1.0 ATTO Conﬁguration Tool Overview

About the Configuration Tool

The ATTO Conﬁguration Tool is a utility program that displays information about installed controllers, drivers and drives, and provides a mechanism to conﬁgure installed controllers.

This program executes under:

• Mac OS X 10.4 or later

• Windows Vista /XP/Server 2003/2000

• Linux 2.6 kernel, x86 and x64

Note: Java version 1.5 or later must be installed.

The ATTO Configuration Tool displays:

• The name of the Sonnet RAID controller ( Rxxx adapter)

• Information about the drivers controlling the Sonnet RAID controller, including version information for both the currently executing driver and the ﬂash image

• Information about drives attached to the Sonnet RAID controller

You may use the Configuration Tool to:

• Manage RAID groups

• Conﬁgure RAID Event notiﬁcations

• Modify the RAID controller’s NVRAM settings

• Revert to default factory settings

• Update the RAID controller’s ﬂash image

• Update ﬁrmware on huge disk arrays

The factory settings on your Sonnet RAID controller should provide excellent performance for a wide range of applications. However, some applications may beneﬁt from modiﬁcation of the controller’s NVRAM settings that tune the controller for a speciﬁc performance range.

1.2 RAID Settings

Support Note: In Fusion RAID systems shipped from

Sonnet with hard drives installed, the drives are formatted Mac OS Extended (Journaled), and configured as a single RAID 5 RAID group. If you need to change the configuration, use the ATTO Configuration Tool and the operating system software tools to reformat and reconfigure the drives. See page xii for Quick Format instructions for Mac OS and Windows users.

The ATTO Conﬁguration Tool provides the capability to conﬁgure disk storage into RAID groups or Hot Spare drives.

Note: Even an individual JBOD disk is considered to be a RAID group.

Use the ATTO Conﬁguration Tool to set up RAID groups on your Sonnet RAID controller in one of the following RAID levels:

• JBOD

• RAID Level 0

• RAID Level 1

• RAID Level 4

• RAID Level 5

• RAID Level 6

• RAID Level 10

• DVRAID

Support Note: DVR AID is a customized, protected

RAID 4 configuration. It is optimized for increased digital video playback performance when compared to that obtained from a RAID 5 configuration. DVRAID’s write per formance is decreased in order to accomplish this optimization.

DVRAID RAID groups may be set up automatically by the ATTO Conﬁguration Tool. All other RAID conﬁgurations require customized input.

Each RAID group may be divided into one or more partitions; each partition appears to the host operating system as a virtual disk.

Windows Support Note: In order to create RAID

volumes larger than 2TB under Windows, you must do one of the following: Select the 4KB sector size when creating a custom RAID group (not DVRAID). -OR- Use the software configuration tools included with the Fusion storage to create volumes up to 2TB, concatenate (link together in a virtual chain) the volumes, and then format as NTFS. -OR- Use GPT formatting. Note that drives and volumes with GPT formatting are not visible to any version of Windows XP Professional, nor to the 32-bit version of Windows Server 2003 SP1.

You may use the command line interface pane from the

RAID

CLI tab in the ATTO Conﬁguration Tool to set up or modify

various parameters (Refer to Appendix A).

However, the menubased procedures listed in this chapter are the preferred procedures for setting up RAID configurations for the Sonnet RAID controller.

Preliminary Configuration Steps

1. Launch the ATTO Conﬁguration Tool application.

2. The Conﬁguration Tool main screen appears. See Figure 10 on

page 12 for an overview of the screen. In the Device Listing pane on the left side of the window, click ExpressSAS Rxxx under

3. Click the RAID tab; attached drives are displayed in the top pane, while RAID groups and Hot Spares are displayed in the bottom pane.

DVRAID RAID Group Setup

The DVRAID wizard automatically sets up a DVRAID RAID group using all available drives attached to the Sonnet RAID controller. If you do not want all available drives set up in a DVRAID RAID group, either remove the drives from the drive enclosure, or select Custom RAID setup.

