Select option 1 to exclude all paths through the specified controller from the view of VxVM. These paths remain in the disabled state until the next reboot, or until the paths are re-included.
Select option 2 to exclude specified paths from the view of VxVM.
Select option 3 to exclude disks from the view of VxVM that match a specified Vendor ID and Product ID.
Select option 4 to define a pathgroup for disks that are not multipathed by VxVM. (A pathgroup explicitly defines alternate paths to the same disk.) Only one path is made visible to VxVM.
Select option 5 to disable multipathing for all disks on a specified controller.
Select option 6 to disable multipathing for specified paths. The disks that correspond to a specified path are claimed in the OTHER_DISKS category and are not multipathed.
Select option 7 to disable multipathing for disks that match a specified Vendor ID and Product ID. The disks that correspond to a specified Vendor ID and Product ID combination are claimed in the OTHER_DISKS category and are not multipathed.
Select option 8 to list the devices that are currently suppressed or not multipathed.
