Events 1 to 4 in the preceding list are generated on successfully completing the following corresponding user or administrator initiated operations (AddCdev, RemCdev, AddVD, and RemVD respectively):

*

NytroXDAddCacheDevice for the AddCdev operation.

*

NytroXDRemoveCacheDevice for the RemCdev operation.

*

NytroXDAddVirtualDrive for AddVD operation.

Event 5, NytroXDVirtualDriveOffline, is generated after the Nytro XD Kernel completes the cache invalidation as a part of detecting that a VD has gone offline. Event 6, NytroXDVirtualDriveOnline, is generated by the Nytro XD Kernel when it learns that the OS has detected that a VD has come online. The corresponding online VD operation must be initiated by the user or administrator.
