DMX-2 & DMX-3
Hi,
I have an AIX server connected to a DMX-3 and got some space allocated to it. Now I need to connect it to a DMX-2 to add more space. Can I do that with out any issues with the same HBAs connecting to both at same time? or Can you please help me to come to a conclusion on the same?
Thanks
AJ

The starting point is your host that is connected via at least an HBA to a fabric (a storage area network/SAN). Your host can already "see" devices from a given storage.
Now just imagine you want to introduce another storage (maybe it's from a different vendor, maybe not, however it's different).
The question is: my host can see both storages ??
3 different answers.
1) shared server (strict sense)
The server can see different storages via different HBA connected to different SANs
2) shared SAN
The server can see different storages via different HBA connected to existing SAN
3) shared HBA
The server can see different storages via existing HBA and existing SAN
You can find details of supported configurations in e-lab navigator (as noted in another post of this same thread).

FAs on DMX-2 are not loaded at all and there are 4 HBAs on this server where all the four are connected with same devices. I was just concerned that using same HBAs for both connections to DMX-2 & DMX-3 is ok or not?

You can very well do that , it would be much more better given the work load is spread across different DMX's .
You can check the limit by the fan - in ratio for the HBA
Although this is my point of view , lets see what the experts have to say about the same .

However if you look at the support matrix (e-lab navigator if you prefer) you can easily find if your configuration is supported .. look at the "Mixed storage environment" line in Results.
It mainly depends on the OS and on the HBA. However it happens that we support "Shared Server" and "Shared HBA" configurations .. In case you want better details, OPEN A THREAD and be ready to award points

I must have been somewhere else in my thoughts.... Excuse me. You were right, as always.
And for now: on to the company BBQ !

Is there something called shared server/HBA matrix on e-lab navigator? I havent found that exactly. But seen multiple storage environment for non-EMC boxes
Thanks for answer and I am going to award ..... Nice talking to you Stefano, Dynamox & RRR.
Thanks
