AIX had connectivity once the physical switch was back online. our zVM 4.4 vswitch did not - thus the question of how to get it back.
AIX 5.3 has VIO servers which allow for failover between network connections - but, no - it would not tolerate an adapter being unplugged. the 'SET VSWITCH CONNECT' was the command i was looking for. prg Phillip Gramly Systems Programmer Communications Data Group Champaign, IL > I don't know what "like AIX" means, so I can't answer your question. > > If you actually have an OSA problem that requires the offline/online reset > dance, as soon as the OSA goes away the VSWITCH will switch to a backup. > Of course, if you keep pulling all the OSAs out from under the VSWITCH, > there's not much it can do.
