VIO Server MPIO Disk Configuration Procedures

This document describes the procedures for configuring MPIO disks on a VIO Server to be shared out to client LPAR's. A single procedure has been developed for use in standalone, High Availability, and Disaster Recovery environments. This procedure provides the mechanism to configure MPIO disks on all VIO Servers regardless of whether a single or dual VIO servers are implemented.

Two distinct mechanisms are used for defining the MPIO virtual disk names on the VIO server, these standards can be viewed at the following URL:

viompiostand.shtml

The remainder of this configuration standard discusses the procedure for naming virtual disks on the VIO server using the "mkvdev" command.

Procedure Outline:

Create a "vhost" adapter for boot disk(s) for each system
Create a "vhost" adapter for paging disk(s) for each system
Create a "vhost" adapter for application disk(s) for each system
Determine hdisk(s) on VIO server to use for client boot disk(s)
Determine hdisk(s) on VIO server to use for client paging disk(s)
Determine hdisk(s) on VIO server to use for client application disk(s)
Determine resource group and volume group names on client LPAR
Create script to perform hdisk, vhost, virtual disk name assignements

An example script that performs the hdisk, vhost adapter, and virtual disk name assignments follows:
