HP EVA-to-3PAR Online Import Migration Guide (T5494-96606)

3. Verify that the EVA can detect both ports on the 3PAR.
Ensure that the peer port WWNs appear in the discovered port list. Alternately, verify that
the EVA is shown as a connected device on both peer ports of the destination 3PAR storage
system.
Zoning a host to the destination 3PAR storage system
The migration process requires each host involved in the migration to be zoned to the destination
3PAR storage system. Paths must be created from the host to the destination 3PAR storage system.
For a host using the Online migration procedure (Linux/VMware/HPUX), zoning from a host to
the destination 3PAR storage system is performed as a pre-migration step. For hosts utilizing the
Minimally Disruptive migration procedure (Windows/AIX), this zoning is performed during the
migration process. For details on migrating from a Windows host, see “Reconfiguring the Windows
host DSM” (page 10)
Identifying source and destination storage systems
NOTE: An EVA should be selected as a source only if it is being managed by Command View
10.3.1. If a Command View 10.2 instance is included in the same management group with
Command View 10.3.1, the Add a Source Storage System screen displays EVAs for both Command
View 10.3.1 and Command View 10.3. To determine the version of a Command View instance
before selecting a source array, perform the following steps
1. In the settings point of view, determine if there are multiple instances of Command View.
2. If there are multiple instances, select each instance and check the Version/Build on the
Command View Management Properties page.
3. If the Version/Build is 10.1 or prior, note the IP address.
4. On the HP EVA to 3PAR StoreServ Online Import GUI pages check the IP addresses of the
Management Server for each array.
The source and destination storage systems that will be made available for HP EVA to 3PAR
StoreServ Online Import data migration must be identified before a migration can be performed.
This involves the following steps:
1. In Command View, select the Settings point of view.
2. In the left navigation pane, select Configuration under an HP EVA to 3PAR StoreServ Online
Import instance.
The Eligible HP EVA to 3PAR StoreServ Online Import Source/Destination Systems screen is
displayed.
