Adding a Storage Policy

remains on disk after data blocks are freed during policy management or space management.

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

Disk-to-Disk Relocation (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-diskrelocation, 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 Managing the File System on page 80.)

•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.
