Re: What does is casing er_unroutable

er_unroutable is a common message and most related - no matter if the environments is Open or FICON - to lost Frames.


This may can be caused for several reason, i.e. defective SFP of cable, but also some wrong settings on Host / Storage site.


FICON is a bit sensitive as an Open environments, at this point if the error was not reported in the past, I would procede to plan a maintenance Window and replace SFP and cable at all, bevore made some config change.
