IBM Flex System V7000 Storage Node Introduction and Implementation Guide

In this section, we show you how to prepare external storage systems and IBM Flex System 
V7000 Storage Node for data migration. Data migration is always an important step when 
setting up new storage systems in an existing storage infrastructure.

Before attaching any external storage systems to IBM Flex System V7000 Storage Node, see 
the IBM Flex System V7000 Storage Node support matrix at the following address:

http://www-947.ibm.com/support/entry/portal/overview/hardware/puresystems/pureflex
_system/storage_node/flex_system_v7000

Also always check for supported hardware and driver versions at IBM System Storage 
Interoperation Center (SSIC):

Also available is the IBM Flex System Interoperability Guide, REDP-FSIG which is a Quick 
reference for IBM Flex System Interoperability.

When migrating data from an external storage system to the IBM Flex System V7000 Storage 
Node, where the external storage system is removed when complete, you can temporarily 
configure the external virtualization license setting. Configuring the external license setting 
prevents messages from being sent that indicate that you are in violation of the license 
agreement. When the migration is complete, the external virtualization license must be reset 
to its original limit. 

To prepare the data migration, external storage systems need to be configured to be under 
IBM Flex System V7000 Storage Node control. Complete the following steps:

1. Stop host I/O to the external storage LUNs that need to be migrated.

2. Remove zones between the hosts and the storage system from which you are migrating.

3. Update your host device drivers, including your multipath driver, and configure them for 

attachment to the IBM Flex System V7000 Storage Node system.

4. Create a storage system zone between the storage system being migrated and IBM Flex 

System V7000 Storage Node system, and the host zones for the host attachment.

5. Unmap the LUNs in the external storage system to the host and map them to the IBM Flex 

System V7000 Storage Node system.

6. Verify that the IBM Flex System V7000 Storage Node has discovered the LUNs as 

unmanaged MDisks.

In this section, we describe how to migrate existing data on external storage systems using 
the IBM Flex System V7000 Storage Node storage migration wizard.

We use the IBM Flex System V7000 Storage Node wizard that has been designed specifically 
for this scenario to guide you through the process and describe the steps along the way.

External storage: When external storage is virtualized by IBM Flex System V7000 
Storage Node, a per-enclosure external virtualization license is required. Contact your IBM 
account team or IBM Business Partner for further assistance, if required.
