Chapter 5: Concepts

As a result, there are range limits imposed upon logical drive expansion as shown in the table above. For example:

You can expand a 2.5 TB logical drive up to 4 TB

You can only expand a 1.9 TB logical drive up to 2 TB

See the table below.

You can direct WebPAM PRO or the CLU to expand a logical drive beyond the maximum expansion size. However, when expansion is finished, your logical drive will be the maximum size listed in the table.

If you require a logical drive larger than the maximum expansion size:

1.Backup the data from the current logical drive.

2.Delete the current logical drive.

3.Create a new logical drive with the desired capacity.

4.Restore the data to the new logical drive.

Caution

Before you begin logical drive Expansion or RAID Level Migration, always back up your important data.
