DESCRIPTION
Select this check box and an option from the drop-down list box to encrypt
the volume. This option is only available when you create a volume using
the xfs file system.
The NSA automatically locks an encrypted volume if the NSA restarts or
loses power or the disk is removed. An administrator can also manually
lock the volume. Once a volume is locked, no one can use it again until an
administrator unlocks it.
password: Select this option to manually enter a password for unlocking
this volume. You can also enter a password prompt. You will need to
manually re-enter the key every time the NSA restarts.
USB key: Select this option to have the NSA create a password for
unlocking the volume and store the password on (another) connected
USB device. Note that if the volume is later locked, the NSA automatically
unlocks it if the USB device containing the key is inserted when the NSA
restarts.
At start up, if a USB key is inserted, the NSA automatically unlocks any
volumes encrypted by it.
The password fields display if you choose to encrypt the volume by
manually entering a password. Enter a password for encrypting the
volume.
Re-type the password to make sure you entered it correctly.
Enter a hint to help you recall the password if you forget it.
The USB field and button display if you choose to encrypt the volume by
USB key. Select a USB key device that you created previously or select a
USB device that you want to make into a USB key.
If the USB device is not already connected, connect it and click the
Refresh icon.
The NSA's upper USB port is USB1 and its lower USB port is USB2.
It is recommended that you use a USB device to store a volume key only
and not also use it for storage.
Click this button to go to screens you can use to create a password for
unlocking the volume and store the password on a connected USB
device. You also use the screens to create copies of the USB key. See
Section 6.6.2 on page 144 for details.
Note: Create duplicate USB keys now since you cannot
make them later. Without a USB key, you cannot
access the volume if it becomes locked. All of the
volume's data will be unusable.
Click this button to save your changes back to the NSA.
Click this button to discard your changes and close this screen.
