CIM API Programming Reference
 NoVCN: Do not issue a VLUN (Virtual Logical Unit Number) Change Notification (VCN) after
removal. For direct connect or loop configuration, a VCN consists of a fibre channel Loop
Initialization Primitive (LIP). For fabric configuration a VCN consists of Registered State
Change Notification (RSCN) being sent to the fabric controller. This parameter is a vendor-
specific extension for 3PAR. The default value is false.
 ResultDescriptions[]: An array of descriptive text of the result of the operation, with each
entry containing the result of each hide path operation. This parameter is a vendor-specific
extension for 3PAR.
Parameters
DeviceNumbers and NoVCN are optional. All other combinations of the
parameters are rejected.
The use cases are:
 Remove volumes from a view: the volume has been exported to an SPC, it’ll be removed
from the SPC (e.g. it won’t be accessible from host HBA anymore).
 Hide full paths from a view: similar to Remove LUs from a view, but
InitiatorPortIDs and TargetPortIDs parameters are included.
