Storage Migration Wizard Tasks - IBM Storwize V5010 Manual

Important: If you are migrating volumes from another IBM Storwize product, be aware that
the target Storwize V5000 Gen2 system needs to be configured at the replication layer for
the source to discover the target system as a host. The default layer setting for the
Storwize V5000 Gen2 is storage.
Ensure that the Storwize V5000 Gen2 system is configured as a replication layer system.
Enter the following command:
chsystem -layer replication
If you do not enter this command, you cannot add the target system as a host on the
source storage system or see source volumes on the target system.
To change the source Storwize system to the storage layer, enter the following command:
chsystem -layer storage
For more information about layers and how to change them, see Chapter 10, "Copy
services" on page 485.

7.3.4 Storage migration wizard tasks

The storage migration wizard is designed for an easy migration of data from other storage
systems to the internal capacity of the Storwize V5000 Gen2.
This section describes the following storage migration wizard tasks:
Avoiding data loss
Verifying prerequisites for Fibre Channel connections
Verifying prerequisites for SAS connections
Verifying prerequisites for iSCSI connections
Identifying restrictions and prerequisites for the wizard
Preparing the environment for migration
Mapping storage
Migrating MDisks
Configuring hosts
Mapping volumes to hosts
Selecting a storage pool
Finishing the storage migration wizard
Finalizing migrated volumes
Avoiding data loss
It is prudent to avoid any potential data loss by creating a backup of all of the data that is
stored on the hosts, the existing storage systems and the Storwize V5000 Gen2 before you
use the storage migration wizard.
Verifying prerequisites for Fibre Channel connections
Cable this system into the SAN of the external storage that you want to migrate. Ensure that
your system is cabled and zoned into the same storage area network (SAN) as the external
storage system that you are migrating. If you are using Fibre Channel, connect the Fibre
Channel cables to the Fibre Channel ports in both canisters of your system, and then to the
Fibre Channel network. If you are using Fibre Channel over Ethernet (FCoE), connect
Ethernet cables to the 10 Gbps Ethernet ports.