WARNING: After selecting the DVRAID, R AID 4, RAID 5,

or RAID 6 option, configuration of a set of eight 1TB drives can take up to 4 hours (or up to 2 hours with 500GB drives).

1. After completing Preliminary Conﬁguration Steps on this page, select RAID Management > Create Group > DVRAID Setup from the application menu.

2. A dialog window will pop up, asking whether you want to perform an Express Setup Operation of DVRAID; click Yes. The ATTO Conﬁguration Tool automatically uses all unassigned drives to create a DVRAID RAID group. While the RAID group is being created, a message box displays and the panes display the RAID groups.

The RAID group must still be formatted by your computer’s operating system software before it becomes available for use.

For Mac users, use Disk Utility; for Windows users, use Disk Management. For more information on drive formatting, see Mac OS Drive Formatting or Windows Drive Formatting on page 11.

4. After formatting, RAID groups may be used during the setup operation, but performance is limited until setup is complete.

Hot Spares Usage

If a drive in a RAID group becomes degraded or faulted, your RAID group will lose some redundancy until a new member (drive) is rebuilt into it. You can automate this procedure by designating one or more drives as Hot Spares. You may set up a pool of Hot Spare drives of different sizes appropriate for your RAID groups.

Support Note: Hard drives in the Hot Spare pool

should be of appropriate capacity to the RAID group so that smaller drives are not replaced by much larger Hot Spare drives.

If the Sonnet RAID controller detects a faulted drive in a RAID group with a designated Hot Spare:

• The controller searches the Hot Spare pool for the smallest drive of sufﬁcient capacity to substitute for the faulted drive.

• The faulted drive is replaced with the drive from the Hot Spare pool.

• The Sonnet RAID controller begins an automatic rebuild of the RAID groups.

Select RAID Management > New Hot Spare (or Delete Hot Spare) from the application menu, and then follow the instructions on the screen.

RAID Group Capacity Expansion

Select RAID Management > Expand Capacity from the application menu, and then follow the instructions on the screen. Depending on the RAID conﬁguration, you may need to add more than one drive at a time.

WARNING: Adding drives to an existing RAID group may

adversely impact performance. You cannot reverse this

operation unless you delete the RAID group.

RAID Level Migration

Changing a RAID group from one RAID level to another is called migration. The following migration levels are supported:

• JBOD to RAID Level 0

• JBOD to RAID Level 1

• RAID Level 0 to RAID Level 10

• RAID Level 1 to RAID 10

• N-way mirroring: add additional redundancy to RAID Level 1

Select RAID Management > Migrate RAID Level from the application menu, and then follow the instructions on the screen.

RAID Group Deletion

You may delete a group using the ATTO Conﬁguration Tool. Select RAID Management > Delete Group from the application menu, and then follow the instructions on the screen.

RAID Group Management Overview

The ATTO Conﬁguration Tool interface may be used to replace a failed drive, add capacity to a RAID group, or change a RAID group’s current RAID level conﬁguration to a new one.

WARNING: Data can be compromised or lost when

deleting storage or rearranging storage configurations.

The ATTO Conﬁguration Tool interface guides you step by step through many procedures which allow you to modify your storage and RAID conﬁgurations. Read all notes and cautions carefully as you go to ensure the best performance and use of your storage. Many of these procedures are only available with drives that are not currently part of a RAID group, are not designated as a Hot Spare, or were ofﬂine when you initially set up RAID conﬁgurations.

Support Note: An unallocated drive or unallocated

storage is storage which is not part of a RAID group, not designated as a Hot Spare or was offline when you initially set up a RAID configuration using the ATTO Configuration Tool interface.

WARNING: Data can be compromised or lost when

deleting storage or rearranging storage configurations.

RAID Group Rebuilding

If a RAID group becomes compromised, you must rebuild it. Select RAID Management > Rebuild Group from the application menu, and then follow the instructions on the screen.

Support Note: A RAID group rebuild may take up to

eight hours to complete, depending on the operating

system, drive capacities, and RAID configuration.

