host. Avoid all dramatic movement, tapping on the
unit, and vibration.

• 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, the RTX enclosure should be
operated in a well-ventilated area.

• Remove the drives before transporting the RTX
enclosure to prevent damage to the drive interfaces.

RAID

• Use only hard drives that are in perfect condition.
Avoid using drives that have ever developed bad
sectors during previous use. This could lead to
possible device failure or loss of data.

• The RTX enclosure supports SATA hard drives
of various specications and different capacities.

However, we recommend using drives of the same
brand and type across all bays 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.

5 Conguring Drive Redundancy

If a drive in a RAID group fails, the RAID group’s status
becomes degraded. In order to maintain RAID integrity, you
should plan ahead and use one of these methods to ensure
that should a drive fail, your data will not remain at increased

risk for long. Use the method below that best ts your needs.

5.1 Create a Hot Spare Pool

A faulted drive is automatically replaced if a suitable disk is

available in the Hot Spare Pool. You set up a Hot Spare Pool

with drives reserved until a RAID group member fails; they
are not available when creating a RAID group.

a. Use the ATTO CongTool to log in to the

ThunderStream SC 3808E properties as detailed
in Section 3.2.3 , Steps A through E. and click on the
RAID tab.

If you want to change other parameters from the default
values, click Next and select the desired property.

i. After you selected Next in the step above, customize

the following properties: SpeedRead, Auto-Rebuild,
and Rebuild Priority. Refer to Section 6 for specic

5.2 Enable Auto-Rebuild
When Auto-Rebuild is enabled, the RTX enclosure will

automatically use any suitable unallocated drive it nds

as a replacement for a faulted drive. Suitable drives must
be large enough to replace the degraded drive and cannot

contain any RAID group information. If a Hot Spare Pool

exists, the RTX enclosure will default to using an available
Hot Spare drive from the pool before searching for an
unallocated drive.

Refer to Section 6 for instructions on how to enable Auto­Rebuild.

6 Change RAID Group Properties

Some of these properties can

only be specied during the

creation of the RAID group while
others may be changed at any
time during the life of the RAID
group.

a. Use the ATTO CongTool

to log in to the

ThunderStream SC
3808E properties as detailed

in Section 3.2.3 , Steps A
through E.

b. Right click on the RAID Group in the Groups panel

listing and click on Properties.

Auto-Rebuild
Controls the replacement of a faulted drive with any
available unallocated drive. When you click on the
Auto-Rebuild check box and the Accept button, Auto­Rebuild is enabled. If a drive becomes faulted, the SAS/
SATA RAID storage controller replaces the drive with an
unallocated drive.

Rebuild Priority
Species the ratio of rebuild I/O activity to host I/O

activity.

Setting Description

Same

(default)

Low Host I/O is given higher priority

High Rebuild I/O is given higher priority

Both rebuild and host I/O’s are treated equally

Prefetch
Species the number of stripes that are read when

SpeedRead is enabled or adaptive. This property can
only be changed after the RAID group is created. To
access this property, select the RAID group and view its
properties.

d. Click Accept.

7.1 Rebuilding the RAID Group
The recovery methods listed in this subsection can be used
to recover from failures that are non-destructive to your
data. Although the RAID group remains intact, its data is at
an increased risk of becoming corrupted and the failed hard
drive should be replaced as soon as possible. The data will

only be corrupted if the RAID group fails and goes ofine. If
enough drives fail, the RAID group will be forced ofine. See

Section 2.1 for information on how many drives can fail in
a given RAID mode.

7.1.1 Automatic Replacement
If a Hot Spare pool has been created, the RTX enclosure
will automatically rebuild data to a hard drive that is
inside the pool. If no drive is available in the Hot Spare
pool but Auto-Rebuild is enabled, the RTX enclosure will
use any available hard drive in the RTX enclosure that is
not currently part of the RAID group to rebuild the RAID
group.

If neither of these options is enabled, you will have to
manually replace the failed drive.

See Section 5.1 for information on how to create a Hot
Spare pool or Section 6 for information on how to enable
Auto-Rebuild.

c. A RAID group members tab displays in the bottom

panel. Select an unallocated drive from the drive
inventory in the above panel and drag it over the
degraded RAID drive in the members tab.

If the selected drive is appropriate, the faulted drive is
replaced and the RAID will rebuild.

7.1.3 Recovery from Replacement of a Wrong Drive
When a drive fails but the wrong drive is replaced,

the RAID group will go ofine instead of being rebuilt.

Replace the wrongly-replaced drive with the original,
then identify and replace the real failed hard drive. A
rebuild should begin automatically. But if it does not,
right click on the ofine RAID group in the Groups panel
and select the option Rebuild Group.

7.2 Data Recovery
Basic Recovery Mode allows you to back up your data from

an ofine or failed RAID group and restore it to a new RAID

Group. This method is not guaranteed to recover data

however. Any time a RAID group goes ofine it means that

the integrity of the data has been compromised and some
or all of the data may have been corrupted. You should run

le system repair tools to validate all of the data on the RAID

after recovery before attempting to use it again.

a. Use the ATTO CongTool to log in to the

ThunderStream SC 3808E properties as detailed in
Section 3.2.3 , Steps A through E.

b. Right click on the ofine RAID Group and select the

option Basic Recovery.

