Can you provide the detailed results from errpt? I'd like to see if there
are any sense error codes for the transient error.

Subject: Error log entries following SP Switch Efence

We had a switch adapter failure a couple of days ago. (This is the old SP
Switch: not the newer ones, but not the very old HiP Switch.) Unfortunately,
the node - an S7A - is still on AIX 4.3.3 and PSSP 3.2, so we didn't have a
lot of luck getting assistance from IBM.

I was able to re-start the Worm daemon and Eunfence the node, so the
consensus was that it was a one-off glitch, and just to ignore it for now.

I've been getting the server ready to re-start the application - it's in an
HACMP cluster, so the application is on the standby server at the moment -
and took the opportunity to re-boot it - partly to see what happened to the
switch.

Well, the switch adapter came up as normal. But I noticed an odd error in
the error log from the Efence I issued before rebooting.

EBF464AF 0114102804 P H css Switch adapter link outage
E94651FA 0114102804 T H css Switch adapter transient error
DC85B51D 0114102804 I O Worm Node fence request received
DC85B51D 0114102804 I O Worm Node fence request received

It's the transient error that interests me in particular.

I can't remember if this is normal for the SP Switch. I tried Efence again
for this node and it produces the same results. Unfortunately I don't have
a test system which I can fence, for comparison. None of the other systems
have been Efenced recently, so they don't have any useful entries in their
error logs.

Can anyone tell me if this is a normal sequence of error log entries for a
simple "Efence node" operation?
