Preparing for Volume Expansion
NOTE: This procedure does not apply to the PERC 3/Di controller, which is the integrated RAID controller on
PowerVault 775N NAS systems.
NOTE: You cannot expand system volumes in an internal RAID group.
The NAS Manager allows you to expand volumes, while retaining the same fault tolerance level. However, a volume must be
prepared before it is expanded. During preparation, the original volume is still accessible.
NOTE: See " Advanced Disk and Volume Management " for advanced operations on all RAID controllers.
To prepare a volume for expansion, perform the following steps:
1. Log in to the NAS Manager.
2. Click Disks.
3. Click Volumes.
4. In the Volumes column, select the volume to prepare for expansion by clicking the adjacent radio button.
