About the Configuration ToolThe ATTO Configuration Tool is the utility program that displays information about installed controllers, drivers and drives in your Fusion storage system, and provides the means to configure and manage them.

This program executes under:

•MacOS®X10.4orlater•Windows®7/Server2008/Vista®/Server2003/XP•Linux®2.4and2.6kernels,x86andx64

Note:Java version 1.5 or later must be installed.

The ATTO Configuration Tool displays:

•ThenameoftheSonnetRAIDcontroller(listed as an ExpressSAS Rxxx adapter)

•InformationaboutthedriverscontrollingtheSonnetRAIDcontroller,includingversioninformationforboththecurrentlyexecutingdriverandtheflashimage

•InformationaboutFusiondriveenclosuresattachedtotheSonnetRAIDcontroller(exceptD400RAID,D800RAID,andR800RAID)suchasfanandpowersupplystatus

•InformationaboutdriveswithinattachedFusiondriveenclosures

You may use the Configuration Tool to:

•ManageRAIDgroups•ConfigureRAIDEventnotifications•ModifytheRAIDcontroller’sNVRAMsettings•Reverttodefaultfactorysettings•UpdatetheRAIDcontroller’sflashimage•Obtaindrivehealthinformation•Obtaindriveenclosurehealthinformation

ThefactorysettingsonyourSonnetRAIDcontrollerprovideexcellentperformanceforawiderangeofapplications.However,someapplicationsmaybenefitfrommodificationofthecontroller’sNVRAMsettingsthattunethecontrollerforaspecificperformancerange.

Configuration Tool Launch 1. Locatetheapplicationiconinthefoldercreatedduring

installation.

2.Double-clicktheATTOConfigurationicontostarttheapplication.

Note:The Sonnet RAID controller is designed to operate properly using factory settings. Entering invalid or incorrect NVRAM settings may cause your Sonnet RAID controller to function incorrectly.

1.2 RAID Group Setup and Management

The ATTO Configuration Tool enables you to configure disk storage into RAID groups or Hot Spare drives.

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

UsetheATTOConfigurationTooltosetupRAIDgroupsonyourSonnetRAIDcontrollerinoneofthefollowingRAIDlevels:

•JBOD•RAIDLevel0•RAIDLevel1•RAIDLevel4•RAIDLevel5•RAIDLevel6•RAIDLevel10•DVRAID™

DVRAIDRAIDgroupsmaybesetupautomaticallybytheATTOConfigurationTool.AllotherRAIDconfigurationsrequirecustomizedinput;Sonnet recommends Custom RAID group setup.

EachRAIDgroupmaybedividedintooneormorepartitions;eachpartitionappearstotheyourcomputerasavirtualdisk.

YoumayusethecommandlineinterfacepanefromtheRAID CLItabintheATTOConfigurationTooltosetupormodifyvariousparameters(RefertoAppendixA).However, using the menu-based procedures listed in this chapter is the preferred method for setting up RAID configurations for the Fusion storage system.

1.9 SNMP Configuration

SNMP is a standard network protocol that provides the ability to monitor SNMP enabled systems from anywhere on the network. Once configured, 3rd party MIB (Management Information Base) browsers on a Management Station can be used to retrieve the current configuration and receive TRAP messages when significant events occur. Via the Configuration Tool, SNMP is supported only for the Sonnet 3 Gb/s RAID controller (listed as an ExpressSAS R380).

TheATTOSNMPagenthastwomodes,dependingonyourconfiguration.IftheonlySNMPagentonyourserveristheATTOagent,themodeshouldbeEnabled.IfyouhaveotherSNMPagentsrunningandyouwantthemtointegratetheirdataintoasingletreeofinformationorifyouwanttouseadvancedSNMPfeatures,chooseSubAgentmode.

•SubAgent-AsoftwareprocessonthesystembeingmonitoredthatrespondstoSNMPqueriesfromanotheragent,insteadofaMIB(ManagementInformationBase)browser.TherequestfromtheotheragentisgeneratedwhenitiscontactedbyaMIBbrowser.

DetailsThe ATTO SNMP agent supports protocol versions 1 and 2c. Communication with the agent requires UDP over IPv4. The ATTO specific information can be found under “attotech” in the “enterprises” node (1.3.6.1.4.1.4547). Read-only support is provided.