You may pause the RAID group rebuild process by selecting the RAID group in the lower pane, and then selecting RAID Management > Pause Rebuild from the application menu. To restart the rebuild, select the RAID group in the bottom pane, and then select RAID Management > Resume Rebuild from the application menu.

1.3 Drive and RAID Group Monitoring

S.M.A.R.T. Data Monitoring

Self-Monitoring, Analysis and Reporting Technology, or S.M.A.R.T., is a monitoring system for SATA drives to detect and report on various indicators of drive health. The S.M.A.R.T. (SelfMonitoring, Analysis and Reporting Technology) monitoring feature monitors and reports the status of SATA drive health using certain parameters recorded by the drives. Notiﬁcation is sent when the values exceed certain pre-determined values.

Use the ATTO Conﬁguration Tool to view the ﬁles that record changes to an individual drive’s S.M.A.R.T. parameters. The ﬁles are permanent and can be viewed independently whether you have enabled monitoring or not.

S.M.A.R.T. Monitoring Enabling and Disabling

You may enable or disable the monitoring feature at any time. Monitoring is disabled by default; if you want to use the feature, you must enable it.

1. Launch the ATTO Conﬁguration Tool application.

2. Expand the device tree to show the ExpressSAS Rxxx, and then click the RAID tab.

3. Select RAID Management > Monitor S.M.A.R.T. from the application menu to enable (indicated with a check mark) or disable monitoring.

S.M.A.R.T. Status Checking

The ATTO Conﬁguration Tool interface displays the latest S.M.A.R.T. status record for a selected drive. All attributes reported by the drive are listed with each attribute’s Current and Raw value; the threshold value is the value at which notiﬁcation of a problem is generated by the software.

If there has been a change from a previous S.M.A.R.T. status record, an arrow indicates the change direction, either higher or lower. See

Figure 18 on page 20.

Threshold, Worst,

The S.M.A.R.T. status display also contains information such as the date and time the S.M.A.R.T. status was recorded, the total number of records for this drive, and the current monitoring status (enabled or disabled).

You may move to previous or subsequent records, query the drive or refresh the view using controls on the interface. Control-click (or right-click) a single drive in the Attached Drives panel, and select S.M.A.R.T. Status from the sub-menu to view the record.

• Use the left arrow or right arrow control to move between S.M.A.R.T. status records.

• Use the Refresh button to query the drive for the latest values. If any values are different from the most recent record, a new record is created and displayed.

S.M.A.R.T. Attribute Filtering

Each of the S.M.A.R.T. status attributes is assigned one or more classiﬁcation types:

• performance

• error rate

• event count

• critical

The S.M.A.R.T. Status dialog box can be ﬁltered to display any combination of these types. The default view is to display all types.

1. Open the S.M.A.R.T. Status box, and then control-click (or

2. Each classiﬁcation type that is visible has a check mark.

right-click) in the table area where the attribute values are displayed.

Select any classiﬁcation type to change the check mark.

S.M.A.R.T. Notifications

When S.M.A.R.T. monitoring is enabled, status is collected from each SATA drive at 60 minute intervals. If the data is different than the previous status, a S.M.A.R.T. status record is added to the S.M.A.R.T. status ﬁle for that drive. A notiﬁcation of the S.M.A.R.T. status difference is generated based upon the current settings in the Notiﬁcations panel. Refer to Notiﬁcations on page 21.

The notiﬁcation level of S.M.A.R.T. status is determined as follows:

INFO: None of the status values was below the threshold value.

•

WARNING: One or more of the status values was below a

• threshold value but none was classiﬁed as critical.

• CRITICAL: One or more of the status values was below a threshold value and one was classiﬁed critical.

1.4 Notiﬁcations

The ATTO Conﬁguration Tool provides a way to issue notiﬁcations via audible or visual alerts when a RAID event occurs.

RAID events are divided into three categories:

• Critical events are ones in which a serious problem has occurred and the administrator of the RAID group should perform corrective action.

