Chapter 1: Introduction to RAID

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.

Summary of RAID Levels

The RTX supports RAID Levels 0, 1, (0+1), 3, 5 and 6. RAID level 5 is most commonly used by those
seeking an optimal balance of speed and data safety.

Level

Also known as striping. Data distributed
across multiple drives in the array. There is
no data protection.
Also known as mirroring. All data replicated
on separated disks. RAID 1 is almost always
2 disks.
This is a high availability solution, but due to
the 100% duplication, it is also a costly
solution.
Also known as Block-Interleaved Parity.
Data and parity information is subdivided
and distributed across all disks. Parity must
be equal to the smallest disk capacity in the
array. Parity information normally stored on
a dedicated parity disk.
Also known as Bit-Interleaved Parity. Data
and parity information is subdivided and
distributed across all disks. Parity must be
equal to the smallest disk capacity in the
array. Parity information normally stored on
a dedicated parity disk.
Also known as Block-Interleaved Distributed
Parity. Data and parity information is
subdivided and distributed across all disks.
Can withstand the failure of one drive, and
80& of drive capacity is usable.
Two different parity bits are used, to create
double redundancy. Can withstand the
failure of two drives, but only 60% of drive
capacity is usable.

Chapter 2: Introduction to iSCSI

2.1 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.

2.2 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 100MB/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.

2.3 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.

Chapter 3: Pre-Installation

3.1 Install iSCSI Initiator software on your computer.

This is a required step. Any computer must have Initiator software installed before it can connect to an
iSCSI device such as the RTX-IR. 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 the RTX. In such a scenario, the host computer acts as a server to the other
computers. Only the computer directly accessing the RTX needs Initiator software.

Windows

Users can download free Microsoft iSCSI initiator software at the following URL:

http://www.microsoft.com/downloads/details.aspx?FamilyID=12cb3c1a-15d6-4585-b385­befd1319f825&DisplayLang=en

Chapter 4: Hard Drive Installation

If you purchased your RTX with pre-configured drives, you may skip to the next section.

Install a SATA (Serial-ATA) hard drive into each bay. With TrayFree™ technology, this

process couldn’t be easier! Simply pull the ejection handle to open the bay door, slide in your SATA
drive, and shut the door behind it. The drive is inserted with the label up and the SATA connection on the
drive inserted first. With the RTX400 & RTX600H, you can lock the bay for additional security, but make
sure to unlock it before pulling on the ejection handle again.

NOTE: If any of the drives are inaccessible after
powering on the unit, try the following steps:

1. Turn off the power.

2. Remove the drive(s) in question.

3. Reinsert the drive(s).

4. Turn on the power.

Chapter 5: Configuration

5.1 Connect the RTX to your network (or computer) for configuration.

a. Plug an ethernet cable into the “LAN GUI” port on the rear of the RTX.

b. Connect the other end of the ethernet cable to your network. Usually, this 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 the RTX and to a grounded electrical outlet.
d. Turn on the RTX unit’s power using the switch on the rear panel.

5.2 Use the LCD to configure the LAN 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 LAN GUI port. Once the LAN GUI has been configured, the GUI
can be used to fully configure the RTX.

5.2.1 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.

5.2.4 If you are connected to a DHCP-enabled network

On DHCP networks, a new IP address is dynamically assigned to the RTX’s LAN GUI port as soon as the
network detects it. You can determine this address by checking the LCD interface on the front of the
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 the RTX’s GUI, which you will use to configure the unit.

5.2.5 If you are connected to a static network

a. Check your computer’s IP address. To do this in Windows, open Network Connections in the Control

Panel. Double-click on your network and then click on the Support tab. Your computer’s IP address will
be displayed. Mac users can find this information in System Preferences  Network.

b. On the RTX’s 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. For example, if your computer's

IP address is 192.168.000.009 you could change the RTX's IP to 192.168.000.007. Everything but the
last set of three digits must be the same! 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. After the IP 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. Type the RTX’s new IP address into a web browser
on your computer. This will access the RTX’s GUI,

have? If the IP address displayed on the
LCD starts with 169.254 or 192.168, this
indicates that the network is probably not
DHCP-enabled. Use the instructions for
a static network.

which you will use to configure the unit.

