Terminology

RAID

Redundant Array of Independent Disks. There are different RAID levels with

different degrees of data protection, data availability, and performance.

JBOD

“Just a Bunch Of Disks”. JBOD needs at least one hard drive.

PD

Physical Disk. Belongs to the member disk of one specific RAID group.

RG

RAID Group. A collection of removable media. One RG consists of a set of

VDs and owns one RAID level attribute.

VD

Virtual Disk. Each RG could be divided into several VDs. The VDs from one

RG have the same RAID level, but may have different volume capacity.

LUN

Logical Unit Number. A unique identifier for a SCSI device which enables

computers to differentiate among separate SCSI devices.

GUI

Graphical User Interface.

RAID cell

The number of subgroups of PDs in an RG.

DS

Dedicated Spare disk. A spare disk dedicated to one specific RG and is used

when another disk in the RG fails.

GS

Global Spare disk. A spare disk that is shared among all RGs and is used

when another disk in an RG fails.

WWN

World Wide Name. A unique identifier that identifies a particular PD.

CHAP

Challenge Handshake Authentication Protocol. An optional security

mechanism to control access to RTX through its iSCSI data ports.

iSNS

Internet Storage Name Service. This protocol allows automated discovery,

management, and configuration of iSCSI devices on a TCP/IP network.

The main circuit boards of the HDD carriers are susceptible to static electricity. Proper grounding is

strongly recommended to prevent electrical damage to the enclosure or other connected devices,
including the computer host. Avoid all dramatic movement, tapping on the unit, and vibration.

Avoid placing the HDD carriers close to magnetic devices, high voltage devices, or near a heat

source. This includes any place where the product will be subject to direct sunlight. Do NOT allow
water to make contact with the carrier or receiving frame.

Before starting any type of hardware installation, ensure that all power switches have been turned off

and all power cords have been disconnected to prevent personal injury and damage to the hardware.

To avoid overheating, RTX should be operated in a well-ventilat ed ar ea and in suc h a way that

sufficient airflow is maintained across the controller chips.

RAID

Use only hard drives that are in perfect condition. Avoid using drives that have ever developed bad

sectors during previous usage. This could lead to possible device failure or loss of data.

RTX supports SATA hard drives of various specifications and different capacities. However, we

recommend using drives of the same brand and type for optimal performance. If drives of different
capacities are used in a RAID, the capacity of the smallest drive will determine how much of each
drive is used. The additional capacity on the larger drives will not be used by the RAID.

RAID level 0 will allow you to use the full combined capacity of the drives, and offers the best data

transfer speeds. However, RAID 0 offers no protection for the data. If one drive fails in a RAID 0, the
data on all of the drives is irretrievably lost. Before creating a RAID, investigate the various RAID
types and choose the one that is best for your needs.

Always back up data before switching RAID types. Switching RAID types will destroy current

data. You must reformat your drives afterwards.

A RAID (Redundant Array of Independent Disks) is an array of multiple hard drives that are combined in a
way that provides faster performance and/or data safety. Your RTX unit is capable of creating and
managing several different varieties of RAID. You may choose your preferred RAID level based on
factors such as disk capacity, desired data safety, and desired performance.

3.1 Summary of RAID Levels

RTX supports RAID Levels 0, 1, 3, 5, 6, 0+1, 10, 30, 50, 60, & JBOD. RAID Level 5 is most commonly
used by those seeking an optimal balance of speed and data safety.

4 Introduction to iSCSI

4.1 What is iSCSI?

iSCSI is a technology that allows a data storage device to be accessed over a TCP/IP network using
SCSI protocols. When your computer’s OS receives a request for data access, it generates a SCSI
command and then sends an IP packet across a network or direct Ethernet connection. A software utility
known as an iSCSI initiator is used to generate the SCSI commands. Such a utility must be installed on
the computer before it can access an iSCSI storage device (See Section 8 for installation instructions).

4.2 What is the Benefit of iSCSI?

An iSCSI storage device can be placed anywhere throughout a network, so the device can reside at a
great distance from the computer which accesses it. It is also a very fast connection when used on a
gigabit network, achieving speeds of 100 megabytes (MB)/sec or more. The connection it uses (RJ45—
standard Ethernet port) is commonly found on desktop and laptop computers, so there is no need to
purchase potentially expensive host bus adapters to provide a connection.

