Disk-to-Disk relocation allows you to move data from one set of disks 

(disk stripe group) to another without affecting the file name space. You 

can perform this procedure only if you have the full StorNext suite. 

(Customers with StorNext File System only cannot perform this 

procedure.)
Before enabling disk-to-disk relocation, you must perform these 

preliminary tasks if you have not already done so:

• Create a new managed file system with no more than two affinities, 

or reconfigure an existing managed file system by adding affinities. 

(For instructions on creating the file system, see 

 on page 82.)

• Create a policy class or modify an existing one.
• Create a relation point.
• Determine relocation criteria. 

After you have accomplished these preliminary tasks, you can enable 

disk-to-disk relocation.

Adding a Storage Policy

Use the following procedure to add a new storage policy. When you 

create the policy, you can enable disk-to-disk relocation, stub file support, 

or both features.
