We are trying to get two TCPIP stacks in separate LPARs to
talk to each other over a CTC link.
We have our CTCs defined in our IOCP as shown at the end of this posting
(We took our clues from "VM New User How To Defining ESCON CTCs Between
LPARs" by Shimon Lebowitz.)
Before trying to get the LPARs to talk, we checked things out on a
second level machine. Things worked OK.
------------- Connecting second level tcpip to first level tcpip ----
------------- over CTCs ----
<<<<<<<< TCPIP profile in first level tcpip
; DEVICE AND LINK from TCPIP1
DEVICE CTCVDEVA CTC 726
LINK CTCVLNKA CTC 0 CTCVDEVA
HOME
xxx.yyy.zz.10 CTCVLNKA
GATEWAY
xxx.yyy.zz.9 = CTCVLNKA 1500 HOST
START CTCVDEVA
<<<<<<<<<<< TCP/IP profile in second level tcpip
; DEVICE AND LINK from TCPIP2
DEVICE CTCVDEVA CTC 726
LINK CTCVLNKA CTC 1 CTCVDEVA
HOME
xxx.yyy.zz.9 CTCVLNKA
GATEWAY
xxx.yyy.zz.10 = CTCVLNKA 1500 HOST
START CTCVDEVA
<<<<<<<<<<< Commands issued to connect the two TCP/IP stacks
First level TCPIP (TCPIP1)
Define ctc 726
Define CTC 727
Second level VM (TESTVM)
Define CTC 726
Define CTC 727
Couple 726 TCPIP1 726
Couple 727 TCPIP1 727
Second Level TCPIP stack (TCPIP2)
ATTACH 726 TCPIP2
ATTACH 727 TCPIP2
Start TCPIP's and things were communicating
Then we tried the LPARS. The Second Level VM IPLed fine in the LPAR
and TCPIP2 start fine.
We changed the SYSTEM DTCPARMS files in both TCPIP1 and TCPIP2
to Attach the LPAR CTCs.
We added to TCPIP1 and TCPIP2 DTCPARMS with the Tags
:ATTACH.0500 as 0726, 0440 as 727
After restarting the IP's the CTCs are defined but give
IO errors.
We may be (or actually are) totally
confused about which device addresses from the IOCP
actually can be used to connect LPAR1 (ESA11) to LPAR3 (IFL).
We thought we understood the Lebowitz notes (good examples of
defining the IOCP) but there were no
examples of how to use the IOCP CTCs after they are
defined in the IOCP so we did some guessing.
Any pointers on where to get a handle on how to do this would
be appreciated.