5.2.6 If you are connected directly to a computer

The instructions are similar to those for a static network (see 5.2.2), except that your computer will not
have IP address assigned if it’s not a part of a network. Since the RTX and your computer must have
similar IP addresses, you will assign an IP address to your computer based on the default IP address of
the RTX.
a. Check the RTX’s LCD to find out the IP address of the LAN GUI configuration port. It will appear in this
format: xxx.xxx.xxx.xxx.
b. Next, change your computer’s IP address so that all but the last three digits match the RTX’s address.
For example, if the RTX’s IP 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. (For Windows XP,
open Network Connections in the Control Panel. Right-click on your network and select Properties. On
the new window that opens, select TCP/IP and click the Properties button. Mac users can go to System
Preferences  Network.) 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 Mask setting to match the RTX’s
Mask setting.
d. Finally, use the RTX’s LCD interface to change the RTX’s Gateway setting. It should match the IP
address you assigned to your computer.
e. Launch a web browser and type the RTX’s IP address into the URL bar, as if it were a website. This
will access the RTX’s GUI, which you will use to configure the unit.

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

5.2.7 If you are connecting from home to office

RTX-IR can also be used over the internet. If you are connecting to an RTX-IR at your office from home,
you will need to contact your IT administrator to set up a VPN client to log in to the office network. Once
you have logged in to the office network, you can access the RTX-IR just as if you were actually at your
office (see section 5.2.4 or 5.2.5, depending on how your office network is configured).

5.2.8 If you are connecting from office to home

Most home networks are configured with a router to allow multiple computers to share an internet
connection. In this case, you will need to set up your router to forward port 3260 to the RTX-IR. This
process varies depending on the router you are using, so consult your router’s user documentation or
contact the manufacturer if you have difficulties. The iSCSI initiator should be set to contact the public IP
address of your cable modem.

Chapter 6: Using the GUI

You will use the web browser-based GUI to set up a RAID and create logical volumes on the RTX. After
accessing the GUI (see step 5.2), the GUI’s main page should load, displaying a picture of the RTX with
several options to the left. When you click on any option, you will be prompted for a user name and
password. The user name is "admin" and the default password is "1234."

Some information is obscured for security reasons

WiebeTech LLC

• Name: LAN1/LAN2. LAN1 corresponds to the port labeled CH-1 on the back of the RTX-IR, while
LAN2 corresponds to the port labeled CH-2.

• DHCP: Yes/No – Click on the button below “Yes” or “No” to configure the IP settings for each
data port. Refer to section _____ for more information.

• IP address: Displays the IP address currently in use by each data port.

• Netmask: Displays the subnet mask being used by each data port.

• Gateway: Displays the IP gateway (in a DHCP network, the IP of the router)

• MTU (Maximum Transmission Unit): Displays the MTU size being used by each data port. The

range of MTUs allowed are 1500, 2000, and 3900. Default is 1500. To change the MTU, click
the button below the current MTU number of the LAN port that you wish to alter. This will bring
up a screen with a dropdown box that can be used to change the MTU.

Note: Changing the MTU will cause the RTX-IR to function improperly if the switch and network
card are not configured appropriately.

• MAC address: Displays the MAC address of each data port.

• Link: Up/Down – Displays the status of each data port. If an Ethernet cable is connecting the

RTX-IR to a network or computer, the Link will display “up.”

6.5.3 Node

The Node option displays the RTX-IR’s entity name, which will be seen by the iSCSI initiator, and allows
you to toggle CHAP (Challenge Handshake Authorization Protocol) on or off. For more information on
CHAP, see 6.5.5.

CHAP is disabled by default. To turn on CHAP, click the button in the Auth column. This will bring up a
screen with a dropdown box. Click the dropdown box and select CHAP, then click the Confirm button.

After turning on CHAP authentication, you must set up at least one CHAP account (see section 6.5.5).

6.5.4 Session

The session function allows you to view information on a session initiated by an iSCSI initiator application
(see Chapter 7.)

6.5.5 CHAP account

CHAP is a common iSCSI authentication method. When CHAP is enabled, the RTX-IR will require
authentication at login through the iSCSI initiator (see Chapter 7). Authentication also occurs at various
times during the connection, by way of transferring the user name, initiator password (also called initiator
secret), and target password (also called target secret). RTX-IR 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.

