Dynamic Growth

Dynamic growth is a feature of the NAS 2000s, which provides for growth of a volume or
partition to meet expanding storage requirements without the need to take volumes offline or
incur downtime. Growth may occur in three forms:

Expanding a LUN

Expanding an existing LUN is accomplished via the Array Configuration Utility presented on
the Disk page. LUN expansion may occur in Disk Arrays where space is available. If
insufficient space is available, additional physical disks may be added to the array
dynamically.

Option
Extend unallocated space from original LUNS.
Alter LUNs to contain additional storage.
Add new LUNS to the system. The additional space is then extended into through a variety
of means depending on which type of disk structure is in use.
Opens a page to extend a partition based on a basic disk
or it opens Windows Disk Management to extend dynamic
based volumes.
Select to detect a volume or partition added to the system or
to update the size of a volume that has undergone
expansion. The rescan is not synchronous and may require a
browser refresh after the scan is initiated to display the new
content.
Select to open the Windows Disk Manager and perform
advanced volume management tasks.
