Jumping in at the middle, so I apologize. I probably missed something. Is this something that just stopped working or isn't working with a CPU upgrade? In a recent upgrade I did we had some OSA OSE ports that wouldn't activate and that is due to the 1G speed but after talking to the LAN / WAN network team I found the switch was hard coded at 100M. No one knows why... lost history from z9, z196, z12, z13 upgrades.. Maybe printers or something had to have that long ago. (OSA OSE ports support SNA and TCPIP for those not in the know).
Anyway, changing it to auto negotiate on the switch fixed it. I did have to disable / re-enable the port on the HMC for it to connect, so it wasn't just a switch change to fix it. Luckily we ran into the problem on our DR box upgrade first where it wasn't a real problem and we knew what to do for 3 CPCs in production (2 OSE ports on each) and actually swapped them all to 1G prior to the z15 upgrades. Now onto the next challenge in that z/OS 2.6 will not support the SNA connections currently in use on the OSEs. Turns out none are really used any more except on 2 LPARs to connect to AIX machines and those connections need to be migrated to Enterprise Extender. We have a little time though. :) Best Regards, Mark -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS ITIL v3 Foundation Certified mailto:m...@mzelden.com Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://search390.techtarget.com/ateExperts/ On Mon, 15 Aug 2022 23:14:49 -0700, Tom Brennan <t...@tombrennansoftware.com> wrote: >Is it a 10G (1 port) or 1G (2 port) OSA card? 10G cards won't negotiate >speed, from what I've seen. > >On 8/15/2022 10:21 PM, Jake Anderson wrote: >> Hi >> >> The OSA port is connected with working cable LC-LC MM fibre to the 1g >> switch.
