Controllers Properties And Tasks

Use the controllers properties and tasks window to view information about the controller and perform controller tasks.

NOTE: The firmware and drivers listed in the Server Administrator Release Notes, see the minimum supported version for these controllers. Later versions of the firmware and drivers are also supported. For the most recent driver and firmware requirements, contact your service provider.

The controller properties can vary depending on the model of the controller. Controller properties may include:

Table 1. Controller Properties
Property	Definition
ID	Displays the ID assigned to the controller by Storage Management. Storage Management numbers the controllers attached to the system starting with zero. This number is the same as the controller ID number reported by the `omreport` CLI Command. For information on Command Line Interface, see the Server Administrator Command Line Interface User’s Guide .
Status	These icons represent the severity or health of the storage component. For more information, see Storage Component Severity . — Normal/OK — Warning/Non-critical — Critical/Failure/Error
Name	Displays the name of the controller. NOTE: For PowerEdge FD332 storage sled, the name is displayed as: Single controller — PERC FD33xS (Integrated RAID Controller <X> in Front Chassis Slot <Y> , where X displays the controller number and Y displays the front chassis slot number. Dual controller — PERC FD33xD (Integrated RAID Controller <X> in Front Chassis Slot <Y> , where X displays the controller number and Y displays the front chassis slot number.
Slot ID	Displays the slot to which the controller is attached. For PowerEdge FD332 storage sled, the name is displayed as: PCI Slot <Y> <X>, where Y displays the front chassis slot number and X displays the controller number. NOTE: You can also identify the slot ID by selecting the System > Main > System Chassis > Slots object and clicking the Information tab.
State	Displays the 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	Displays the version of the firmware that is installed on the controller. NOTE: Storage Management displays Not Applicable on some controllers for which the firmware version cannot be obtained.
Minimum Required Firmware Version	Displays the minimum firmware version that is required by Storage Management. This property is displayed only if the controller firmware does not meet the minimum requirement.
Driver Version	Displays the version of the driver that is installed on the controller. NOTE: Storage Management displays Not Applicable on some controllers for which the driver version cannot be obtained.
Minimum Required Driver Version	Displays the minimum driver version that is required by Storage Management. This property is displayed only if the controller driver does not meet the minimum requirement.
Number of Connectors	Displays the number of connectors on the controller. Each connector can be attached to physical disks or an enclosure. Depending on the controller type, the connector can be either a SCSI channel or a SAS port.
Rebuild Rate	Rebuild rate is the percentage of resources available on a system dedicated to rebuild a failed disk when necessary. For more information on rebuild rate, see Setting The Rebuild Rate . NOTE: The value for the Revertible Hot Spare operation is the same as the value set for the Rebuild Rate property.
BGI Rate	The background initialization (BGI) rate is the percentage of resources available on a system dedicated to perform the background initialization of a virtual disk after it is created. For more information on BGI rate, see Setting Background Initialization Rate .
Check Consistency Rate	The check consistency rate is the percentage of resources available on a system dedicated to perform check consistency on a redundant virtual disk. For more information, see Performing A Check Consistency .
Reconstruct Rate	The reconstruct rate is the percentage of resources available on a system dedicated to reconstruct a disk group after adding a physical disk or changing the RAID level of a virtual disk residing on the disk group. For more information on reconstruct rate, see Setting The Reconstruct Rate.
Abort Check Consistency on Error	Enables you to stop the Check Consistency operation on error. This property is available only on controllers that have controller firmware version 6.1 and later.
Allow Revertible Hot Spare and Replace Member	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 Enabling Revertible Hot Spare.
Load Balance	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.
Auto Replace Member on Predictive Failure	Enables the automatic copying of data from a physical disk to a hot spare in case of predictive failure. Use this property in conjunction with the Allow Revertible Hot Spare and Replace Member property.
Redundant path view	Indicates whether Storage Management has detected a redundant path configuration. Storage Management detects a redundant path configuration when both controller ports are connected to the same enclosure that is in a unified mode. For more information, see Setting The Redundant Path Configuration .
Encryption Capable	Indicates whether the controller has the capability to support encryption. Possible values are Yes and No.
Encryption Key Present	Indicates whether the controller has an encryption key established. Possible values are Yes and No.
Encryption Mode	Indicates whether the controller is using Local Key Management (LKM) or None. For more information, see Managing The Encryption Key .
T10 Protection Information Capability	Indicates whether the controller supports data integrity. Possible values are Yes and No.
Cache Memory Size	Displays the size of the cache memory on the controller.
Patrol Read Mode	Displays the Patrol Read Mode setting for the controller. Possible values are: Auto — Patrol read runs continuously on the system. When one iteration of the patrol read is complete, the next patrol read is scheduled to start within a period of time specified by the controller. You do not have the option of manually starting or stopping the Patrol Read in this mode. Manual — Allows you to manually start or stop the patrol read process. Disabled — Indicates that the patrol read process is disabled. For more information about patrol read, see Setting The Patrol Read Mode and Starting And Stopping Patrol Read .
Patrol Read State	Displays the current state of the patrol read process. Possible values are: Ready — The patrol read process is enabled and runs when next scheduled or when manually initiated. Active — The patrol read process is running. Stopped — The patrol read has been stopped. For more information about patrol read, see Setting The Patrol Read Mode .
Patrol Read Rate	Displays the percentage of system resources dedicated for running the Patrol Read operation. Patrol Read Rate changes the amount of system resources assigned for the patrol read task. The Patrol Read Rate can be configured between 0% and 100%, where: 0% — indicates the lowest priority for controllers and has the least impact on the system performance. 100% — indicates the highest priority for controllers and has a greater impact on the system performance.
Patrol Read Iterations	Displays the number of Patrol Read Iterations. For more information about patrol read, see Setting The Patrol Read Mode .
Cluster Mode	Indicates whether the controller is part of a cluster configuration.
Persistent Hot Spare	Displays if the hot spare is persistent. The possible values are: Enabled — The slot corresponding to the hot spare drive is persistent. Any drive in the slot functions as a hot spare if the drive is qualified to be a hot spare. If the drive contains foreign data, it is overwritten. Disabled — The slot corresponding to the hot spare drive is not persistent. If the drive is removed from the slot and any drive is inserted, the slot stops functioning as a hot spare. You need to manually assign the drive as a hot spare again.
Controller Tasks	Enables you to configure and manage the controller. For more information about controller tasks, see Controller Tasks.
Available Reports	Enables you to view patrol read report, check consistency report, slot occupancy report, and physical disk firmware version report. For more information on available reports, see Available Reports .
Current Controller Mode	Displays the mode of the hardware controller that is selected. The possible values are RAID or HBA. To change the controller mode, see Changing The Controller Mode .
Front Chassis Slot	Displays the front chassis slot number. This property is applicable only for PowerEdge FD332 storage sled. For more information on PowerEdge FD332, see the Dell PowerEdge FD332 Owner's Manual at dell.com/poweredgemanuals.
