Disabling multipathing and making devices invisible to VxVM Administering Dynamic Multipathing

Disabling multipathing and making devices invisible to VxVM

Use this procedure to prevent a device from being multipathed by theVxVM DMP driver (vxdmp), or to exclude a device from the view of VxVM.
Warning:
A reboot of the system may be required.
To disable multipathing and make devices invisible to VxVM
  1. Run the vxdiskadm command, and select Prevent multipathing/Suppress devices from VxVM's view from the main menu. You are prompted to confirm whether you want to continue.
  2. Select the operation you want to perform from the following options:
    Option 1
    Excludes 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.
    Option 2
    Excludes specified paths from the view of VxVM.
    Option 3
    Excludes disks from the view of VxVM that match a specified Vendor ID and Product ID.
    Option 4
    Defines 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.
    Option 5
    Disables multipathing for all disks on a specified controller.
    Option 6
    Disables multipathing for specified paths. The disks that correspond to a specified path are claimed in the OTHER_DISKS category and are not multipathed.
    Option 7
    Disables 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.
    Option 8
    Lists the devices that are currently suppressed or not multipathed.