R T X - I R U se r ’ s M a n ua l - 20 -

WiebeTech LLC

To use CHAP, you will need to turn on CHAP authentication (see section 6.5.3) and then set up a CHAP
account. 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.

The new CHAP account will appear on the main CHAP account screen:

6.6 Volume Config

The Volume Config menu provides the options you will use to set up a RAID on the RTX-IR. Click on
Volume Config to view the following menu options: Physical Disk, Volume Group, User Data Volume,
Cache Volume, and Logical Unit.

R T X - I R U se r ’ s M a n ua l - 21 -

WiebeTech LLC

The following diagram explains the architecture of RAID using RTX-IR and the relationship between
physical disks (PDs), volume groups (VGs), user data volumes (UDVs), and logical unit numbers (LUNs).

One VG (Volume Group) consists of a set of UDVs (User Data Volume) and owns one RAID level
attribute. Each VG can be divided into several UDVs. The UDVs from one VG share the same RAID
level, but may have different volume capacity. If multiple UDVs are created, they will mount on your
computer as separate partitions. Each UDV will be associated with one specific CV (Cache Volume) to
execute data transfers. Each CV could have different cache memory size as defined or configured by
user. LUN is a SCSI protocol that the computer uses to distinguish and access SCSI devices.

6.6.1 Physical Disk

Click the Physical Disk option to view and modify the status of the drives installed in the RTX-IR.

The following information is displayed:

• Checkboxes: Click the checkbox of any disk or disks, then click Free disks, Global spares, or
Dedicated spares to set the selected drive(s) to that status. Click the top checkbox to select all
drives.

• Slot: The slot number of the hard drive. 1 corresponds to the top bay of the RTX-IR. Click the
button below the slot number to display more information about that particular hard drive.

• WWN: The World Wide Name of the hard drive, an identification code unique to each hard drive.

• Size (GB): The logical capacity of the drive.

• VG (name): The Volume group the drive is assigned to, if any.

R T X - I R U se r ’ s M a n ua l - 22 -

WiebeTech LLC

• Status: Displays general operational status of the disk. Possible states are Good, Defect, and
Fail.

• 1: Displays the RAID status of the disk. Possible states are:

o RD – RAID Disk. The drive is part of a RAID that is currently online.
o FR – Free disk. The drive is available for use in a volume group, or to be marked as a

spare.

o DS – Dedicated spare. The drive is a dedicated spare of a specific volume group. This

option cannot be selected until at least one volume group has been created.

o GS – Global spare. The drive is a global spare of all VGs.
o RS – Reserve. The drive contains VG information but cannot be used. This generally

indicates that the drive is part of a RAID set that is missing components.

• 2: Displays RAID rebuild status of the disk. Possible states are “R” – Rebuild, or “M” – migration.

• Speed: The maximum speed of the drive. 1.5 Gbps indicates a SATA1 drive, 3.0 Gbps indicates

a SATA2 drive, and unknown indicates that the drive does not support either of the two levels.

Auto spindown: If auto spindown is enabled, after a set amount of time (30 seconds, 1 minute, 5 minutes,
or 30 minutes) of inactivity, RTX-IR will spin down the hard drives to save power. The drives will be spun
up again when the RTX-IR is accessed. Auto spindown is disabled by default. To enable auto spindown,
click the hyperlink “disabled.” On the following screen, select the desired auto spindown time from the
dropdown box:

Click the Confirm button.

6.6.2 Volume Group (VG)

The Volume Group screen displays information about all existing volume groups. To create a usable
RAID set, you will first need to create a new Volume Group. Click the Create button.

This brings up the VG creation screen. Enter a name for the new VG in the first field, then select your
desired RAID type from the dropdown box. WiebeTech recommends RAID5 for maximum performance,
capacity, and security. For more information on RAID, see Chapter 1: Introduction to RAID. Click Select
PD to select the drives that will be added to the VG. Note: Drives must be marked as Free Disks (FR)
before they can be added to a VG. To set drives to Free Disks, see section 6.6.1.

All available Free disks will be displayed. Check the drives that you wish to add to the VG, then click
Confirm.

