Table 11. Controller Properties (continued)
Property Definition
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

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.
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) Enterprise Key Management
(EKM)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:
