Issue/Introduction
Separate TPX instances are setup for PROD, DEV and TEST environments.
Normally, PROD TPX is used to access DEV and TEST TSO sessions.
However, after upgrading TEST LPAR from z/OS 2.4 to 2.5 the behavior changed.
An attempt to access TSO session on the TEST LPAR from PROD TPX, the following error was observed and access to TSO on TEST LPAR failed. PROD and DEV are still running z/OS 2.4.

While using TPX from TEST LPAR to access TSO sessions, PROD, DEV and TEST were accessible.
On RE-IPLing TEST LPAR back to z/OS 2.4 access to TSO sessions on all 3 LPARs worked fine.
What is causing this anomaly ?
Environment
Release : 5.4
Component :TPX for Z/OS
Resolution
This appears to be VTAM cross domain setup condition from Sense code 087D as shown below:
Ref : Sense code 087D
Session services path error: A session-services request cannot be rerouted
along a path of SSCP-SSCP sessions. This capability is required, for example,
to set up a cross-network LU-LU session.
The problem was resolved by activating the CDRMS node for both the LPARs. This was missing when the TEST LPAR was IPL-ed with z/OS 2.5.
