There are two ways to allow HP command View EVA that’s installed in a virtual machine to manage the array: Virtualized SCSI mode and VMDirectPath mode.
Virtualized SCSI mode – The Command View EVA instance can only view the active path to LUN
0 on a single controller. This mode is enabled by default when you install Command View EVA
9.2 or later.
If all HP hardware and software are on the VMDirect I/O supported list. Then you can use VMDirectPath mode.
VMDirectPath mode – The Command View EVA instance bypasses the virtualization layer and
can directly manage the EVA storage. This mode is supported on Command View EVA 9.3 or
later.
