– Transition Rate: High, Medium, Low
– Reassigned Block Threshold
– Error Block Threshold
– Enable Media Patrol
– Enable Auto Rebuild
In addition, you can use the scheduler to configure these settings. Use the scheduler
according to the following parameters.
8.1.1 Rebuild the settings
To change the rebuild settings in the Background Activity Settings menu:
1.
Use the Rebuild Rate drop-down menu and select a rate:
– Low - Less system resources are used for rebuilding, and more system resources are
used for data read / write operations.
– Medium - The system resources between the rebuild and data read / write
operations are balanced.
– High - More system resources are used for rebuilding, and less system resources are
used for data read / write operations.
2. To enable Auto Rebuild (rebuild automatically when you replace a failed hard disk with a
new one). Select the
Enable Auto Rebuild check box.
3. Click the Submit button.
Rebuild rate
When you rebuild a disk array, you are actually rebuilding the data on a physical drive (i.e., a
physical hard disk).
–
When a physical drive in a disk array fails, a spare drive with sufficient capacity is
available and the disk array automatically begins to rebuild with a spare drive.
– If a spare drive with sufficient capacity is not available, but the automatic rebuild feature
is enabled, the disk array begins to rebuild automatically after you remove the failed
physical drive and install an unconfigured physical drive in the same slot.
– If a spare drive with sufficient capacity is not available, and the auto-rebuild feature is
disabled, you must replace the failed drive with an unconfigured physical drive and
perform a manual rebuild.
8.1.2 Background synchronization rate
Synchronization is automatically applied when a redundant logical drive is created.
Recalculate redundant data synchronously to ensure that the work data on the physical drive
is properly synchronized.
Background synchronization rate
To change the background synchronization rate in the Background Activity Settings menu:
1.
Click the Synchronization Rate drop-down menu and select a rate:
– Low - Less system resources are used for synchronization, and more system
resources are used for data read / write operations.
– Medium- The system resources between the synchronization and data read / write
operations are balanced.
– High - More system resources are used for synchronization, and less system
resources are used for data read / write operations.
2. Click the Submit button.
8.1.3 Logical drive initialization
Initialization is a foreground activity because you can not access a logical drive while
initializing.
