Thank you, Alan. Using ifconfig, I see that the interface is listed as
DOWN:
GBE200 inet addr: 10.254.145.64 mask: 255.255.255.0
DOWN MTU: 8992
vdev: 2912 rdev: 2912 type: QDIO ETHERNET portname: DEV2900
ipv4 router type: NONROUTER ipv6: DISABLED
cpu: 0 forwarding: ENABLED
RX bytes: 1080326 TX bytes: 1719553
When I try to bring it up with "ifconfig gbe200 up", it says:
DTCIFC2654E TCPIP is unable to link to your 191 minidisk which is
DTCIFC2654E currently accessed as file mode A
and the interface says down. I've tried it as TCPMAINT and as MAINT
(linking to TCPMAINT's 592 disk).

1. Ask yourself and your colleagues "what changed?"
2. Look at the TCPIP console and see if you have any errors.
3. Issue "ifconfig -a" and see if everything you expect to be UP is up.
4. QUERY VSWITCH to see if they are in the state you expect.
5. At some point in the past you drew a picture of the network into which
you placed VM TCP/IP. Confirm with your network architects that the
picture is still correct (subnet masks & routers).
