HP 3PAR CIM API Programming Reference (OS 3.1.2 MU2) (QL226-97015, June 2013)

• Override: Override existing lower priority VLUNs, if necessary. Can be used only when
exporting to a specific host. This parameter is a vendor-specific extension. The default value
is false.
• NoVCN: Do not issue a VLUN (Virtual Logical Unit Number) Change Notification (VCN) after
export. 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. 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 expose path operation. This parameter is a vendor-specific
extension.

HidePaths (Removing VLUNs)
HidePaths() is the inverse of ExposePaths. It hides a list of storage volumes from a list of
initiators through a list of target ports, through one or more SCSIProtocolControllers (SPCs).
This operation is similar to removevlun. Host-sees VLUNs can also be removed by
HideLUsFromStorageHardwareIDCollection. One difference between this method and
the CLI removevlun command is that for this method, the exact host WWN/iscsiName is specified
(InitiatorPortIDs), whereas for the removevlun command, the name of the host is specified,
not the WWN/iscsiName itself.