4.3 What is iSCSI Not?

iSCSI storage devices are not Network Attached Storage (NAS) devices. They have no built-in server
capabilities and therefore cannot be accessed by more than one computer at a time. Multiple computers
can only access the data if the iSCSI device is first attached to a single computer which is then set up as
a server.

5 Installation Steps

5.1 Hard Drive Installation

a) Pull the ejection handle on the TrayFree bay to open the bay door.
b) Insert a bare SATA hard drive into the bay. Make sure it is label-side up with the SATA connection on

the drive inserted first.

c) Shut the bay door.
d) You can optionally secure each bay door. Doing so is not necessary to operate RTX.

• For RTX410 and RTX610, Insert an RTX Key into its key lock and turn it 90 degrees clockwise.

• For RTX801-IR, use the Lock Tool to slide the lock to the “locked” position.

Sticker Card

Use the stickers on the provided sticker card to label each drive. This will prevent the drives from getting
mixed up when they are removed from the bays.

5.2 Operating RTX

a) Connect RTX to a computer or network using the included Ethern et cable. Plug one cable into the “CH-

1” port. You can optionally plug a second cable into the “CH-2” port. The purpose of having multiple iSCSI
channels is to provide redundancy/failover and increased performance.

b) Connect RTX to a power outlet with the included power cord.
c) Install the hard drives into RTX (See Section 5.1).
d) Flip the power switch on the rear of the unit to turn on RTX.
e) If you have not yet configured RTX for access, refer to Sections 6, 7, and 8. Section 6 will tell you how

to connect RTX to your network or computer. Section 7 contains instructions for accessing the GUI and

creating a usable RAID set. Section 8 contains instructions on how to access RTX through an iSCSI
initiator.

f) Format the drive. When a hard drive is first used with RTX, or when a RAID set has been created and
the user connects to RTX through an iSCSI initiator, it will show up as a blank, unallocated drive. You’ll
need to format the drive in RTX before you can use it See Section 9 for instructions on how to format the
drive with Mac or Windows operating s ystem s . Note that formatting a drive will erase all data on the

drive, so be sure to back up your data b efore installing the hard drives into this enclosure and
before beginning this operation.

5.3 Recovering from a Failed RAID

If one hard drive of a RAID set with data redundancy has failed or has been unplugged or removed, then
the status of the RAID Group will report that the RAID is degraded and RTX will automatically search for a
spare disk to rebuild the RAID. If none are found, RTX will search for a global spare disk. If neither is
found, it will wait for the user to remove the failed hard drive and insert a working replacement.

6 Network Configuration

6.1 Connecting RTX to Your Network or Computer

a) Plug an Ethernet cable into the Config GUI port on the rear of RTX.
b) Connect the other end of the Ethernet cable to your network. This usually means plugging it into a

router or hub. In an office environment, you may have a network jack built into your office wall. If a
network connection is not available, you can connect the Ethernet cable directly to an RJ45 (Ethernet)
port on your computer.

c) Connect the power cable to the rear of RTX and to a grounded electrical outlet.
d) Turn on RTX’s power using the switch on the rear panel.

6.2 Using the LCD to Configure the Config GUI Port

RTX has both an LCD interface and a GUI. The LCD interface has only basic functionality and is mainly
used to configure the IP address of the Config GUI port. Once the Config GUI has been configured, the
GUI can be used to fully configure RTX.

6.2.1 Navigating the LCD menu

Use the four function keys, ▲ (Up), ▼ (Down), ESC (Escape) and ENT (Enter) to manipulate the LCD
interface. After pressing ENT (Enter) key, you can use the ▲ (Up) and ▼ (Down) keys to select a
function. If there is an alarm or error message, the LCD will display the related information.

6.2.4 Instructions for Differi n g Network Connection Types

DHCP-Enabled Network

On DHCP networks, a new IP address is dynamically assigned to RTX’s Config GUI port as soon
as the network detects it. You can determine this address by checking the LCD interface on the
front of RTX. It will appear in this format: xxx.xxx.xxx.xxx. Simply type this IP address into a web
browser on your computer. This will access RTX’s GUI, which you will use to configure the unit.

Static Network
a) Check your computer’s IP address, subnet mask, and gateway. Mac users can find this

information in System Preferences  Network.

