Not sure what splitter we're talking about here but have you tried to remove any stale resource pool you have under the registered array in the storage tab ?
If this is not applicable (storage doesn't show up under storage tab, etc.), I would open a SR so that we'll be able to take a closer look at the reason we're presenting this warning.
Hope that helps,
It is a VNX and I have tried to remove the resource pool under the registered array in the storage tab, however without any luck.
The first time I actually did it, RPA1 rebooted, then on the next two occasions the cluster was loosing access for a moment and then was coming back.
Would you recon that if I detach and re-attach the RPs would help?
Thanks for your time.
I would recommend to open a SR for us to take a closer look.
