Local fix
Problem summary
TPC-R does not show hyperswap in a degraded state, it only shows enabled or disabled. The session pairs should show errors on the pairs and propogate up to the session status. This was cuased because TPC-R could not see that the config exists through IOS.
Problem conclusion
The fix is a collaboration between TPC-R and IOS. TPC-R set up a new HSRP structure and added new messages to handle this use case. IOS component of zOS updated code in APAR OA38871 Now TPC-R will now show degraded state in a HyperSwap session if only part of the session is HyperSwap capable.
Temporary fix
