Controller Module—Additional Features
Battery Backup Unit
Each controller contains a two-cell Lithium ion nanopolymer battery backup unit (BBU). It provides power to the
controller module in the event of a power outage.
NOTE: For virtual disks, the controller firmware changes the data cache setting based on the state of the battery. If
the battery is missing or does not have sufficient charge, the controller flushes the cache and sets the write cache
attribute to Write Through for all virtual disks. When the battery is replaced, Write Back is re-enabled.
Storage Array Thermal Shutdown
The system automatically shuts down when system temperature exceeds the safe threshold. The battery backup unit
protects against data loss by providing power to offload cache to non-volatile memory in the event of power loss.
Temperature threshold values determine the temperature at which shutdown occurs. These thresholds cannot be
changed.
NOTE: It is not necessary to shut down any expansion enclosures attached to the storage array when thermal
shutdown occurs.
Table 2. Shutdown Threshold Type
Threshold Temperature ExceedingEvent Description
Nominal failure thresholdA critical event is set
Maximum failure thresholdShutdown of the system power supplies occurs within 3

System Password Reset
To reset the password, push and hold down the password reset switch for at least five seconds. The password is
deleted. You can change the password using MD Storage Manager.
For more information about setting your password, see the
Arrays Administrator's Guide
NOTE: If your system is iSCSI based, you can use the Modular Disk Configuration Utility to reset the system
password.
NOTE: The reset switch can be accessed by using a small object such as the tip of a pen.
You may need the following items to perform the procedures in this section:
•#2 Phillips screwdriver
•T8 and T15 Torx screwdrivers
•Wrist grounding strap connected to ground

– Cooling fan module
2.Ensure that all the cables are properly connected and that there are no damaged pins in the connectors.
3.Run the diagnostics available in Dell PowerVault Modular Disk (MD) Storage Manager.
49
4.In the AMW, select a component in the Hardware pane of the Hardware tab.
Certain 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 and
cache mirroring, the surviving controller can normally recover without data loss or shutdown.
Critical Conditions
The storage array generates a critical event if the RAID controller module detects a critical condition that could cause
immediate failure of the array and/or loss of data. The storage array is in a critical condition if one of the following
occurs:
•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 port
NOTE: If both RAID controller modules fail simultaneously, the enclosure cannot issue critical or noncritical event
alarms for any enclosure component.
Noncritical Conditions
A noncritical condition is an event or status that does not cause immediate failure, but must be corrected to ensure
continued 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 failed
Invalid Storage Array
The 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 RAID
controller module completes these initial tests and the controllers are booted successfully. If the RAID controller module
detects a non-Dell supported storage array, the controller does not startup. The RAID controller module does not
generate any events to alert you in the event of an invalid array, but the array status LED is lit with a flashing amber color
to indicate a fault state.
ECC Errors
RAID controller firmware can detect ECC errors and can recover from a single-bit ECC error whether the RAID controller
module is in a redundant or nonredundant configuration. A storage array with redundant controllers can recover from
multi-bit ECC errors as well because the peer RAID controller module can take over, if necessary.
50
The RAID controller module fails over if it experiences up to 10 single-bit errors, or up to three multi-bit errors.
PCI Errors
The storage array firmware can detect and only recover from PCI errors when the RAID controller modules are
configured for redundancy. If a virtual disk uses cache mirroring, it fails over to its peer RAID controller module, which
initiates a flush of the dirty cache.
