We just upgraded to 13.5 last weekend (from 13.0).
We use VTAM for our MSF connections between LPARS. We find that when we IPL, many times there are usually just 2 of our 5 LPARS that dont connect toe each others successfully with MSF. We end up bouncing MSF on one of those LPARS and then all recovers.
Have you seen this? Any idea what we can look at. Not easy to recreate - we dont IPL often. This has been going on for years - finally getting around to ask about it. Any other suggestions for recovery rather than bouncing MSF? A DEACTIVATE/ACTIVATE of the LAPRS in MSF dont seem to recover it.
Release : 13.5
