Property Definition
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.