• Warning events are less serious but still warrant recording and notiﬁcation at some level.

• Information alerts provide supportive information about warnings or critical events.

Drop-down boxes on the Notiﬁcations pane allow you to choose the type of event which prompts an alert. See Figure 19 on page 22.

• Critical: only Critical events are reported

• Warning: all Warnings and Critical events are reported

• All: all Critical, Warning and Information events are reported

Logging

Logging notiﬁcation records the type of event as text in a log ﬁle you specify. Select the location, name and size of the ﬁle.

• An integer value is added to the log name. When the log ﬁle reaches its size limitation, a new ﬁle is generated with a sequential integer value added to the log name. When the second log ﬁle reaches its size limitation, logging overwrites the ﬁrst log ﬁle. The two log ﬁles are automatically rotated.

E-Mail Alert

E-mail notiﬁcation sends a message to the designated E-mail addresses when the event level from the drop down box is reached.

• You may specify several notiﬁcation addresses on each line in the E-mail section of the Notiﬁcations pane, each separated by commas, for any event level.

• You must complete the IP address or name of the server and sender.

• You may specify a user name and password for the mail server if one is required.

• None: no event is reported. The None level is useful in E-mail notiﬁcation because you can set up E-mail addresses to which alerts might be sent at some future time.

You may choose any combination of notiﬁcations on the Notiﬁcation pane as needed. The notiﬁcations are speciﬁed at the host system level and apply to all Sonnet RAID controllers installed in the host system.

Basic Alerts

You can select an audible alert, a visual alert, or both for a particular category of events. Select a notiﬁcation level using the drop-down box next to the Audible and Visual labels on the Notiﬁcations screen.

Audible alert uses the computer’s speaker to sound an alarm for 5 seconds.

Visual alert uses a system modal pop-up to display a message. You must close the pop-up using the pop-up’s button.

Support Note: The visual alert option is not available on

systems running Linux, nor on systems running Mac OS X

and using version 3.1.0 software.

• A critical event E-mail notiﬁcation is sent after a 10-second delay to allow several related events to be reported in the same message. All other notiﬁcation E-mails are sent at 15-minute intervals.

1.5 Diagnose and Replace a Faulted Drive

A drive error may occur that will cause a RAID group to become degraded. This section will help you to identify and replace the bad drive.

When an error occurs that requires a drive to be replaced, the ATTO Conﬁguration Tool will issue visual, audible, and E-mail notiﬁcations (only when conﬁgured to do so).

Support Note: The Sonnet RAID controller is unable to

automatically turn on fault lights in the drive enclosure, so the ATTO Configuration Tool must be used to activate the LED for the faulted drive.

Faulted Drive Identification

After a drive failure notiﬁcation has appeared,

1. Launch the ATTO Conﬁguration Tool application.

2. Expand the device tree to show the ExpressSAS Rxxx, and then click the RAID tab. Drive status for all drives connected to the Sonnet RAID controller will be displayed. The faulted or degraded drive will have a red LED icon next to it.

Support Note: If you have configured your setup to

include a Hot Spare drive, the ATTO Configuration Tool will automatically start rebuilding the RAID group using the Hot Spare drive.

Faulted Drive Replacement

Once you have identiﬁed the faulted drive, you must replace it and rebuild the affected RAID group.

1. Swap out the faulted drive.

2. Launch the ATTO Conﬁguration Tool application.

3. Expand the device tree to show the ExpressSAS Rxxx, and then click to highlight the degraded RAID group.

4. Select RAID Management > Rebuild from the application menu; a tab for the RAID group will open, and you will be prompted to drag a free drive on top of the one being replaced. See

5. After starting the rebuild, you may use the RAID group, but its performance will be reduced until the rebuild is complete.

Support Note: A RAID group rebuild may take up to

eight hours to complete, depending on the operating

system, drive capacities, and RAID configuration.

Figure 19 on page 24.

3. Click on the faulted or degraded drive you want to identify in the Attached Drives list.

5. Double-click the faulted or degraded drive in the top pane to display detailed information, and note the index number for the drive. Close the detailed drive information window.

