Re: New switch question.

[Rob Berendt <robertowenberendt@xxxxxxxxx>]

Doing a major upgrade this week...
Can you see any four digit numbers on the cards?  Like 5337 or some such
thing?
Is it possible that the two cables are RJ45 and they are going to the
switch for ethernet?
And maybe the 'thin cable' going directly to the SAN is a fiber cable for a
fiber channel connection?
Are you using VIOS for virtualization?
If you do
WRKLIND do you see your ethernet line?  Do 5=Display on that and record the
resource name.
WRKHDWRSC TYPE(*CMN) and find that resource.  7=Display resource detail
should tell you the physical card and port (unless you're virtualizing it
or using link aggregation or...)

Now, as far as that thin cable goes...WRKHDWRSC TYPE(*STG) and a little
drilling down might show you the hardware used there with basically the
same caveats noted above.
