Advanced Setup of Physical Devices
The Physical Devices page allows you to manage attached disk and RAID storage devices
similar to the Logical Volume Manger level and requires a detailed knowledge of UNIX system
administration and the Logical Volume Manager.
Caution: Use of the Advanced Setup Tools functions requires you to use Command View
SDM to create and manage LUNs. Incorrect use of the Advanced Setup tools can result in
data loss.
From the NAS web interface Storage tab, navigate to Advanced Setup > Local Storage and
select Physical Devices.
The main grid on this page will display all physical storage devices attached to the server, their
connection path, size, and associated Volume Group. Two checkboxes control the presentation
of this display for attached RAID devices.

are normally added to a LVM Volume Group (new or existing) as a physical volume. Logical
Volumes are then created on the physical volume, and file systems then created on the Logical
Volumes. File systems may then be shared with external computer systems via NFS or CIFS.
