Zone config for MSA2012fc (G1)
I've looked at the "How to configure soft-zones" document at http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01692989 but this does more to confuse than clarify.
It shows the output of "show port-wwn" on the MSA which clearly shows the WWNs it holds, but both of the SAN Switch configs (Blue & Red in the example)refer to the same pair of WWNs, referring to ports B0 & A0 only with no reference to B1 & A1.
So, what's the correct way to create an alias for a single MSA2012fc with dual controllers?
Any pointers gratefully appreciated!
Paul
Is this correct?

Re: Zone config for MSA2012fc (G1)
I suspect the drawing is correct: A0/B1 on one fabric, and A1/B0 on the other.

Re: Zone config for MSA2012fc (G1)
Hi Paul,
If your MSA is wired according to the example, then same port cannot show up on both fabrics, as the fabrics are not even connected to each other.
A0 and B1 should be on first fabric, A1 and B0 should be on the second.
I suggest you post us the output of cfgshow from both switches so that we can compare.
Regards,
Taurian.

Re: Zone config for MSA2012fc (G1)
Hi Paul,
If you are referring to the cfgshow output in the example on your link, then look closely. All three WWN for cfgshow on SW1 (Blue Fabric) and different from the three WWN for cfgshow on SW2 (Red Fabric). Compare initial numbers for the last two ports. They are unique on both switches.
>> but both of the SAN Switch configs (Blue & Red in the example)refer to the same pair of WWNs, referring to ports B0 & A0 only with no reference to B1 & A1.
In the example, the alias created on switches contain one WWN from each controller. Both switches contain exactly the same entries. This is due to the fact that it is the floating WWN. This is useful during failover scenarios.
You can see the failover example given at the link. It is quite self explanatory.
Regards,
Taurian.

Re: Zone config for MSA2012fc (G1)
So, A0 (20:78) & B0 (20:70) are the *only* WWNs that appear in either switch.
For my config therefore (and in a correctly cabled setup) should I only ever zone with the WWNs from A0/B0 ?f
Looking at the example failure of Controller A it does look this way, but why don't they just make it clear & state it as fact rather than forcing us to deduce it??

Re: Zone config for MSA2012fc (G1)
This is very much contrary to my previous experience configuring switches for EVA's...
Anyhow, I've now configured the zones & things are working. Tomorrow I'll initiate some failovers and see if that trend continues!
