We have reported a similar problem where a Linux server -will- ping a peer on the same Virtual Switch until such time as the Linux server shuts down and reboots. After the reboot a Linux server can -no longer- ping another Linux server on the same Virtual Switch. Odd. But very repeatable. The circumvention is to shutdown Linux, log the virtual machine off, log back onto VM, then reboot Linux.
In other words, a virtual machine reIPL leaves to servers unable to speak to each other, although they can speak to the outside world. I am suspicious of VM63895. IBM suspects a difference in the VLAN tagging of the frames. I wonder why a reIPL vs. a logoff/logon should matter, with regard to VLAN tagging. But I readily admit that this is an area of TCP/IP where I have limited skills. (PMR 57324 may be of interest to any IBMers.)

Recently we added two more guests with SP3 installed, for some reason the SP3 guests can't "see" the older servers and also there is no communication between the two SP3 servers. Both SP3 servers are able to "see" the whole internal network plus they have connection to the Internet. Any ideas??? Thanks in advance... Regards, José L.
