            [UNINSTALL]

    Makes the currently selected LUN accessible from the specified host(s).

    ALL         Specifies that the LUN should be made accessible from all
                hosts that are discoverable by the VDS Hardware provider 
                supporting the subsystem. This generally always includes 
                the local host server, and may include other servers.

    NONE        Specifies that the LUN should not be accessible to any host
                server.

    ADD         Specifies that the given host servers must be added to the
                existing list of host servers that are able to access this
                LUN.

                If this parameter is not specified, the list of specified hosts
                replaces the existing list of hosts that this LUN is accessible
                from.

    WWN=[;[;...]]

                Used with PCI RAID, Fibre Channel or SAS subsystems.
                
                Specifies a list of World Wide Names of host ports that the
                LUN should be made accessible to. Each WWN is separated by
                a semicolon.
                
                For example if you specify the WWN of the Fibre Channel HBA 
                port on Server1, the LUN becomes visible as an operating 
                system disk at Server1.

    INITIATOR=[;[;...]]

                Used with iSCSI subsystems.

                Specifies a list of iSCSI host initiator names. Each iSCSI host
                initiator name is separated by a semicolon.

                Although a LUN must be selected to run this command, the
                command may operate on the target containing the LUN, rather
                than a specific LUN.

                The behavior of this command differs depending on the
                iSCSI implementation. For example,

                1) Some iSCSI implementations may put all LUNs in one target.

                2) Some iSCSI implementations may create one target per LUN.

                3) Some iSCSI implementations may allow multiple targets, and
                   allow the user to associate LUNs with specific targets.
                   This implementation is used by the Microsoft iSCSI Software
                   Target.

                At a minimum, this command specifies that the target
                associated with the LUN will allow the given initiator access
                to the target.

                For some implementations, allowing initiator access to a target
                means that once the initiator logs in to the target, the
                initiator will have access to all LUNs contained in the
                target. This implementation is used by the Microsoft iSCSI
                Software Target. For the Microsoft iSCSI Software Target, 
                access is restricted by placing LUNs in multiple targets, 
                and then allowing access on a per-target basis.

                For other implementations, the initiator may have access only
                to the LUN that is selected when the command is run.


    UNINSTALL   If specified, uninstalls the disk associated with the LUN, 
                on the local system, before the LUN is masked. Before 
                uninstallng the disk, for each volume with extents on 
                the disk, the file system is dismounted, the volume is 
                offined and the volume is uninstalled. Also removes obsolete 
                drive letters and mounted folders associated with volumes
                on the disk.


    A LUN must be selected for this operation to succeed.

Examples:



    UNMASK LUN NONE
    UNMASK LUN WWN=10000000C9241FBD
    UNMASK LUN ADD WWN=100000009E3F0076;100000009E3F8A73
    UNMASK LUN INITIATOR=iqn.2429-08.com.myinitiators.initiator-3
