Mapping LUNs to FA's

I have a question about LUN mapping. Is there a limit to how many paths you can have to each LUN through FA's? Is there a limit to the number of FA's that a LUN can be mapped to? We want to map a Meta to 4 FA's giving 4 paths to that LUN, can this be done?

thanks for any help.

Yes you can map your lun to multiple FAs .. It's the "right way" on DMX :D

I've personally mapped devices on 8 different ports .. I'm not aware of limits while mapping a volume on multiple FAs. The only limit I can see is the number of devices you can map on a single FA. But it's a whole different thread ;-)

You can map to every FA port in the frame. Your limitation will probably be your multipathing solution. I cannot think of any environment that would not let you run on 4 paths. PowerPath will certainly work.

We all said slightly different things .. He can choose the "best" answer (and mark it "correct") and however award all other answers as "usefull" :D ..

I don't want points .. I simply expect the user to mark better answers so that others may easily find the correct answer to this question .. :-)