R T X - I R U se r ’ s M a n ua l - 23 -

WiebeTech LLC

The selected PDs will now be displayed in the VG creation screen. Click next to proceed.

This brings you to a 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 VG.

The VG will now display on the main VG screen.

The VG screen displays the following information:

• No: The VG number. Click the button underneath the number of a VG to view more information.

• Name: The name of the VG. Click the button below a VG’s name to rename the VG.

• Total (GB): The total capacity of the VG. Note: This will depend on both the number and capacity

of the drives that are part of the VG, and the RAID type of the VG.

• Free (GB): The free capacity of the VG (not yet assigned to a UDV).

• #PD: The number of drives in the VG.

• #UDV: The number of UDVs that have been created as part of the VG.

• Status: The status of the VG. Possible states are Online and Fail.

• 1: Displays “DG” if the VG is degraded. This generally means a hard drive is missing or has

failed.

• 2: Displays “R” if the VG is rebuilding.

• 3: Displays “M” if the VG is under migration.

• RAID: The RAID level of the volume group. The button underneath the RAID setting indicates

“migrate,” but it is recommended that if you wish to change RAID types or add disks, you simply
recreate the VG using the new RAID type as this is generally faster.

6.6.3 User Data Volume (UDV)

The User Data Volume main screen displays any UDVs and allows you to create and delete UDVs.

R T X - I R U se r ’ s M a n ua l - 24 -

WiebeTech LLC

After a VG has been created, you can create associated UDVs. You must create at least one UDV to
access the drives of the RTX-IR with a computer. To begin this process, click Create. This brings up a
screen displaying the following:

• Name: Enter a name for the UDV

• VG name: Choose the VG that you wish to add the UDV too.

• CV no.: Cache Volume number – if you have created multiple caches, you can select between

them. Normally the default option is preferred.

• Capacity: Enter the capacity of the UDV. The default uses the maximum capacity of the
associated VG. If you wish to create multiple UDVs on the selected VG, you will need to reduce
the capacity below the maximum so that there is space left on the VG for additional UDVs.

• Stripe height (KB): Determines how the RTX-IR organizes the RAID. Normally the default option
is preferred.

• Block size: Determines the minimum file size of the UDV. 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 UDV over 2 TB in size, you must increase the
block size to 4096 to take advantage of the full capacity of the UDV. For more information,
see the Appendix, “Working with Volumes Greater than 2 TB”

• Read/Write: Allows selection of cache type. Normally the default option is preferred.

• Priority: Determines the priority that RTX-IR will give to RAIDing activities (rebuild, initialization)

versus priority given to file transfers. High priority will result in slower file transfers during
initialization, but provide for faster initialization.

After selecting your desired options, click Confirm. The new UDV will now display on the main UDV
screen:

The main UDV screen displays the following information:

• No.: The number of the UDV. Click the button below the number of a UDV to view more
information about that UDV.

• Name: The name of the UDV. Click the button below a UDV’s name to rename it.

• Size: The total capacity of the UDV. Click the button below the displayed size of a UDV to add

capacity to the UDV. Note: There must available space on the VG to extend the UDV.

• Status: The status of the UDV. Possible states are Online and Fail.

• 1: Displays the cache mode of the UDV. “WT” indicates that the cache is set to write through,

while “WB” indicates write back mode. Click the button below the cache mode to change the
cache mode.

• 2: Displays the priority of RAID functions for the UDV. Possible states are HI, MD (medium), and
LO. Click the button below a UDV’s priority to change the priority.

• 3: Displays the RAID activity of the UDV. “I” indicates that the UDV is initializing a RAID, “R”
indicates that the UDV is rebuilding a RAID, and “M” indicates that the UDV is under migration
between RAID types.

• R %: Displays progress of the activity indicated in column “3.” Note: Initializing a RAID5 may take
several hours.

• RAID: The RAID level of the UDV. This was chosen during the VG creation.

• #LUN: Number of LUNs that the UDV is using. 1 LUN must be attached before use with a

computer. See section 6.6.5 for more information on attaching a LUN.

• VG name: The name of the VG associated with the UDV.

• CV (MB): The cache volume of the UDV.

6.6.4 Cache Volume

The Cache volume screen allows the creation and management of multiple caches. By default, a global
cache using all of the cache memory is created and automatically assigned to all UDVs created.

