User's Manual

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. For the most recent driver and firmware requirements, see support.dell.com.
Number of
Connectors
This property displays the number of connectors the controller has. 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
The rebuild rate is the percentage of the system's resources dedicated to rebuilding a failed disk when a rebuild is necessary. For more
information, see Set Rebuild Rate.

NOTE: Revertible Hot Spare operation has 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. For more information, see Set Background Initialization Rate.
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. For more information, see Check Consistency.
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. For more information, see Set Reconstruct Rate.
Alarm State
This property displays whether the controller's alarm is enabled or disabled.

NOTE: This property is displayed only for SCSI storage controllers.
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 information,
see Redundant path view.
Auto replace on
predictive failure
In case of predictive failure, this property enables the automatic copying of data from a physical disk to a hot spare. Use this property
in conjunction with the Revertible Hot Spare 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
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 Manage Encryption Key.
Cache Memory
Size
This property displays the size of the controller's cache memory.
Patrol Read Mode
This property displays the Patrol Read mode setting for the controller. Possible values are:
Auto—When set to Auto, a 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 Auto mode.
Manual—When set to Manual, you can start or stop the Patrol Read process.
Disabled—This property indicates that the Patrol Read process is disabled.
For more information about Patrol Read, see Set Patrol Read Mode and Start and Stop Patrol Read.
Patrol Read State
This property 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 currently running.
Stopped—The Patrol Read has been stopped.
For more information about Patrol Read, see Set Patrol Read Mode.
Patrol Read
Iterations
This property displays the number of Patrol Read iterations.
For more information about Patrol Read, see Set Patrol Read Mode.
Cluster Mode
This property indicates whether the controller is part of a cluster configuration.
SCSI Initiator ID
This property displays the SCSI ID of a SCSI controller. The default value is usually 7. You can change the default value in the BIOS. In
cluster mode, the value is 6 or 7.
The SCSI ID is not displayed on the PERC 4/IM controllers. Use the BIOS on these controllers to identify the SCSI ID.
Persistent Hot
Spare
This property appears only for PERC H700 and H800 controllers. 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.
