At the CLI, yes, in an MMC, no, because the MMC is making MSRPC calls to the LWIOD on just one node at a time, which as you've indicated is very hit and miss.  So at the CLI, you could do something like this: isi_for_array -s "isi smb openfiles list" Here is my output on an empty and idle cluster: isilon3-1: ID Path isilon3-1: ------- isilon3-1: ------- isilon3-1: Total: 0 isilon3-2: ID Path isilon3-2: ------- isilon3-2: ------- isilon3-2: Total: 0 isilon3-3: ID Path isilon3-3: ------- isilon3-3: ------- isilon3-3: Total: 0   isi_for_array = runs the command on every node (-s switch) = runs the command in a serial manner, 1 node at a time, get all those responses then move to the next node.  This is slower than without the -s switch, however the results are easier to interpret.  Hope this helps: ~Chris
I've come to learn the MMC snap-in is only showing the open files from the client connections coming from the node you are connected to, not all across the cluster. This explains why files I would look for to be open would never show up. So now, within the snap in I connect to each node, and also the cluster itself, each yielding different results. My question is, is there a way to consolidate these views into one window, instead of having to have x number of Shared Folders tabs open, having to click through each one to find the open file I wish to close? Or is there an easier way to do this that I am missing? Thanks.
