Disabling multipathing and making devices invisible to VxVM

Use this procedure to prevent a device from being multipathed by the VxVM DMP driver (vxdmp), or to exclude a device from the view of VxVM.

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

    Suppresses all paths through the specified controller from the view of VxVM.

    Option 2

    Suppresses specified paths from the view of VxVM.

    Option 3

    Suppresses disks from the view of VxVM that match a specified Vendor ID and Product ID combination.

    The root disk cannot be suppressed.

    The operation fails if the VID:PID of an external disk is the same VID:PID as the root disk and the root disk is under DMP rootability control.

    Option 4

    Suppresses all but one path to a disk. Only one path is made visible to VxVM.

    Option 5

    Prevents multipathing for all disks on a specified controller by VxVM.

    Option 6

    Prevents multipathing of a disk by VxVM. The disks that correspond to a specified path are claimed in the OTHER_DISKS category and are not multipathed.

    Option 7

    Prevents multipathing for the disks that match a specified Vendor ID and Product ID combination. 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.
