4. In the AMW, select a component in the Hardware pane of the Hardware tab.5. Select Hardware → RAID Controller Module → Advanced → Run Diagnostics → RAID Controller Module.Controller Failure ConditionsCertain events can cause a RAID controller module to fail and/or shut down. Unrecoverable ECC memory or PCI errors,or critical physical conditions can cause lockdown. If your RAID storage array is configured for redundant access andcache mirroring, the surviving controller can normally recover without data loss or shutdown.Critical ConditionsThe storage array generates a critical event if the RAID controller module detects a critical condition that could causeimmediate failure of the array and/or loss of data. The storage array is in a critical condition if one of the followingoccurs:• More than one fan has failed• Any midplane temperature sensors in the critical range• Midplane/power supply module failure• Two or more temperature sensors are unreadable• Failure to detect or unable to communicate with peer portNOTE: If both RAID controller modules fail simultaneously, the enclosure cannot issue critical or noncritical eventalarms for any enclosure component.Noncritical ConditionsA noncritical condition is an event or status that does not cause immediate failure, but must be corrected to ensurecontinued reliability of the storage array. Examples of noncritical events include the following:• One power supply module has failed• One cooling fan module has failed• One RAID controller module in a redundant configuration has failed• A battery has failed or has been removed• A physical disk in a redundant virtual disk has failedInvalid Storage ArrayThe RAID controller module is supported only in a Dell-supported storage array. After installation in the storage array,the controller performs a set of validation checks. The array status LED is lit with a steady amber color while the RAIDcontroller module completes these initial tests and the controllers are booted successfully. If the RAID controller moduledetects a non-Dell supported storage array, the controller does not startup. The RAID controller module does notgenerate any events to alert you in the event of an invalid array, but the array status LED is lit with a flashing amber colorto indicate a fault state.ECC ErrorsRAID controller firmware can detect ECC errors and can recover from a single-bit ECC error whether the RAID controllermodule is in a redundant or nonredundant configuration. A storage array with redundant controllers can recover frommulti-bit ECC errors as well because the peer RAID controller module can take over, if necessary.50
