Array migration for storage using Linux


Array migration for storage using Linux
Prev	Migrating storage arrays	Next

The array migration example documented for this use case uses a Linux system. The example details would be different for AIX, Solaris, or Windows systems.

Storage Foundation and High Availability Solutions (SFHA Solutions) products provide enterprise-class software tools which enable companies to achieve data management goals which would otherwise require more expensive hardware or time-consuming consultative solutions.

For many organizations, both large and small, storage arrays tend to serve as useful storage repositories for periods of 3-6 years. Companies are constantly evaluating new storage solutions in their efforts to drive down costs, improve performance and increase capacity. The flexibility of Storage Foundation and High Availability Solutions enable efficient migration to new storage and improve the overall availability of data.

While there are several methods for accomplishing the migration, the most basic and traditional method is using a volume level mirror. The example procedures:

Provide system administrators responsible for SFHA Solutions systems within their organization a demonstration of the steps required for performing an online storage array migration from one array to another.
Illustrate the migration process using a Linux system which is connected to two different storage arrays through a SAN.
Provide steps for starting with a file system with a single volume, mirroring the volume to a volume to another array, and then detaching the original storage.
Are performed from the command prompt.
Use Operating System Based Naming (OSN) for disk devices (sdb, sdc, etc).

There are two user interface options:

The SFHA Solutions command line interface (CLI).
The Veritas InfoScale Operations Manager graphical user interface (GUI) has a storage migration wizard.

See the Veritas InfoScale Operations Manager documentation for details:

Note:

Veritas NetBackup PureDisk comes bundled with the Storage Foundation and High Availability Solutions software for the purpose of enhanced storage management and high availability. Storage arrays used with PureDisk can also be migrated using the SFHA Solutions methodologies.
