On an IBM SVC there are IO groups. A vDisk is contained in an IO group. I'm not seeing where you can see that in the interface.
For instance, say you have four SVC nodes. They would be split into two IO groups, IO group 0 and 1. Any vDisk you create would then either exist in IO group 0 or 1, and it is sometimes necessary for server admins to know which IO group they are in, right now they cannot get that information from Profiler unless its something to customize or is tucked away?
We currently don't collect this data, but we can add it to the list for future investigation.
I'll put in the feature request.