To do this in Windows, open Network and Sharing Center in the Control Panel (Also called “View
Network Status and Tasks” under the “Network and Internet” category). On the left pane, select
“Change adapter settings”. Right-click on your network (likely called Local Area Connection) and
select Properties. On the new window that opens, select “Internet Protocol Version 4 (TCP/IPv4)”
and click the Properties button. Your computer’s IP address, subnet mask, and gateway will be
displayed.

b) On the RTX LCD interface, press ENT and then scroll up or down to Change IP Setting.
Press ENT.

c) Scroll up or down to find Static. Press ENT.

d) Change the IP address to closely match what your computer is using. Or, if you are on a

business network, have your IT administrator assign you an IP address. The IP address you
select must NOT be in use by another device.

For example, if your computer's IP address is 192.168.0.9, you might change the RTX’s IP to

192.168.0.7. On smaller networks, each of the first three octets must be the identical to
your computer’s IP address! When changing the IP address you'll notice that a box flashes
over the digit to be changed. While the digit is selected, press ▲ (Up) or ▼ (Down) to change it.
Press ENT to move to the next digit.

e) After the IP address is set, enter the subnet mask address exactly as it is shown on your
computer’s TCP/IP settings.

f) Next, enter the gateway address exactly as it is shown on your computer’s TCP/IP settings.

g) Confirm the settings change. To confirm, press ▲ (Up) for “yes” and then press ENT again.

h) Type the RTX’s new IP address into a web browser on your computer. This will access the

RTX’s GUI, which you will use to configure the unit.

Direct Connection to a Computer

The instructions are similar to those for a static network (see above), except that your computer
will not have an IP address assigned if it’s not a part of a network. Since RTX and your computer
must have similar IP addresses, you will assign an IP address to your computer based upon the
default IP address of RTX.

a) Check RTX’s LCD to find out the IP address of the Config GUI configuration port. It will appear

After making changes

in this format: xxx.xxx.xxx.xxx.

b) Next, change your computer’s IP address so that all but the last three digits match RTX ’s
address. For example, if RTX’s IP address is 169.254.12.62, you might assign your computer the
number 169.254.12.63 (assuming no other computer on the network is already using that
number). The process of changing your computer’s IP address varies depending on its operating
system.

Mac users can go to System Preferences  Network.

For modern Windows operating systems, open Network and Sharing Center in the Control Panel
(Also called “View Network Status and Tasks” under the “Network and Internet” category). On the
left pane, select “Change adapter settings”. Right-click on your network (likely called Local Area
Connection) and select Properties. On the new window that opens, select “Internet Protocol
Version 4 (TCP/IPv4)” and click the Properties button. By default, your computer is probably set
to receive a new IP address automatically. Change the setting to manual configuration and then
type in the IP address.

c) Using the same process as the previous step, change the computer’s Subnet Mask setting to
match RTX’s Subnet Mask setting.

d) Finally, use RTX’s LCD interface to change RTX ’s Gateway setting. It should match the IP
address you assigned to your computer. When changing the gateway address you'll notice that a
box flashes over the digit to be changed. While the digit is selected, press ▲ (Up) or ▼ (Down) to
change it. Press ENT to move to the next digit. After the gateway address is set, press ENT all
the way to the end and confirm the settings change. To confirm, press ▲ (Up) for “yes” and then
press ENT again.

e) Launch a web browser and type RTX’s IP address into the URL bar, as if it were a website.
This will access RTX’s GUI, which you will use to configure the unit.

The tables below show example settings. The first table shows the type of settings that will
appear by default. The next table shows how the settings might look after you’ve made changes.

RTX Computer

Connecting From Home to Office

RTX can also be used over the Internet. If you are connecting to an RTX at your office from
home, you will need to contact your IT administrator to set up a VPN client in order to log in to the
office network. Once you have logged in to the office network, you can access RTX just as if you
were actually at your office (see instructions for DHCP-enabled Network, Static Network, or Direct
Connection to a Computer, depending on how your office network is configured).

7 Using the GUI

You will use the web browser-based GUI to set up a RAID and create logical volumes on RTX. After
setting up access to the GUI and accessing it through a web browser (see Section 6.2 for instructions),

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 10 -

CRU

the GUI’s main page should load, displaying a picture of RTX with several options to the left. When you
click on any option, you will be prompted for a username and password. The default administrator
username is "admin" and the default password is "1234."

