Recently we are faced with a peculiar issue. We have a lpar with a virtual adapter id 500 and xxx pvid, It was working fine until recently when it stopped communicating. Suddenly system was unreachable from outside. We tried many things finally changing the adapter id from 500 to 510 and re-configuring the adapter resolved the the issue. Now what's bothering me is that adapter id are just for naming sake, just changing the adapter how it resolved the issue. what could be the reason?
Would appreciate any insight on this.
