Have you checked the hardware connections to make sure the end to end process is working? Do you have a physical cable issue? Do you have a physical channel connection issue? How is it connected? Ficon, escon, Cicso routers? Any hardware from point a to point b needs to be looked at.
I will usually run LOGREC with the following control cards. Verbose but I can get an idea of what kind of flags are set. ZERO=N PRINT=AL TYPE=CDEHIMOS DATE=(07288,07288) TIME=(0400,0500) ACC=N ENDPARM The IOS050I is stating you have a hardware error. The only way to fix it is to correct the issue. I would look at the logrec and see what flags are set ... Do you have any of the following details in your logrec?
