Disabling multi-pathing and making devices invisible to VxVM

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

To disable multi-pathing 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.

    Option 4

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

    Option 5

    Prevents multi-pathing for all disks on a specified controller by VxVM.

    Option 6

    Prevents multi-pathing of a disk by VxVM. The disks that correspond to a specified path are claimed in the OTHER_DISKS category and are not multi-pathed.

    Option 7

    Prevents multi-pathing 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 multi-pathed.

    Option 8

    Lists the devices that are currently suppressed or not multi-pathed.
