An error occurred while the system tried to claim a Multipath I/O (MPIO) path. The location of the failing path is described by the SCSI address (4, 0, 1, 0) (Port, Bus, Target, Lun). To resolve this issue, either reboot the system, or show hidden devices in Device Manager and try uninstalling the specific disk device indicated above, and then rescan for hardware changes.
