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 .

Re: Shared ICP between 2 SYSPLEXES
Do you mean CFP (ICP are Internal Coupling Peer, which have no physical connection and are limited to within a single CEC)? I believe the limitation is only that there can be only on CF accessed on each end of the CFP. Washington Systems Center published zSeries Peer Mode Links whitepaper in September of 2002. It should be available at the IBM pubs website. If you can not find it, email me and I will send you a copy.

Re: Shared ICP between 2 SYSPLEXES
I think you can - we have z9EC machines with ICB-4 links that can be shared, though we don't. In HCD define the icp as SHR and assign it to the appropriate LPAR(s). I would hope HCD wouldn't let you define an illegal configuration. I expect documentation will be found in the HCD manuals.

Re: Shared ICP between 2 SYSPLEXES
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. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Cwi Jeret Sent: Wednesday, May 16, 2007 04:25 To: IBM-MAIN@BAMA.UA.EDU 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 .

Re: Shared ICP between 2 SYSPLEXES
If you have peer mode capable links you could certainly do what you propose, but it would not be adhering to high availability connectivity design. It really depends on you comfort level, your CF structures, if you're exploiting system-managed CF structure duplexing, etc., but you might be able to achieve higher availability with just a third link containing one CF from each sysplex.
