Setting up DMP for vSCSI devices in the logical partition (LPAR)

DMP is enabled on LPARs by default. After you install or upgrade Storage Foundation in the LPAR, any vSCSI devices are under DMP control and MPIO is disabled.

If you have already installed or upgraded Storage Foundation in the Virtual I/O client, use the following procedure to enable DMP support for vSCSI devices. This procedure is only required if you have previously disabled DMP support for vSCSI devices.

To enable vSCSI support within DMP and disable MPIO

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

DMP takes control of the devices, for any array that has DMP support to use the array for vSCSI devices. You can add or remove DMP support for vSCSI for arrays.
