Controllers Properties And Tasks
Use the controllers properties and tasks window to view information about the controller and execute controller tasks.
The controller properties can vary depending on the model of the controller. Controller properties may include:
Property | Definition |
Status | These icons represent the severity or health of the storage
component. For more information, see Storage Component Severity.
|
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. |
Name | Displays the name of the controller. |
State | Displays the status of the controller. Possible values are:
|
Firmware Version | Displays the version of the firmware that is installed on the controller. |
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. |
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. |
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. |
Alarm State | Displays whether the alarm on the controller is enabled or disabled. |
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. |
Loadbalance | 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. 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. |