6. Click the RAID CLI tab, and then type “Blockdevidentify x”, where

x is the index number. Look at the Fusion enclosure;

the drive activity LED for the speciﬁc drive will be lit.

Note: Type “Blockdevidstop” to turn off the LED.

You may see an error message informing you about an unexpected event or incorrect information discovered by the application. Using the help text presented with the error message, correct the issue before proceeding.

Warnings and error messages are displayed in the

Status pane.

Messages from NVRAM Tab Actions

• An error occurred loading NVRAM data.

The ﬁrst time a channel is highlighted, the Conﬁguration Tool attempts to read NVRAM from the card. This message usually indicates that the Conﬁguration Tool could not communicate with the driver, probably because the application does not support the driver version in use.

• Warning: NVRAM could not be read, defaults returned.

NVRAM is corrupt and the driver returns to the default conﬁguration. The defaults are presented via the graphical user interface. These defaults may be modiﬁed but the defaults or modiﬁcations must be committed (saved) in order to correct NVRAM.

• This HBA is not compatible with the selected flash file. ATTO ﬂash ﬁles are created based on the type of card ﬂashed. Only certain ATTO ﬂash ﬁles are compatible with the Sonnet RAID controller. When a ﬂash ﬁle is selected, it is inspected for compatibility.

•

A valid file was not selected. You clicked the Cancel button on the ﬂash ﬁle selection dialog.

• An error occurred reading from the flash file, the file may be corrupt. You selected a compatible ﬂash ﬁle but the contents are corrupt.

• An error occurred updating the flash. You tried to ﬂash a card when the ﬁrmware was not able to accept a ﬂash.

•

The card has been prepared for firmware updating, but the machine must be rebooted for the changes to take effect. You need to repeat this process after rebooting to actually update the firmware.

Some ﬁrmware upgrades need to prepare the existing ﬁrmware in order to successfully update the controller. Rebooting allows the changes made during the preparation process to take effect, and the same ﬁle should be ﬂashed again.

2.0 Windows Only - ATTO Disk Benchmark

The ATTO Utilities for Windows are installed from the CD that was included with your Sonnet RAID controller. Only one utility, Disk Benchmark, may be used with your Sonnet RAID storage system.

Disk Benchmark measures peak and sustained throughput for disk reads and writes. See Figure 21 on page 28. You may locate the Disk Benchmark application in the ATTO HBA Utilities folder within your system’s Applications folder.

1. Launch the application.

2. Select the drive letter for the disk to benchmark.

3. Select the transfer sizes to test.

4. Select the I/O option.

5. Click the Start button.

6. Wait for benchmark to run through the desired transfer sizes.

7. The Test Results Display at the bottom of the window is updated as the test progresses. The y-axis of the graph represents the transfer sizes in the selected range. The x-axis represents the transfer speeds in MB/sec. I/O speeds in KB/sec. for each transfer size are displayed textually to the right of the graph.

Support Note: Additional information on using Disk

Benchmark is available by accessing the Help menu in the

application.

Benchmark Fields

The benchmark ﬁelds include:

Drive: Select the logical drive to benchmark. A test can be

• performed on any system drive.

• Transfer Size: Select the range of transfer sizes used for reading and writing data to the test drive. Transfer speeds are displayed for each size in the range. If the ﬁrst size is greater than the second size, the test is not performed for any transfer size.

•

Total Length: Select the total size of the data ﬁle to be created on the test drive. This ﬁle is deleted when testing completes.

• Direct I/O: If this option is checked, ﬁle I/O on the test drive is performed with no system buffering or caching. Combine this option with performance

2.1 ATTO Disk Benchmark Troubleshooting

The following suggestions may help if you encounter problems with Disk Benchmark.

• Use Windows Device Manager to check and verify that all drives are visible to the operating system.

• If drives are not listed, check the connections between the drive enclosure and the RAID controller card, and verify that all drives are fully seated in their bays.

