Chapter 3: Creating and Configuring RAID Arrays

Configuring Logical Volumes 3-21

3.4 Configuring Logical Volumes

The Set/Delete Logical Volume screen provides access to the

following functionalities: Write Policy, Delete, and Partition.

The Write Policy options have previously been described.

The Delete button breaks down a configured volume. The logical

drives previously included within will then be individually configurable.

NOTE:

A logical volume can not be deleted if it has been associated with

host ID/LUNs. Remove the host LUN mappings before deleting a

logical configuration, either a logical drive or logical volume.

3.4.1 Create Partitions

IMPORTANT!

Unlike previous Galaxy, which has all of a volume’s capacity

defaulted as the first partition, “partition 0.” For the HDX4 DS

series, you need to create one or more partitions and map them

to host IDs. Create partitions according to the demands of users

and applications.

Another difference is that a partition can be expanded by drawing

free capacity in the logical volume without ill effects on other

partitions.
