Hi Shane,
We are using NetApp MPIO and everything is correct, looks like I wasn't clear enough on my question.
Actually when I create a LUN from SDW and use automatic mapping than SDW creates 4 igroups on filer for 2 node windows cluster (2 FC port/host), however going this way soon we will hit max igroup limit of filer which we don't want.
Now if we manually create an igroup on filer which has all 4 WWN then we can't create luns from SDW as on mapping screen SDW doesn't lists igroup which we have created manually because it has WWN of other windows cluster node as well, however if we create one igroup per host which has both the ports of host then it lists correctly in igroup window.
So my question is why SDW can't list an igroup which has WWN of other node of cluster?
Hope my lengthy question makes sense.
