15 Frequently Asked Questions (FAQ)
Q: I created one volume, but my computer sees two of them.
Why?
A: There may be two Logical Unit Numbers (LUN) assigned to that
volume. To check this, use the GUI. Navigate to “Volume
Configuration” and then “Logical Unit”. If there are two Logical
Units for the same volume, hover your mouse over the button for
one of them in the “Host” column and click on “Detach.”
NOTE: You may still see two volumes until you restart your
computer.
Q: I’ve connected the RTX to my DHCP-enabled network
through the Config GUI port, but the LCD displays an IP
address that is not on my network and I cannot connect
to the GUI control panel using that IP address in my web
browser.
A: This may occur if you plugged in your cable into the Config GUI
port after the RTX Secure has already started up and initialized, or
if you previously configured the RTX Secure for a static network
or direct connection. The solution is to use the LCD interface
to obtain a DHCP address. Press “ENT”, then use the ▲(Up) or
▼(Down) arrows to scroll to the option “Change IP Config”. Press
“ENT”. The screen will say “DHCP”. Press “ENT”, then press the
▲(Up) arrow to select “Yes”. Press “ENT”. RTX will now attempt
to acquire a DHCP address. This new address will be displayed on
the main screen of the LCD.
Q: When I try to log on to the RTX Secure using the IP address
under the iSCSI configuration menu, nothing happens.
A: Sometimes when you first set up the RTX Secure you’ll need to
reattach the Logical Unit if it doesn’t work the first time.
Q: How many computers can connect to one data volume on
the iSCSI unit?
A: The short answer is one computer to one volume. This is the
safest and suggested usage of the RTX Secure. If two people
are accessing files on the same volume at the same time, there
is a very high chance that data corruption will occur. There are a
few file systems that can handle different users manipulating the
same volume, but they are not supported by Mac OS or Windows.
However, if the users connected to the volume have read-only
access, then corruption will not be an issue.
Q: When I make more than one volume, I still see all volumes
when connecting to the iSCSI IP address. How am I
supposed to allow only one person per volume if that’s
the case?
A: When you attach a Logical Unit to a Virtual Disk you’ll probably
notice a “Host” field with an asterisk as the default selection.
This means that any iSCSI Initiator will be able to connect to
that volume through that Virtual Disk. All iSCSI Initiators have
a unique name. You can use this name to restrict access to only
certain computers. For example, if my initiator is assigned the
name iqn.1991-05.com.microsoft:username01.crudataport.local,
and if I put that name into the host field when attaching a Logical
Unit, then only my specific computer will be able to connect to
that volume. You can use this to give one person read access and
everyone else write access by attaching two Logical Units to one
Virtual Disk.
Q: If I connect one computer to the RTX Secure and then
share the files from that computer, can more than one
computer access the files? Would the other computers
need iSCSI initiators installed on them?
A: One computer at a time can directly access the RTX Secure, but
files on the RTX Secure can be shared from that computer to other
computers. In such a scenario, the computer attached to the RTX
Secure acts as a server. Only the server computer requires an
iSCSI initiator. The other computers do not need special software.
Q: What is the difference between iSCSI and NAS (Network
Attached Storage)?
A: The difference between iSCSI and NAS is that a NAS does not
need a computer to act as a server.
Q: I put my computer to sleep, and now it’s having trouble
reconnecting to RTX. How can I prevent this?
A: To prevent difficulties such as this, follow the shutdown proce-
dure documented in the LCD menu diagram in Section 7.2.3. CRU-
DataPort also suggests that you disable automatic sleep on your
computer so it does not go into sleep mode without preparing the
RTX Secure for disconnection.
Q: Is there a way to use Bypass Mode on certain bays and use
an encryption mode on others?
A: There is no way to bypass individual bays and set others to use an
encryption key.
Q: The RTX is complaining that my RAID is degraded or failed,
and replacing disks does not solve the issue. Why?
A: Check the encryption mode to make sure that Unique Encrypted
Mode is selected. When the drives are encrypted with unique
encryption keys, but the RTX Secure is set to Common Encrypted
