Hi Steve, thanks for your answer. The two sites are 30km apart and we have a DWDM network between the Ficons. The amount of data we sent has probably increased, but we started getting the IOS050I when no change was made. We also checked the buffercredits, doubled them for testing, but did not work. I forgot to say that we have 8 ficon director, 4 at each site, and we get the IOS when data travels through 3 pairs.
We will change the involved SFPs and give it a new try. Thank you again for your answer. Regards, Christian. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
