Part V Migrating Data
The HP 3PAR Peer Motion feature controls the migration of data from a source system to a destination system.
A user can copy the virtual volumes and system configuration information to a new system without changing
host configurations or interrupting access to the volumes. Any available free port can be used for Peer
Motion.
There are three types of migration: online migration, minimally disruptive migration, and offline migration:
•
Online – Used to migrate virtual volumes that are exported to a host. This migration type requires
unzoning the host system from the source system.
•
Minimally Disruptive – Used to migrate virtual volumes that are exported to a host. This migration type
requires shutting down the host system for a short period of time. Additionally, the destination system
must be running OS version 3.1.2 or higher.
•
Offline – Used to migrate virtual volumes that are not exported to a host. Exported volumes that you
want to migrate must first be unexported to use offline migration. No unzoning or system shutdown is
required.
After the data migration is complete, the source system can be disconnected from the hosts and repurposed.
