Migrating Data; Create Peer Volumes - HP 3PAR StoreServ 7200 2-node Manual

Migrating Data

To use the Migrate Data wizard, the following conditions are required:
Super user role
Peer Motion license
Any Peer Motion configuration that includes a source and destination system whose status is
Normal and that has no other admitted or importing volumes.
Perform the following tasks before using the wizard:
Configure the data migration process by using the Create PM Configuration wizard.
Copy the desired settings from the source system to the destination system using the Copy
Storage Settings and Configurations wizard.
Determine the best time to do the data migration. (A period of low usage is best, as migration
incurs I/O latency.)
The Migrate Data wizard guides you in migrating volumes from the source system to the destination
system. The types of migration are as follows:
Online – Used to migrate virtual volumes that are exported to a host. This migration type
requires unzoning the host system from the source system. (The default migration type is Online.)
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. The destination
system must be running OS version 3.1.2 or later.
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.
WARNING!
mpclaim CLI command or attempt to display the MPIO information through the Disk Management
GUI during the Peer Motion migration admitvv stage. Doing so will result in the host becoming
unresponsive.
NOTE: A warning message appears if either of the following licenses is missing:
Thin provisioning (needed to create a thin volume)
Domain (needed to add the volumes to a domain that is not the <none> domain)
When the migration host exists, a warning appears to clean it up.
To migrate data:
1. Select Peer Motion in the Manger Pane.
2. In the Common Actions panel, click Migrate Data.