Enabled ModeThismodeofoperationprovidesManagementStationswithbasicinformationforthestandardOID(ObjectIDentifier)tree,aswellastheATTOspecificinformation.Whilethismodewillalsoworkifasystemserviceisinstalledandrunning,theATTOagentmustbeconfiguredtolistenonadifferentportthanthesystemservicetoensurebothfunctionproperly.ThismodeisrequiredtosupportSNMPifthesystemSNMPservice(suchas,WindowsSNMPserviceorsnmpdforOSXandLinux)isnotalreadyrunning.

Forexample,ifthesystemservicesupportsversion3oftheprotocol,allcommunicationoverthenetworkbetweentheManagementStationandtheservicecanbeencryptedusingthedesiredprivacyoptionsofversion3.ThesystemservicewillthencommunicatetotheATTOagentusingoneofthesupportedprotocols.

Note:For security purposes, the ATTO agent will only respond to requests through the loopback interface when in subagent mode. If the system service is stopped, the ATTO agent will be inaccessible from any other host on the network.

Note:Other features that are not directly supported by the ATTO agent, but can be enabled with this configuration include source address filtering and stronger authentication than simple community strings provide. All of these features depend on properly configuring the system service, and are beyond the control of the ATTO agent. Refer to the documentation for the system service to determine how to enable these features.

Note:On Windows Vista Service Pack 1 and Windows Server 2008, a bug in the Microsoft SNMP service prevents subagent mode from working correctly. This is a known issue that requires a hotfix: http://support.microsoft.com/kb/950923. The bug has been fixed in Service Pack 2. Enabled mode is not affected, nor is the Net-SNMP service if that is being used as a replacement for the Microsoft service.

Note:The Net-SNMP service that ships with Mac OS X 10.4 lacks the functionality needed to support subagent mode. To work around this, you need to use the enabled mode or build the Net-SNMP package from source with proxy support enabled.

Note:The System Service and TRAP Service states are not updated dynamically as they change in the system. They can be manually updated at any time by clicking Refresh.

Note:In order to properly secure access to the agent from the local machine, it is suggested you change the default string in the Communities list before committing the default settings.

Note:In subagent mode, only a single community can be specified since that is the community used by the Master Agent when talking to the ATTO SNMP subagent. The communities that Management Stations must use are configured through the system service.

Note:For added security in subagent mode, you should change the default community string. The agent cannot tell the difference between a local Management Station request and a request from the system service, which means a local user can bypass the authentication checks done by the system service if they know this community string and the agent’s port.

Send Authentication TRAPWhenchecked,theagentwillsendaTRAPtotheconfiguredTRAPdestinationsindicatingthataManagementStationattemptedtocontacttheagentandusedacommunitystringthatisnotinthecommunitylist.

Note:In subagent mode, this may only be useful for debugging. The system service will perform Management Station authentication based on its configuration, and only forward the request to the ATTO agent once the Management Station is authenticated. Since the system service is reconfigured as needed to use the community string on this pane when forwarding requests, there should not be authentication errors when the agent processes requests from the system service. The system service usually has the same option that can be enabled to see these authentication failures.

2.2 ATTO Disk Benchmark Troubleshooting

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

•UseWindowsDeviceManagertocheckandverifythatalldrivesarevisibletotheoperatingsystem.

•Ifdrivesarenotlisted,checktheconnectionsbetweenthedriveenclosureandtheRAIDcontrollercard,andverifythatalldrivesarefullyseatedintheirbays.

•Makesurethattheenclosureispoweredupandhascompleteditsselfcheckbeforebootingyourcomputer.

•RebootyoursystemanytimeyoumakechangestoaRAIDgroup(aftertheRAIDgrouphasbeenrebuilt).

•Asalastresort,youmayusetheATTOBootConfigurationUtilitytolowlevelformatatroublesomedevice.However,thiserasesallinformationonthedisk.

•Haveyoupartitionedyourdrive,andthenactivatedthatpartition?

•Didyouformatthedrivesforusewithyouroperatingsystem?

Appendix A - CLI ASCII-Based Interface

The RAID CLI tab enables experienced users to send Command Line Interface (CLI) commands to the Sonnet RAID controller to configure, test, and otherwise interact with attached storage.

WARNING:Do not use CLI unless you are directed to by a Sonnet technician, as changing parameters may cause

loss of data and/or disruption to performance and reliability of the Sonnet RAID controller. The ATTO Configuration Tool interface is the preferred method to operate and manage the Sonnet RAID controller.
