3ware 9550SX Serial ATA RAID Controller User Guide

Changing An Existing Configuration

With 3ware 9000 series RAID controllers you can convert one RAID 
configuration into another while the unit is online. This process is known as 
RAID Level Migration (RLM).

Note:

 Units on a 7xxx/8xxx series controller cannot be migrated.

 

 

You can use RAID Level Migration to make two main types of configuration 
changes:

„

RAID Level

„

Unit Capacity Expansion

You can also use RLM to change the stripe size of a unit.

These changes can be made using 3DM2 or the CLI. Instructions for using 
migrate in 3DM2 are described below. For information about CLI, see 

3ware 

9000 Series Serial ATA RAID Controller CLI Guide

.

This section includes the following topics about changing existing 
configurations:

RAID Level Migration (RLM) Overview

RAID level migration is the process of converting one RAID configuration to 
another. When you migrate a unit to a different configuration, the user data on 
it is redistributed to the format of the new configuration. This data 
redistribution process is a background task, similar to the rebuild or verify 
processes.

Figure 63 shows an example of how data is reconfigured during a migration. 
In this example, the migration is from a 4-drive RAID 0 to a 6-drive RAID 5, 
with both having the same stripe size. As can be seen, every piece of user data 
is moved from its original physical location.
