After a lot of effort I could demonstrate to IBM the problem we had using a program called linkloop , LAYER 2 ping program. IBM did find a bug in OSA-Express3 1000T (z10) driver. OSA is unable to handle any inbound LAYER 2 traffic with VLANS enabled (in bound Ethernet frame with group bit turned on were buffered) if there is no TCP/IP stack defined. They provided us a Temp MCL fix for our issue. This OSA fix will included in the next micro code driver level.
We are running driver 79 with temp MCL loaded for the OSA fix.

We are running OSA CODE LEVEL = 0732 and would like to double check with your OSA code level. We were pointed to kernel 2.6.25 when we opened an ETR with IBM on this issue. Did you also upgrade to a new kernel for the OSA3. We are running kernel 2.6.18-164.el5. We checked all of VSWITCH, NIC def and Linux interface definitions and everything appears to be correct. We made sure we defined the network as "layer 2" confirmed from sysfs.

We had some OSA issues last week with a z9->z10 upgrade and the reload fixed them. Marcy "This message may contain confidential and/or privileged information.

You could get this error if the guest tried to configure layer 3 on an layer 2 VSWITCH or the guest configured the vNIC prior to the COUPLE to the VSWITCH. All that would be required is to log the user off/on or detach the NIC and re-define it. If the ONLY thing you changed was z9->z10 and you have the support for OSA-Express3 (if that's what you're using) applied, then call it in. Just double-check that Linux is configured to do layer 2. I have seen systems do odd things after a h/w change because something was dependent on the system identifier or CPU serial number.
