Mutual Authentication
The iSCSI TeraStation supports mutual authentication for security. Mutual authentication lets a computer
only recognize a TeraStation when the mutual password set on each volume and the mutual authentication
password match. To congure mutual authentication, turn to page 26.
Mutual Authentication password set to the TeraStation (Entire system):
Select “Basic"-”Security” in the conguration utility, and click “Mutual Authentication" from “Access Control" in
“Access Control (Whole System)”. If the password set on the computer matches the volume name in “Volume”,
the iSCSI Hard Disk Connection Tool will be functional.
Note: If the volume name is not displayed in the “Volume” eld, then the mutual authentication password on the
computer does not match. In such a case, select “Setup”, then “Set Mutual CHAP Secret” from in the iSCSI Hard
Disk Connection Tool menu to enter the correct password. Click “Refresh”.
Mutual Authentication password set to each volume:
In the TeraStation Conguration utility, click on “iSCSI Volumes”, then “iSCSI Volumes”. In “Access Control”, click
“Mutual Authentication" and set Password (Mutual Authentication).
The password set here is used to connect to the volume. The mutual authentication password on the computer
must be set to connect to the volume.
Mutual Authentication password set on the Computer Side
If you congure mutual authentication on a TeraStation or individual volumes, enter the same password as you
set on the TeraStation for access restrictions for each volume on the mutual authentication password screen.
The password you entered is maintained as a mutual authentication password on the computer. If there are
multiple volumes, the computer will connect to the volume which has the correct password. You cannot
connect to multiple volumes with different mutual authentication passwords. To connect to a volume with a
different password, you must change the password in the iSCSI Hard Disk Connection Tool menu.
Note: If the mutual authentication password of the TeraStation and that of the volume are different, the volume name
will not be displayed on the main screen in the iSCSI Hard Disk Connection Tool. Select “Setup”, “Set Mutual
CHAP Secret”, “Refresh” to enter the matching password.
