Configuring Dynamic Multi-Pathing (DMP) on Virtual I/O server

You can install DMP in the virtual I/O server (VIOS). This enables the VIO server to export dmpnodes to the VIO clients. The VIO clients access the dmpnodes in the same way as any other vSCSI devices. DMP handles the I/O to the disks backed by the dmpnodes.

For support information concerning running Dynamic Multi-Pathing (DMP) in Virtual I/O server (VIOS), see the Veritas InfoScale Release Notes.

Dynamic Multi-Pathing (DMP) can operate in the Virtual I/O server. Install DMP on the Virtual I/O server.

To install DMP on the Virtual I/O server

  1. Log into the VIO server partition.
  2. Use the oem_setup_env command to access the non-restricted root shell.
  3. Install Dynamic Multi-Pathing on the Virtual I/O server.

    See the Storage Foundation Configuration and Upgrade Guide.

  4. Installing DMP on the VIO server enables the dmp_native_support tunable. Do not set the dmp_native_support tunable to off.
    dmpvios1$ vxdmpadm gettune dmp_native_support
Tunable               Current Value  Default Value
------------------  --------------- -------------------
dmp_native_support       on              off

Migration options for configuring multi-pathing on a Virtual I/O server:

  • Migrate from other multi-pathing solutions to DMP on a Virtual I/O server

  • Migrate from MPIO to DMP on a Virtual I/O server for a dual-VIOS configuration

  • Migrate from PowerPath to DMP on Virtual I/O server for a dual-VIOS configuration
