Changing Adjustable Task Rates
If you want to change the Rebuild rate and other task rates for a controller, you must first log onto the server in Full Access mode. (LSI recommends not changing the adjustable task rates from their defaults.) Then follow these steps to set the adjustable task rates:
- Select a controller icon in the Physical tab or the Logical tab in the left panel of the MegaRAID Storage Manager main menu screen.
- Select Go To->Controller->Set Adjustable Task Rates from the menu bar, as shown in Figure 25.
Figure 25 Set Adjustable Tax Rates Menu
The Set Adjustable Task Rates dialog box appears, as shown in Figure 26.Figure 26 Set Adjustable Task Rates Dialog Box
- Enter changes, as needed, to any of the task rates:
- Rebuild Rate. Enter a number from 0 to 100 to control the rate at which a rebuild will be performed on a drive when one is necessary. The higher the number, the faster the rebuild will occur (and the system I/O rate may be slower as a result).
- Patrol Rate. Enter a number from 0 to 100 to control the rate at which patrol reads will be performed. Patrol read monitors drives to find and resolve potential problem that might cause drive failure. The higher the number, the faster the patrol read will occur (and the system I/O rate may be slower as a result).
- Background Initialization (BGI) Rate Enter a number from 0 to 100 to control the rate at which virtual drives are initialized “in the background.” Background initialization establishes mirroring or parity for a RAID virtual drive while allowing full host access to the virtual drive. The higher the number, the faster the initialization will occur (and the system I/O rate may be slower as a result).
- Check Consistency Rate. Enter a number from 0 to 100 to control the rate at which a consistency check is done. A consistency check scans the consistency data on a fault tolerant virtual drive to determine if the data has become corrupted. The higher the number, the faster the consistency check is performed (and the system I/O rate may be slower as a result).
- Reconstruction Rate. Enter a number from 0 to 100 to control the rate at which reconstruction of a virtual drive occurs. The higher the number, the faster the reconstruction occurs (and the system I/O rate may be slower as a result).
- Click Go to accept the new task rates.
- When the warning message appears, click OK to confirm that you want to change the task rates.