7.1 GUI Indicators

The top right hand corner of the GUI window displays several indicators.

RAID light: Green indicates that the RAID is working properly. Red indicates a RAID error. If no

RAID is set up, the light will remain green.

Temperature light: Green indicates normal. Red indicates abnormal system temperature and

probable overheating.

Voltage light: Green indicates normal. Red indicates abnormal voltage status like a power surge

or a bad power supply.

Fan light: Green indicates that the fan is working properly. Red indicates a malfunctioning fan that

needs to be replaced. (only applies to RTX610-IR and 801-IR).

7.3 Manually Creating a Usable RAID Set

Use these sets of instructions to create a usable RAID set. To quickly create a RAID 0, 1, 3, 5, 6, or 0+1
set using the Volume Creation Wizard, see Section 7.6.1.

7.3.1 Manually Creating a RAID Group

To manually create a usable RAID set, you will first need to create a new RAID Group.

a) Click the “Create” button at the bottom of the page to open the RAID Group creation screen.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 12 -

CRU

b) Enter a name for the new RAID Group in the first field, and then select your desired RAID type or

JBOD from the dropdown box. CRU-DataPort recommends RAID 5 for maximum performance,
capacity, and security. For more information on RAID, see Section 3. Click “Select PD” to select
the drives that will be added to the RAID Group.

Note: Drives must be marked as Free Disks before they can be added to a RAID Group. To set
drives to Free Disks, see Section 7.7.2, subsection “Modifying Physical Disks”.

c) All available Free Disks will be displayed. Check the drives that you wish to add to the RAID

Group, then click “Confirm”.

d) The selected Physical Disks will now be displayed in the RAID Group creation screen. Enable or

Disable Write Cache, Standby, Readahead, and Command Queuing based on your needs. Most
RAID Groups will be fine with the default settings. Then click “Next” to proceed to the confirmation
screen.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 13 -

CRU

e) On the confirmation screen, verify that the RAID level is correct and all of the disks you selected

are displayed under “RAID PD slot”, then click “Confirm” to create the RAID Group.

f) The RAID Group will now display on the main RAID Group screen. To finish manually creating a

usable RAID set, a Virtual Disk still must be created and a Logical Unit must be attached. Go to
the next section, “Manually Creating a Virtual Disk”.

If you opted to create JBOD drives, skip to Section 8.3.3, “Manually Attaching a Logical Unit” as
Virtual Disks have already been created for each JBOD drive.

7.3.2 Manually Creating a Virtual Disk

After a RAID Group has been created, you can create associated Virtual Disks. You must create at least
one Virtual Disk to access the drives of RTX with a computer.

a) Click the “Create” button at the bottom of the page to open the Virtual Disk creation screen.

CRU

Name

Enter a name for the Virtual Disk.

RG Name

Choose the RAID Group to which the Virtual Disk will be added.

Capacity

Enter the capacity of the Virtual Disk. The default uses the maximum capacity of the associated
RAID Group. If you wish to create multiple Vir tual Disks on the selected RAID Group, you will
need to reduce the capacity below the maximum so that there is space left on the RAID Group for
additional Virtu al D is ks.

Stripe height (KB)

Determines how RTX organizes the RAID. Normally the default option is preferred.

Block size

Determines the minimum file size for files that will be stored on the Virtual Disk. Higher block
sizes can result in more wasted space if many small files are saved to the drive, but are
necessary to take advantage of high capacity RAIDs. If you are creating a Virtual Disk over

2TB in size for use with MacOS 10.4.x or older, or for use with Windows XP, you must
increase the block size to 4096KB to take advantage of the full capacity of the Virtual Disk.

Read/Write

Allows selection of cache type. Normally the default option is preferred.

Priority

Determines the priority that RTX will give to RAID activities (rebuild and initialization) versus
priority given to file transfers. “High prior ity” will result in slower file transfers during initialization,
but provide for faster initialization.

BG Rate

Background Task Priority. The higher the number, the more priority will be given to background
input/output.

Hover your mouse over the button in the “No.” column and click on “List connection.” It will list all the
connections of the session.