The cache volume screen displays the following information:

• No.: The number of the cache. Global cache is always first. Click the button below to view more
information.

• Size: The size of the cache. By default, the global cache uses all available cache space. If you
wish to create additional caches, you must click on the button below the size of the global cache
and enter a number lower than the maximum value, then click Confirm. This frees up space to
create a new cache. Now click Create, enter the desired size of the new cache, and click
Confirm. The new cache will now be an option under “CV No.” when creating a new UDV.

• UDV name: The name of the UDV associated with the cache. Global is default for all UDVs.

6.6.5 Logical Unit

The Logical Unit is what your computer will use to access and manage SCSI devices. In order to access
a UDV, you will need to attach a Logical Unit Number (LUN) to that UDV. To attach a LUN, click the
Attach button:

The following options are available:

• UDV: Choose the UDV to which you wish to attach a LUN.

• Host: The Host field is filled with an asterisk by default, meaning that any host can access the

UDV. You may change the field if you wish to limit access to specific hosts.

• LUN: The LUN field allows you to select which LUN to attach to the UDV. The default option is
normally acceptable.

• Permission: Choose Read-write or Read-only for accessing the UDV.

Click Confirm after selecting your desired settings. The main Logical Unit Screen will now display the
LUN you have just created:

6.7 Enclosure Management

Enclosure management gives access to the following menu options: SES config, Hardware Monitor and
SMART.

6.7.1 SES Config

SCSI Enclosure Services, or SES, is a command set that is used to manage and sense the state of the
power supplies, cooling devices, displays, indicators, and individual drives of a SCSI device. The RTX-IR
is an SES compliant enclosure, however, in order to use manage RTX-IR using SES you must have the
appropriate software installed on your computer. An example is SMART Monitor, offered by Santools at

www.santools.com.

To enable SES on your RTX, you must have a UDV set up and a LUN attached. Once you have done
this, navigate to SES Config and simply click the Enable button, then click Confirm. The SES-enabled
LUN will show up on the main SES screen.

6.7.2 Hardware Monitor

R T X - I R U se r ’ s M a n ua l - 27 -

WiebeTech LLC

The Hardware Monitor displays information about the voltages and temperatures of the RTX-IR.

Auto shutdown feature: When this checkbox is enabled, the RTX-IR will automatically shut down if any of
the voltages or temperatures displayed stray outside of the minimum or maximum values. Auto shutdown
is enabled by default to protect the hardware of the RTX-IR.

6.7.3 S.M.A.R.T.

S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) is a diagnostic tool for hard drives that
gives advanced warning in some cases of hard drive failure. S.M.A.R.T. measures various attributes of a
hard drive at all times to detect if certain values have moved outside of a certain range. The S.M.A.R.T.
option allows you to view the S.M.A.R.T. status of all of your hard drives.

6.8 Maintenance

The maintenance screen gives access to the firmware and configuration functions: Upgrade, Info, Reset
to default, Config import & export, and Shutdown.

6.8.1 Upgrade

R T X - I R U se r ’ s M a n ua l - 28 -

WiebeTech LLC

The upgrade function allows you to upgrade the firmware of the RTX-IR. DO NOT USE THIS FUNCTION
WITHOUT SPECIFIC INSTRUCTION FROM WIEBETECH TECHNICAL SUPPORT. Doing so could
result in malfunction of your RTX-IR.

6.8.2 Info

Click on Info to display system information:

6.8.3 Reset to default

The Reset to Default option allows you to restore settings to the factory defaults. After clicking Reset to
Default, you will need to click Confirm to verify.

6.8.4 Config Import & Export

The config import & export function allows you to import or export a firmware config file. DO NOT USE
THIS FUNCTION WITHOUT SPECIFIC INSTRUCTION FROM WIEBETECH TECHNICAL SUPPORT.

6.8.5 Shutdown

The Shutdown feature allows you to shutdown or reboot the RTX-IR’s RAID controller and LCD controller.
Note: Choosing Shutdown will not shut down the physical components of the RTX-IR (fans, drives, power
supply). However, it will flush data from the cache to the physical drives, which is recommended before
physically shutting down using the power switch on the unit to prevent data corruption.

