42 Chapter 3 Managing SAN Storage
Adding Storage
There are several ways you can add storage to a SAN:
• Add RAID arrays (LUNs) to existing storage pools
• Add storage pools to existing volumes
• Add new volumes
The first method requires you to unmount and remount the volume on clients.
The second method lets you increase the available space in an existing SAN volume
without interrupting users who are using the volume. The only change users notice is
additional space available on the volume.
The third option creates a new volume that must be explicitly mounted on client
computers. Clients must then choose to save new files and folders on the new volume,
or copy existing items there, so this option is more likely to disrupt user workflow.
