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.
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.
|
Name | Displays the name of the controller. NOTE: For PowerEdge FD332
storage sled, the name is displayed as:
|
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 object
and clicking the Information tab. |
State | Displays the status of the controller.
Possible values are:
|
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:
|
Patrol Read State | Displays the current state of the
patrol read process. Possible values are:
|
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:
|
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:
|
Controller Tasks | Enables you to configure and manage the controller. |
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. |
