Description

Setting up DMP for vSCSI devices in the Virtual I/O Client

See Using Storage Foundation in the VIO client with virtual SCSI devices

In this release of Storage Foundation, Veritas Dynamic Multi-Pathing (DMP) is enabled on VIO clients by default. After you install or upgrade Storage Foundation in the Virtual IO client, any vSCSI devices are under DMP control. 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.
