
on every side of a peer link you can have ONE and only ONE CF. In your
case,
you have to add a second peer link for new sysplex. Otherwise, you have to
rebuild your configuration, using a couple of peer links (no redoundancy)
for both PLEX1a and PLEX1b.... reusing your second peer couple for new
sysplexes...

Hope this helps.

Subject: Shared ICP between 2 SYSPLEXES

Hello,
I have the following question :

We have the following configuration :

2 CPC's , on each one 2 LPARS,  one CF and One MEMBER of SYSPLEX1.
both CF's are connected to the members of the sysplex of the
other CPC with  a pair of  ICP connections .

  CPC1                       CPC2
+--------+                 +--------+
|        |           icp   |        |
| PLEX1a |------+  +-------| PLEX1b |
|        |      |  |       |        |
|        |      |  |       |        |
+--------+      |  |       +--------+
|        |      +--|-------|        |
|  CF1   |---------+  icp  |  CF2   |
+--------+                 +--------+
|        |                 |        |
|        |                 |        |
|        |                 |        |
|        |                 |        |
+--------+                 +--------+
|        |                 |        |
|        |                 |        |
+--------+                 +--------+

My question is :

Is it possible to add a second SYSPLEX, sharing the same physical ICP
connections like sharing CTC connections between LPARs , like this:

  CPC1                       CPC2
+--------+                 +--------+
|        |           icp   |        |
| PLEX1a |------+  +-------| PLEX1b |
|        |      |  |       |        |
|        |      |  |       |        |
+--------+      |  |       +--------+
|        |      +--|-------|        |
|  CF1   |---------+  icp  |  CF2   |
+--------+                 +--------+
|        |                 |        |
| PLEX2a |                 | PLEX2b |
|        |                 |        |
|        |                 |        |
+--------+                 +--------+
|        |                 |        |
|  CF3   |                 |  CF4   |
+--------+                 +--------+

If the answer is positive, where can I find documentation
describing the definitions for it .
