18 Display Properties of a Controller, Array, Logical Device and a Physical Device
This section lists the display properties of a controller, accelerator, array, logical device and physical device.
Property | Tooltip Details |
|---|---|
Model | Model of the Controller |
Status | The status of the controller based on its resources. |
| Mode | Mode of the controller on which it is operating. |
Driver Version | Current version of driver installed on the system. |
Driver Name | Driver name describes the name of the driver. |
I2C Address | I2C address describes the Inter-Integrated Circuit(I2C) slave address. |
| Reboot Required Reasons | Indicates the reason why a controller cold reboot is required. |
Rebuild Priority | Rebuild priority determines the urgency with which the controller treats an internal command to rebuild a failed logical drive. At the low setting, normal system operations take priority over a rebuild. At the medium setting, rebuilding occurs for half of the time, and normal system operations occur for the rest of the time. At the medium high setting, rebuilding is given a higher priority over normal system operations. At the high setting, the rebuild takes precedence over all other system operations. |
Expand Priority | Expand Priority setting determines the urgency with which the controller treats an internal command to expand an array. At the low setting level, normal system operations take priority over an array expansion. At the medium setting, expansion occurs for half of the time, and normal system operations occur for the rest of the time. At the high setting, the expansion takes precedence over all other system operations. |
Consistency Check Priority | Consistency Check Mode is an automatic background process that ensures that you can recover data if a drive failure occurs. The scanning process checks physical drives in fault-tolerant logical drives for bad sectors and it also verifies the consistency of parity data if applicable. The available modes are disable, high, or idle. The idle mode must also specify a delay value. When set to high, the check will run in parallel to host I/O and may have an impact on performance. When set to idle, the check will only run during periods of host inactivity and will not impact performance. |
Consistency Check Delay | Consistency Check Delay determines the time interval for which a controller must be inactive before a consistency check is started on the physical drives that are connected to it. The value can be between 0 and 30 to specify the duration of the delay in seconds. A value of 0 disables the scan. The default value is 3 seconds. |
Parallel Consistency Check Count | Parallel consistency check count describes the number of logical devices on which the controller will perform consistency check in parallel. |
Consistency Check Inconsistency Notify | Consistency Check Inconsistency Notify property enables the event notification messages and serial debug log messages for mirrored volumes. |
Spare Activation Mode | Spare activation mode feature enables the controller firmware to activate a spare drive. The firmware starts rebuilding a spare drive only when a data drive fails, if the mode is set to Failure. With the predictive failure activation mode, rebuilding can begin before the drive fails when a data drive reports a predictive failure (SMART) status which will reduce the likelihood of data loss that could occur if an additional drive fails. |
| UEFI Health Reporting Mode | UEFI Health Reporting Mode allows the user to change whether to
report UEFI driver health error messages on the boot screen and halt the
boot process or not. The UEFI Health Reporting Mode can be either
“Enabled” or “Disabled”. The default mode is “Enabled”, which reports all the UEFI driver health error messages on the boot screen and halts the boot process. The “Disabled” mode does not report any UEFI driver health error messages on the boot screen and continues the booting regardless of the errors. |
Drive Cache | |
Write Cache Policy for Configured Drives | This option allows to configure the write cache policy on a controller. Setting to default allows the controller to optimize the drive write cache policy of those drives. Enabling drive write cache can increase write performance but risks losing the data in the cache on sudden power loss. Setting the policy to “unchanged” means that the controller will make no changes to the drive’s default power-on write cache policy. |