7.1.2 Manual Replacement
a. Use the ATTO CongTool to log in to the

ThunderStream SC 3808E properties as detailed
in Section 3.2.3 , Steps A through E.

b. Right click on the degraded RAID group in the

Groups panel and select Rebuild Group.

The RAID Group status will change from Ofine to Recovery

(Basic). Now you may use a host application to read the
remaining intact data off of the drives and back it up to
another location. The RAID group will remain in recovery
mode and there is no way to put this RAID group back
online. Once the data is backed up, use only good drives
to create a new RAID group and then restore the data to it.

8 RAID Notications

RAID event notications can be congured using the
Notications tab in the host system properties panel within
the ATTO CongTool:

a. From the Device Listing panel on the left, expand the list

and select the computer that your RTX is plugged into. If
the RTX enclosure is plugged into the computer you are
currently using, select localhost.

Audible
When triggered, a buzzer will continuously sound through
the host computer’s speakers until stopped by the user.

To silence the alarm, right click on the Notication Agent’s

red “A” icon in the Desktop task bar (Windows) or Menu
Bar (Mac OS) and select Mute audible alert from the
pop-up menu. You may have to click on the Show Hidden

Icons arrow on the task bar to nd the correct icon.

b. Select the Notications tab that appears on the right.

RAID events are divided into 3 categories:

• Critical events indicate a serious problem has
occurred and the administrator of the RAID group
should perform corrective action.

• Warning events are less serious but still warrant

notication.

• Information alerts provide additional useful
information about warnings or critical events.

Each type of notication can be congured to notify only on
specic levels of RAID events. There are four options available:

• Critical: Only Critical events are reported.

• Warning: Only Warning and Critical events are

reported.

• All: All RAID events (Information, Warning, Critical)
are reported.

Visual
Visual alerts are pop-up message boxes that appear on the

host computer’s screen when a RAID event occurs.

System Log
The events you specify here will be recorded directly to the
system event log.

8.2 Conguring E-Mail Notications

To congure e-mail notications, navigate to the

Notications tab using the instructions found at the
beginning of Section 8 , and then enter each of the following
settings in the Email section:

• None: No RAID events are reported and RAID

notication is disabled.

8.1 Conguring Visual, Audible, and System Log Alerts

• Server Address: The address to your provider’s

SMTP email server

• Sender Address: This is the text that will appear

in the “From” eld of the sent email. This typically

contains the email address that the email is being

The Basic Alerts section on the Notications tab lets you
congure which levels of RAID events will trigger Audible
and Visual alerts and which ones will be recorded in the

• Port: The port number of the email server.

• Notication Addresses: Input the email addresses

that the notication emails will be sent into these
three text elds. Each eld may contain more than

one address, each separated by a comma. Each text

eld can be congured to receive a specic level of

RAID event using the drop-down boxes to the right.

Email notications are sent every 15 minutes. If a critical
RAID event is detected, the ATTO CongTool will wait 10

seconds to collect data on supporting RAID events that
may be useful in identifying the cause, and then send the

notication.

8.3 Retrieving System Logs

Open the ATTO CongTool

and choose the Help → Run
Diagnostics… Then choose a

place to save the log le. It may take

several moments for the process
to complete. The log includes the
system event log for each enclosure and storage controller
with an ATTO chipset (such as the RTX enclosure) as well

as logs for SNMP functionality and the ATTO CongTool

background process itself.

9 Usage with Mac and Windows Operating

Systems

9.1 Usage with Mac OS X

9.1.1 Formatting the RAID Group
To format, use Disk Utility (pictured below), which can be
found in the Applications folder.

a. Click on the drive in the window to the left.

9.1.2 Mounting and Unmounting Volumes

If the RAID group for the RTX enclosure is already
formatted, an icon representing the RAID group’s volume
will appear (mount) on the desktop. You can begin using
the volume right away. If the RAID group is unformatted,
a message will appear on the desktop saying that the
volume is unreadable. Use OS X’s Disk Utility
to easily format the drive (see section above).

Unmount the volume before powering down
the unit by dragging the volume’s icon to
the Trash, or by selecting the volume then
pressing Command-E. Disconnecting the

unit without rst unmounting the volume

can result in data loss.

9.2 Usage with Windows Operating Systems

9.2.1 Formatting the RAID Group

When you rst mount the RAID group to a Windows

operating system, a pop-up window will ask you if you
would like to format it. Click Format Disk and skip
to Step E. If the prompt does not pop up, use the Disk
Management utility by following these steps:

Windows will indicate when it is safe to disconnect the

RTX enclosure. Disconnecting the enclosure without rst

ejecting its RAID group volume can result in data loss.

10 RAID Is Not A Backup

Because your RTX enclosure 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

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 data storage
manufacturers).

Plan accordingly and backup data to minimize downtime!