6.9 Quick Set-up of RAID

Follow these instructions to quickly create a RAID set using the GUI:

a. Click on Volume Config, then Volume Group.
b. Choose Create. Select the RAID level you would like to use (usually RAID 5). If there is an error

saying "Disk is not enough" you'll need to go to Physical Disk, select all of the disks you wish to include
in the Volume Group, and press the Free Disk button.
c. Click on Select PD. Select all the hard drives
you wish to put into the new RAID.* Click Next
to confirm your choice.
d. Next, go to User Data Volume (UDV) and
choose Create. Select the capacity you want
for this UDV. (See note at right.)
e. The rest of the details can be left at the
default setting. You’ll need to confirm several times.

NOTE: If the total capacity of your volume exceeds
2TB, it is likely you will encounter problems using that
volume on most current operating systems. If that is the
case, you will most likely wish to divide the capacity into
two or more volumes of less than 2TB each. Please
see the section labeled, "Working with volumes > 2TB."

R T X - I R U se r ’ s M a n ua l - 29 -

WiebeTech LLC

f. You should wind up back at the main UDV screen. The RAID will begin initializing, and progress

will be displayed in the R% column. Depending on the RAID type and size, the initialization could
take several hours. The R% number will disappear when the initialization has finished. Note: If
you selected RAID 0, you may not see a progress meter because it initializes almost instantaneously.
g. Select the check box next to the UDV you just created and then click Attach. If you created more than
one volume, you’ll need to repeat this step for each one.
h. Use the default settings on the next screen. You’ll need to confirm your selections.

* With the RTX400-IR, the number of drives contained in the RAID group can be as high as eight using
the four eSATA expansion ports on the rear of the unit. These ports allow you to connect another 4-bay
JBOD eSATA enclosure (e.g. RTX400-SJ), or multiple 1-bay eSATA drive enclosures and add those
additional drives to the RTX400-IR’s RAID. Note: These additional drives must be added at the time the
RAID is first created.

Chapter 7: Access the RTX using iSCSI Initiator
software

The process for using initiator software to access your RTX varies depending on the software used.
Read the documentation accompanying the software for details. However, the general steps are as
follows:

a. Launch the Initiator application
b. Type in the IP address of the Giga LAN connection on the RTX (determined in step 6). This will be a

different IP address than the one used to access the GUI.
c. The RTX volume will mount to your computer and appear as an internal SCSI drive. Newly-created
volumes will need to be formatted before they can be used. If you purchased the RTX with drives
preinstalled by WiebeTech, the volume(s) will already have been created and formatted appropriately for
your computer.

Below are additional instructions for two common iSCSI Initiator utilities:

Microsoft iSCSI Initiator for Windows

After you launch the initiator you'll see a window with several tabs, with the "General" tab opened by
default. Select the "Discovery" tab. Under Target Portals, click the "Add" button and enter the IP address
for the RTX’s Giga LAN port. Next, select the "Targets" tab. You should see a selection for the RTX-IR in
this Targets tab. Select that target and click "Log on." All the default settings are fine so just click OK. If
the log-on is successful you'll now be able to use the RTX-IR just like any other disk attached to your
computer.

Global SAN iSCSI Initiator for Mac OS

After you launch the initiator you'll see a window with several tabs, with the "Portals" tab opened by
default. Press the add button (“+”) and enter the IP address for the RTX’s Giga LAN port. Click OK.
Next, select the "Targets" tab. You should see a selection for the RTX-IR in this Targets tab. Select that
target and click "Log on." All the default settings are fine so just click “OK” or “Connect”. If the log-on is
successful you'll now be able to use the RTX-IR just like any other disk attached to your computer.

R T X - I R U se r ’ s M a n ua l - 31 -

WiebeTech LLC

Chapter 8: Formatting new volume(s)

If you did not purchase the RTX with preconfigured drives, you will need to format the new volume(s)
before using them. This is typically done using tools built in to your computer’s operating system. (For
example, Disk Utility for Mac OS X or Disk Management for Windows.) Consult your computer’s
operating manual for details.

