Chapter 6: MegaRAID Window and Menus
Make sure the capacity of the hotspare drive is equal to or larger than the capacity of the
disks in the array and that it is the same type of drive (SAS or SATA).
To remove a global hotspare disk, follow these steps:
1. In the left panel of the MEGARAID STORAGE MANAGER window, select a hotspare
drive.
2. Click on the OPERATIONS tab of the MEGARAID STORAGE MANAGER window to
display the tab (Figure6-10).
3. In the left pane of the tab, select the REMOVE GLOBAL HOTSPARE option.
4. Press the Go button.
This brings up a dialog box for you to confirm your deletion.
5. Check CONFIRM in the dialog box and then press OK to confirm your deletion.
6-5 Changing Adjustable Task Rates
Follow these steps if you need to change the adjustable rates for rebuilds and other
system tasks that run in the background:
1. Select the PHYSICAL VIEW tab in the left panel of the MEGARAID STORAGE MANAGER
window, and select a controller icon.
2. In the right panel of the MEGARAID STORAGE MANAGER window, select the
OPERATIONS tab, and select SET ADJUSTABLE TASK RATES.
The task rates appear in the right panel.
3. Enter changes, as needed, to the task rates for REBUILD RATE, BACKGROUND
INITIALIZATION (BGI) Rate (for fast initialization), and CHECK CONSISTENCY RATE (for
consistency checks).
NOTE: The hotspare drive will rebuild a failed drive even if it is SAS and the
array drives are SATA, or vice versa. Once the rebuild is complete, it is
recommended that you replace the new array member with a drive of the same
type.
NOTE: It is recommended that you leave the adjustable task rates at their
default settings to achieve the best system performance. If you raise the task
rates above the defaults, foreground tasks will run more slowly and it may seem
that the system is not responding. If you lower the task rates below the defaults,
rebuilds and other background tasks may run very slowly and may not complete
within a reasonable time. If you decide to change the values, record the original
default value here so you can restore them later, if necessary:
Rebuild Rate: ____________
Background Initialization (BGI) Rate: ____________
Check Consistency Rate: ____________