7.6.5 CHAP Account

CHAP (Challenge Handshake Authentication Protocol) is a common iSCSI authentication method. When
CHAP is enabled, RTX will require authenticatio n at login throu gh an iSCSI initiator (see Section 8).
Authentication also occurs at various times during the connection, by way of transferring the username,
initiator password (also called “initiator secret”), and target password (also called “target secret”). RTX
uses the same value for initiator secret and target secret. For added security, the authentication
information is hashed and a token is sent instead of the information itself.

If any disks are not assigned to a Virtual Disk, it will walk you through a series of steps to create a usable
RAID set. If there are previous RAID Group or Virtual Disk configurations present, the wizard may limit the
choices you can select in the following steps.

a) Select your desired RAID Level from the drop-down box, then click the “Next” button. The drop-

down box displays the drive capacity next the RAID Level.

b) Choose how many disks you wish to use in the new RAID Group. The default algorithm uses all

of the disks not already assigned to a RAID Group. Or you can choose how many disks you want
the new RAID Group to use by selecting the “Customization” radio button and then using the
drop-down box to select the number of disks. The drop-down box displays the drive capacity next
the number of disks.

8 iSCSI Initiator Software

8.1 Software Installation

This is a required step. Any computer must have initiator software installed before it can connect to an
iSCSI device such as RTX. Both freeware and commercial software utilities are available for this purpose.

Note: Initiator software is not required for additional computers that share files with the host computer
attached to RTX. In such a scenario, the host computer acts as a server to the other computers. Only the
computer directly accessing RTX needs initiator software.

8.1.1 Windows

Windows Vista and 7 alread y include the i SCSI sof twar e, no downlo ad is neces sa ry.
If necessary, users can download free Microsoft iSCSI Initiator software at the following URL:

9 Usage with Mac and Windows Operating Systems

9.1 Usage with Mac OS X

9.1.1 Compatibility

RTX supports 3.5” SATA hard drives.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 37 -

CRU

9.1.2 Formatting a Drive

To format, use Mac OS X’s Disk Utility (found in the applications folder).

a) Click on the drive in the window to the left (see picture below).
b) Click the Erase tab in the window to the right (see picture below).
c) Select the format type. Most users prefer Mac OS Extended with Journaling (HFS+), which is required

for compatibility with Time Machine (OS 10.5 or newer). If you need to use RTX with both Mac and
Windows computers, select MS-DOS File System instead.

d) Enter a name for the new volume and then click “Erase” to start the process.

9.1.3 Mounting and Unmounting Volumes
Mounting Volumes

If the hard drives installed in RTX are already formatted with the correct Security Key inserted into the
Mini-USB Security Key Port, an icon representing RTX ’s volume will appear (mount) on the desktop. You
can begin using the volume right away. If the volume is unformatted, a message will appear on the
desktop saying that the disk is unreadable. Use OS X’s Disk Utility to easily format the drive (see section
above).

Unmounting Volumes
First, eject the data volume by dragging the volume’s icon to the trash bin, or by
selecting the icon then pressing Command-E. Next, log off the volume in your
iSCSI initiator software. If you are using the globalSAN initiator, you log off from
the “Targets” tab. Disconnecting in this way allows you to reconnect quickly later.
Another way of preventing delays is to keep your iSCSI initiator software open at
all times. You can minimize it and allow it to run in the background. Closing the
software and then reopening it can cause a lengthy delay before access to RTX
is allowed.

NOTE: It is strongly suggested that you disable automatic sleep mode on your Mac. You can still put the
Mac to sleep manually at any time as long as you follow the above procedures. This will prevent
reconnection difficulti es.

9.1.4 Creating a Boot Drive

To activate this feature, you must first install OS X on the volume in RTX. The easiest way to do this is to
clone an existing system drive using a utility such as Carbon Copy Cloner or Super Duper. Next, go to
System Preferences  Startup Disk. A window will list the available bootable volumes. Select the volume
from which you wish to boot. Another method is to hold down the Option key during boot up. A screen
should appear that allows you to select the volume you wish to use. This is useful if you wish to boot from
RTX hard drive only some of the time.

