Notes:
• If shared folders are created in LVM volumes, the antivirus software may not work properly. For best results,
disable LVM before use.
• If you click Show under "Volume List", the volumes will be listed on the screen and you can see if these volumes
are being used as iSCSI or NAS.
• If an LVM volume could not be mounted, try restarting the TeraStation. If an issue still exists, delete and recreate
the LVM volume. Deleting the LVM volume will erase data on the volume.

Using the TeraStation as an iSCSI Device

Introduction

iSCSI is a protocol for carrying SCSI commands over IP networks. Unlike traditional SAN protocols such as Fibre
Channel, which requires special-purpose cabling, iSCSI can be run over long distances using existing network
infrastructure. Normal Windows formatting such as NTFS is supported.
Differences Between NAS and iSCSI
With iSCSI, the TeraStation is connected to a single computer, such as a server. Other computers on the network
access files on the TeraStation through the computer it's connected to. The TeraStation can be used as a local drive
from Windows Server. Features of Windows Server such as Active Directory can be used normally.
As a NAS, the TeraStation is a server, and computers (including other servers) on the network can access shared
folders on it directly. A separate server is not required, and features such as backup are built-in.
Network Configuration
Use gigabit or faster network equipment with iSCSI. For best results, a dedicated network for iSCSI is recommended,
separate from the regular network. By default, the IP address of the TeraStation is automatically assigned from a
DHCP server. However, in this case, if you turn off and restart the TeraStation, the IP address may be changed and
the volumes on the TeraStation may not be accessible. To avoid changing the IP address unexpectedly, using a static
IP address for the TeraStation is recommended.
Connection Tool
Windows XP, Windows Server 2003
Before using any iSCSI equipments, download and install the iSCSI connection software "Microsoft iSCSI Software
Initiator" from the Microsoft website. If using TeraStation 5000 series, you can also use Buffalo iSCSI Connection Tool
to connect an iSCSI drive.
Windows Vista or later, Windows Server 2008 or later
The Microsoft iSCSI Software Initiator is already installed on your computer. You don't need to download and install
it. If using TeraStation 5000 series, you can also use Buffalo iSCSI Connection Tool to connect an iSCSI drive on except
for Windows 10. If you are using Windows 10, use Microsoft iSCSI Software Initiator.

Creating an iSCSI Volume

To use the TeraStation as an iSCSI drive, create a volume first. Configure the TeraStation as described below.
