We originally had an MSA30 directly attached via a HP6400 controller to a HP DL380. We upgraded the storage and are now using an MSA1500 instead of the 6400. All of the arrays and partitions were detected by the new controller and the volumes came up in Windows with the same drive letters etc. One issue however, for every partition connected to the MSA1500 we have a duplicate "unknown", "uninitialised" disk in disk management. Every time you open disk management it prompts you to install and initialise the duplicate disks but when you do you get an error "The operation did not complete. Check the system event log for further details.", guess what, there's nothing in the event log!
Every array subsequently created on the controller gives up 2 disks, one that will initialise and one that wont. Is there a way to remove these rogue disks and stop duplicate disks from being detected? As ever, all help and suggestions greatly appreciated.
