• 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. Table 70 ExposePath Use Cases Use Cases LUNames Create a new Mandatory view Add InitiatorIDs to View (valid only for host-see SPC, and matched-set SPC only if initiator port is already zoned with the target port) NULL Add LUs to view Mandatory InitiatorPortIDs TargetPortIDs Mandatory if creating a matched-set or host-see SPC, NULL if creating a port-present SPC Mandatory if creating a matched-set or port-present SPC; NULL if creating a host-sees SPC Mandatory NULL DeviceNumbers DeviceAccesses ProtocolControllers (On input) Optional Mandatory NULL NULL NULL Contains a single SPC ref NULL NULL Optional NULL Contains a single SPC ref; if this is a TPD_iSCSINode, this operation is equivalent to creating a port-present SPC for that iSCSI port Parameters "Override" and "NoVCN" are optional. All other combinations of the parameters are rejected. 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. 82 CIM API SMI-S Support