9.2 Usage with Windows Operating Systems

9.2.1 Compatibility: RTX supports 3.5” hard drives.

9.2.2 Formatting a Drive: To format, use the Disk Management utility.
a) Right-click on My Computer, then select Manage. The Computer Management window will open.

b) In the left pane of this window, left-click on Disk Management.

c) The volume should appear in the list of Disks in the lower middle/right pane (see picture below). You

may need to scroll down to see it. If the volume is already formatted, you can identify it easily by its
volume name. If it’s unformatted, the Drive Properties Box will say “Unallocated” and
you’ll need to initialize the disk before formatting it. Initialize the disk by right-clicking the Device
Properties Box and selecting Initialize Disk.

d). To format the volume, right-click the Drive Properties Box and select “Format”.
e) If you are prompted to select a partition type, select MBR for volumes 2TB or smaller, or GPT for

volumes larger than 2TB. Note: Windows XP does not support GPT or volumes larger than 2TB.
f) Click through several more windows, leaving the default settings (unless you need to change them),

until you see a window that allows selection of a file system. Choose NTFS and enter a name for the new
volume. Be sure to check the box labeled “Perform a quick format” unless you want to completely erase
any data on the drive and have time to wait. A quick format should take less than a minute, while
standard formatting may take several hours.

g) Click “Next” and then “Finish” to start the format process. When the format is complete, the Drive
Properties Box will update to show the new volume name. The new volume can now be found by double
clicking on the My Computer icon on the desktop.

9.2.3 Mounting and Unmounting Volumes
Mounting Volumes

If the hard drives inside of RTX are already formatted with the correct Secur i t y Key inserted into the Mini­USB Security Key Port, you can begin using the volume right away. When RTX is properly connected
and turned on, a window may open to allow you access to the volume. If no window appears, find the
volume by double-clicking the “My Computer” icon.

Unmounting Volumes
Log off the volume using your iSCSI initiator software. In the Microsoft initiator, you can log off from the
“Targets” tab.

10 RAID Is Not a Backup

Because RTX features redundant RAID modes which protect against a hard drive mechanical failure, it is
an excellent part of any backup strategy. However, a RAID is not, in itself, a complete backup strategy.
Many things besides hard drive failure can damage or erase your data:

• Corruption caused by unexpected disconnection during data access (e.g. a cable is unplugged
during a data transfer, or the computer crashes or loses power while writing to the drives)

• Corruption or destruction caused by viruses or other malware

• Sabotage by a disgruntled employee or acquaintance

• Theft of your RTX

• Natural disasters such as fire, flooding, etc.

Considering these possibilities, any single copy of your important data must always be considered at risk.
That's why backing up is so important. Follow the 3-2-1 backup rule. Data should exist in three different
places on two different storage media and at least one of those copies should be maintained offsite.
Without an effective backup strategy, recovering data may be impossible, or the cost of data recovery
may be quite expensive. The CRU warranty does not cover costs associated with data loss (nor do the
warranties of other hard drive manufacturers).

Plan accordingly and backup data to minimize downtime!

12 Working With Volumes Over 2TB in Size

Although RTX can create data volumes larger than 2TB, some older operating systems cannot access
such volumes. This is because they support only 32-bit LBA (Logical Block Addressing).
Newer operating systems should be able to use 2TB+ volumes without difficulty. You will simply need to
do one of the following two things while creating a Virtual Disk:

• Change the LBA to 64-bit

• Increase the block size to 4096

Windows

Neither of the options above will work for operating systems older than Windows XP. You need to make
more than one Virtual Disk, each less than 2TB in size. Each Virtual Disk also needs a different LUN.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 44 -

CRU

Mac OS

Although Mac OS 10.4.x supports only 32-bit LBA, increasing the block size to 4096 will allow you to
create a 2TB+ volume that is usable by the OS.

Linux

Versions of Linux vary, but using one of the above methods may allow you to create a 2TB+ volume that
your distribution can use.

13 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 hooked up the Config GUI port to my DHCP-enabled network, 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 the Config GUI after RTX has already started up and initialized, or if

you previously configured RTX 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 RTX using the IP address under the iSCSI configuration menu, nothing

happens.

A Sometimes when you first set up RTX 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 RTX. 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.199105.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 RTX 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?

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 45 -

CRU

A One computer at a time can directly access RTX, but files on RTX can be shared from that computer to

other computers. In such a scenario, the computer attached to RTX 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 procedure documented in the LCD menu

diagram in Section 6.2.3. CRU-DataPort also suggests that you disable automatic sleep on your
computer so it does not go into sleep mode without preparing RTX for disconnection.
