Disabling DMP multi-pathing for vSCSI devices in the Virtual IO Client, after installation

After VxVM is installed, use the vxddladm command to switch vSCSI devices between MPIO control and DMP control.

To return control to MPIO, disable vSCSI support with DMP. After DMP support has been disabled, MPIO takes control of the devices. MPIO implements multi-pathing features such as failover and load balancing; DMP acts in pass-through mode.

To disable vSCSI support within DMP and enable MPIO

  1. Disable vSCSI support.
    # vxddladm disablevscsi
  2. You are prompted to reboot the system, if required.