• Make sure that the enclosure is powered up and has completed its self check before booting your computer.

• Reboot your system any time you make changes to a RAID group (after the RAID group has been rebuilt).

• As a last resort, you may use the ATTO Boot Conﬁguration Utility to low level format a troublesome device. However, this erases all information on the disk.

• Have you partitioned your drive, and then activated that partition?

• Did you format the drives for use with your operating system?

If problems persist, contact Sonnet customer service.

Help output and command

Appendix B - Quick Drive Format Instructions

If your Sonnet Fusion RAID storage system shipped with pre-installed hard disk drives, the following information will assist you to reformat the drives per your needs.

In Fusion RAID systems shipped from Sonnet with hard disk drives installed, the drives are formatted Mac OS Extended (Journaled), and conﬁgured as a single RAID 5 RAID group. If you need to change the conﬁguration, use the ATTO Conﬁguration Tool and the operating system software tools to reformat and reconﬁgure the drives.

Mac OS Users’ Instructions

1. Follow all the steps in the included documentation to install the software and the Sonnet RAID controller, and to set up and connect the Fusion RAID drive enclosure.

2. Start your computer, and then turn on the Fusion drive enclosure; the RAID volume should appear on the desktop.

3. Drag the volume to the trash (changes to an eject icon) to eject it.

4. Launch the ATTO Conﬁguration Tool.

5. Select RAID Management > Delete Group from the application menu.

14. Depending on how you conﬁgured the RAID groups, the volumes may already be mounted and present on the desktop. If you created a DVRAID, RAID Level 4, or RAID Level 5 group, conﬁguration will take much longer. You may check on the process by double-clicking the RAID group name in the lower pane of the

ATTO Conﬁguration Tool window.

Windows Users’ Instructions

1. Follow all the steps in the included documentation to install the software and the Sonnet RAID controller, and to set up and connect the Fusion RAID enclosure.

2. Start your computer, and then turn on the Fusion drive enclosure.

3. Launch the ATTO Conﬁguration Tool.

4. Expand the device tree in the Device Listing section on the left side of the window until ExpressSAS Rxxx is displayed, and then click ExpressSAS Rxxx.

5. Click the RAID tab.

6. In the Groups pane, you will see the RAID group that Sonnet created (not usable in a Windows system); click the group.

6. When the Delete Conﬁrmation window appears, click Yes.

7. Set up new RAID groups following the instructions on pages 9 and 10 of this manual.

WARNING: After selecting the DVRAID, R AID Level 4, or

RAID Level 5 option, configuration of a set of eight 1TB drives can take up to 4 hours (or up to 2 hours with 500GB drives).

8. Depending on how you conﬁgure your setup, a Disk Insertion window will appear at some point stating that there

is an unreadable volume; click Initialize, and then Disk Utility will open.

9. In the Disk Utility window, each RAID group you created using the ATTO Conﬁguration Tool will appear as a single volume. Select the volume, and then click the Erase tab at the top of the window.

10. Click Erase; a window will appear asking you to approve your choice.

11. Click Erase.

12. Repeat steps 7–11 for each remaining unformatted RAID group.

13. Close Disk Utility.

7. Select RAID Management > Delete Group from the application menu.

8. When the Delete Conﬁrmation window appears, click Yes.

9. Set up new RAID groups following the instructions on pages 9 and 10.

WARNING: After selecting the DVRAID, R AID Level 4, or

RAID Level 5 option, configuration of a set of eight 1TB drives can take up to 4 hours (or up to 2 hours with 500GB drives).

Note: If you do not select the quick format option, this process will take

much longer to complete.

16. Repeat steps 13–15 for each remaining “unallocated” disk.

17. Depending on how you conﬁgured the RAID groups,

the volumes may already be available to use. If you created a DVRAID, RAID Level 4, or RAID Level 5 group, conﬁguration will take much longer. You may check on the process by double-clicking the RAID group name in the lower pane of the ATTO Conﬁguration Tool window.

18. Once all the RAID groups have been formatted, they are ready to use.
