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 -
Page 11
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 -
Page 13
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 -
Page 14
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.
b) You will see the screen below. Fill in the information and then click “Confirm”. Each field is
explained below the picture.

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.

7.6.4 Session
The session function allows you to view information on a session initiated by an iSCSI initiator application (see Section 8), including Initiator Name, TPGT, Error Recovery Level, and Error Recovery Count.
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.
a) To use CHAP, you will need to turn on CHAP authentication (see Section 7.6.3) and then follow
the steps there to set up a CHA P account.
b) After clicking on the “CHAP Account” option, you will see the following screen:
Click “Create” to create a new user. This brings up a screen with fields for User, Secret, and Confirm. Enter a user name in the first field, and a 12-16 character password to use as the secret in the second and third fields. Click the “Confirm” button.

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.
On the next screen, fill in the size in MB for how large you want the new RAID Group to be, then click the “Next” button. The maximum size is filled in by the wizard automatically, so in most cases you simply need to click the “Next” button.
Step 4 summarizes the choices you have made. If anything is incorrect, select the “Back” button and navigate backwards through the steps to change your options. If everything looks fine, click “Confirm.” The GUI will navigate to the Virtual Disk page which now shows a new Virtual Disk with the name similar to “QUICK#####”.

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:
http://www.microsoft.com/download/en/details.aspx?id=18986

8.2 Access RTX using iSCSI Initiator Software
This software can by launched by doubl e-clicking on the iSCSI Initiator icon in the Administrative Tools folder in the Control Panel.
8.2.1 Windows XP After you launch the initiator you'll see a windo w with s evera l tabs , with the "Gen eral" tab opened by default. a) If you have set up CHAP in the RTX GUI, input the proper information by clicking on “General” tab and then clicking on the “Secret” button.
b) Select the "Discovery" tab. Under Target Portals, click the "Add" button and enter the IP address for the RTX’s CH-1 or CH-2 port (depending which connection link is shown as “Up” on the NIC screen).
c) Next, select the "Targets" tab. You should see a selection for the RTX in this Targets tab. d) Select that target and click "Log on." Leave the default settings alone and click “OK”.
If the log-on is successful you'll now be able to use the RTX just like any other disk attached to your computer.
8.2.2 Windows Vista and Windows 7 a) After you launch the initiator, input the IP address for the RTX’s CH-1 or CH-2 port (depending which
connection link is shown as “Up” on the NIC screen. b) Click on the “Quick Connect…” button.
If the log-on is successful you'll now be able to use the RTX just like any other disk attached to your computer.
Note: The Quick Connect feature does not support advanced connection types like CHAP. For instructions on connecting to an iSCSI target using advanced settings, visit the following URL:
http://technet.microsoft.com/en-us/library/ee338480(v=ws.10).aspx#BKMK_ConnectAdvanced
8.2.3 GlobalSAN iSCSI Initiator for MacOS This software can be launched by double-clicking on the globalSAN iSCSI icon in System Preferences.
a) After you launch the initiator you’ll see the globalSAN window pop up. Press the Add button (“+”) and
choose Portal from the dropdown menu to add a new portal. b) On the Add Portal dialog box, enter the IP address for the RTX’s CH-1 or CH-2 port depending which
connection link is shown as “Up” on the NIC screen, and then click OK. c) If you have set up CHAP in the RTX GUI input the proper information by clicking on the “Authentication
Settings” button. d) Select the new target in the list to the left, then select the appropriate connection from the list that
opens up on the right side and click the “Connect” button. If the log-on is successful you'll now be able to use the RTX just like any other disk attached to your computer.
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 -
Page 38
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.

Drive Properties
Device Properties
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 -
Page 45
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 -
Page 46
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.