Usage with Macintosh computers

Mounting and Ejecting Volumes

When you connect the unit to the Mac for the first time and turn on the power,
you’ll probably see a message saying that the disk is unreadable. This is
because you must format the volume before using it. The easiest way to do
this is to use Mac OS X’s Disk Utility. If you plan to use the unit on both Macs
and PCs, select “MS DOS File System” as the format type. If you only plan to
use the unit on Macs, then select “Mac OS Extended”. After the volume is
formatted, an icon representing the drive volume will appear (“mount”) on the
desktop. You can now use the volume just like an internal hard drive.

Eject the volume before powering down the unit by dragging the volume’s icon
to the trash bin, or by selecting the volume then pressing Command-E. Shutting down the unit without
first ejecting the volume can result in data loss.

NOTE: When formatting a volume larger than 2TB in
Windows Vista, you may be prompted to select either
MBR or GPT for initialization. MBR will truncate the
volumes to 2TB each, creating multiple partitions if
necessary. GPT will allow volumes over 2TB, but is not
compatible with all previous versions of Windows.

Usage with Windows computers

Formatting Volumes

Before you can use your RTX-IR, you must first format the drives into a volume. Use Disk Management,
which you can find by right-clicking on My Computer then selecting Manage. Select NTFS for the format
type.

After the volume is formatted, an icon representing the drive volume will appear in My Computer. You
can now use the volume just like an internal hard drive.

Ejecting Volumes

Unlike external storage devices that connect via FireWire or USB, SCSI devices cannot usually be
ejected. It is possible to disable the device using Device Manager. Whether or not you choose to disable
the device in this way, always make sure the drives are not being accessed before shutting off the RTX­IR. If the unit is turned off in the middle of a data input/output process, data loss may result.

Appendix C: Working with Volumes over 2TB in size

Although the RTX can create data volumes larger than 2TB, operating systems cannot usually access
such volumes. This is because most systems support only 32-bit LBA (Logical Block Addressing).

Newer operating systems (Windows Server 2003, Vista, Mac OS 10.5.x) should be able to use 2TB+
volumes without difficulty. You will simply need to do one of the following two things while creating the
UDV (User Data Volume):

• Change the LBA to 64-bit

• Increase the block size to 4096

Windows

Neither of the options above will work for Windows versions before Server 2003. You will need to make
more than one UDV, each less than 2000GB in size. Each UDV also needs a different LUN.

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.

Appendix D: Warnings and Notices

• 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.

• The 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. You must reformat your drives afterwards.

• Before starting any type of hardware installation, please 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-ventilated area and in such a way that
sufficient airflow is maintained across the controller chips.

• Static electricity can damage electronic components such as the exposed circuitry on hard drives.
When swapping hard drives in the RTX, take precautions to guard against such damage:

o Work in a static-free environment
o Wear a grounded anti-static wrist strap
o Store uninstalled components in anti-static protective bags
o Handle the drives by their edges and avoid touching the exposed circuitry

Appendix E: Frequently Asked Questions (FAQ)

Q. I created one volume, but my computer sees two of them. Why?
A. There may be two LUNs assigned to that volume. To check this, use the GUI. Navigate to Volume

Config and then Logical Unit. If there are two LUNs for the same volume, click the checkbox for one of

them and click on “detach.” Note: You may still see two volumes until you restart your computer.

Q: I've hooked up the LAN 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 LAN GUI after the RTX has already started up and initialized, or if
you previously configured the 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. The 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-IR using the IP address under the iSCSI configuration menu nothing
happens.
A. Sometimes when you first set up the RTX-IR you'll need to reattach the LUN (Logical Unit Number) 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-

IR. 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 LUN to a UDV 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 UDV. 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.wiebetech.local,
if I put that name into the host field when attaching a LUN 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 LUNs to one UDV.

Q. If I connect one computer to the 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?
A. One computer at a time can directly access the RTX, but files on the RTX can be shared from that
computer to other computers. In such a scenario, the computer attached to the RTX acts as a server.
Only the server computer requires an iSCSI initiator. The other computers do not need special software.
The difference between iSCSI and NAS (Network Attached Storage) 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 the RTX. How can I prevent
this?
A. To prevent difficulties such as this, follow the shutdown procedures on page 11. It is suggested that
you disable automatic sleep on your computer so it does not go into sleep mode without preparing the
RTX for disconnection.
