Logical Domains 1.3 Administration Guide

Logical Domains P2V Migration Tool Overview

The Logical Domains P2V Migration Tool automatically converts an existing physical system to a virtual system that runs in a logical domain on a chip multithreading (CMT) system. The source system can be any of the following:

The conversion from a physical system to a virtual system is performed in the following phases:

For information about the P2V migration tool, see the ldmp2v(1M) man page.

The following sections describe how the conversion from a physical system to a virtual system is performed in phases.

Collection Phase

This phase runs on the system to be converted. To create a consistent file system image, ensure that the system is as quiet as possible and that all applications are stopped. ldmp2v creates a backup of all mounted UFS file systems, so ensure that any file systems to be migrated to the logical domain are mounted. You can exclude mounted file systems by using the -x.

No changes are required on the source system. The only thing required is the ldmp2v script that was installed on the control domain. Depending on the selected archiving method you intend to use, ensure that the ufsdump or flarcreate utility is present on the source system.

Preparation Phase

The preparation phase uses the data collected during the collection phase to create a logical domain that is comparable to the source system.

You can use the ldmp2v prepare command in one of the following ways:

Conversion Phase

In the conversion phase, the logical domain uses the Solaris upgrade process to upgrade to the Solaris 10 OS. The upgrade operation removes all existing packages and installs the Solaris 10 sun4v packages, which automatically performs a sun4u-to-sun4v conversion. The convert phase can use a Solaris DVD iso image or a network install image. You can also use Custom JumpStart to perform a fully automated hands-off upgrade operation.
