Use this window to view information about the controller and execute controller tasks.

Controller Properties

The controller properties can vary depending on the model of the controller. Controller properties may include:

Property
Definition
Status
These icons represent the severity or health of the storage component.



Normal/OK

Warning/Non-critical

Critical/Fatal
See "Storage Component Severity" for more information.
ID
This property displays the controller ID assigned to the controller by Storage Management. Storage Management numbers the
controllers attached to the system starting with zero.
Name
This property displays the name of the controller.
State
This property displays the current status of the controller. Possible values are:
Ready — The controller is functioning normally.
Degraded — The controller has encountered a failure and is operating in a degraded state.
Failed — The controller has encountered a failure and is no longer functioning.
Firmware Version
This property displays the version of the firmware that is currently installed on the controller.
NOTE: On some controllers, Storage Management may not be able to obtain the firmware version. In this case, Storage
Management displays Not Applicable.
Minimum Required
Firmware Version
This property displays the minimum firmware version that is required by Storage Management. This property is only displayed if the
controller firmware does not meet the minimum requirement.
The firmware and drivers listed in the Readme file refer to the minimum supported version for these controllers. Later versions of
thefirmwareanddriversarealsosupported.SeetheDell™Supportwebsiteatsupport.dell.comforthemostrecentdriverand
firmware requirements.
Driver Version
This property displays the version of the driver that is currently installed on the controller.
NOTE: On some controllers, Storage Management may not be able to obtain the driver version. In this case, Storage Management
displays Not Applicable.
Minimum Required
Driver Version
This property displays the minimum driver version that is required by Storage Management. This property is only displayed if the
controller driver does not meet the minimum requirement.
The firmware and drivers listed in the Readme file refer to the minimum supported version for these controllers. Later versions of
the firmware and drivers are also supported. See the Dell Support website at support.dell.com for the most recent driver and
firmware requirements.
Number of
Connectors
This property displays the number of connectors the controller has. Each connector can be attached to physical disks or an
enclosure.
 Rebuild Rate
The rebuild rate is the percentage of the system's resources dedicated to rebuilding a failed disk when a rebuild is necessary. See
"Set Rebuild Rate" for more information.
NOTE: Revertible Hot Spare operation will have the same rebuild rate that you set here.
BGI Rate
The background initialization (BGI) rate is the percentage of the system's resources dedicated to performing the background
initialization of a virtual disk after it is created. See "Set Background Initialization Rate" for more information.
Check Consistency
Rate
The check consistency rate is the percentage of the system's resources dedicated to performing a check consistency on a redundant
virtual disk. See "Check Consistency" for more information.
Reconstruct Rate
The reconstruct rate is the percentage of the system's resources dedicated to reconstructing a disk group after adding a physical
disk or changing the RAID level of a virtual disk residing on the disk group. See "Set Reconstruct Rate" for more information.
Abort check
consistency on error
This property enables you to stop the Check Consistency operation on error rather than continuing. This property is available only
on controllers that have controller firmware version 6.1 and later.
Revertible Hot Spare
This property enables the automatic copying of data from a physical disk to a hot spare (in case of predictive failure) or from a hot
spare to a physical disk (in case of replacement of a degraded disk). For more information, see "Revertible Hot Spare."
Loadbalance
This property provides the ability to automatically use both controller ports or connectors connected to the same enclosure to route
I/O requests. This property is available only on SAS controllers that have controller firmware version 6.1 and later. For more
