This weekend the LAN team upgraded the CISCO router connected to the OSA
card. The VSWITCH controller console shows the message:
DTCOSD309W Received adapter-initiated Stop Lan
after which it tries to fail over from the primary OSA to the backup OSA.
Eventually I see:
DTCOSD306I Received adapter-initiated Start Lan
and the backup OSA addresses get started fine and assign all the IP
addresses.
There are several more iterations of Stop Lan and Start Lan, but it is
always on the backup OSA addresses, never on the primary OSA addresses.
So the question is: why didn't it ever try to restart on the primary OSA
when the backup OSA received the Stop Lan? If both OSA cards were the
same it might not matter that much, but the primary is a Gig-OSA and the
backup is a Fast-OSA.

Oh, and just to make it more fun, lastly there is a Stop Lan, the various
normal messages about stopping, attempting to restart, and:

DTCOSD100E Insufficient Fixed Page Storage Pool storage
after which it tries to shutdown and then goes into repeated:

abends. Needless to say there were a lot of dump files in spool space.
So, IBM will get a call on the abends. I could add more virtual storage
to the controllers, but that will presumably only add cushion for more
stops & restarts before it runs out of storage again.
