Select disk number (1 to 16)
Remove a disk from an existing configuration while ACS-8990 is online. This
function enables the administrator to shut down a potentially faulty disk. If a
spare drive is present, it will automatically be added (Default: None).
Statistic
Display system data in Monitor Utility output window (this information cannot
be viewed from the control panel). Data includes:
Current settings saved in NVRAM
Statistical analysis of read and write operations plus percentage of
cache hits
For full details of the Statistics output, see Appendix G, Statistics.
Expand Array
Select array to be expanded and then the number of disks in the new array.
Ensure that new disk capacity is equal to or larger than current on-line
capacity. To expand an array. To expand disk capacity:
Connect new disk
Use Expand Array menu to select the number of disks in the array
Go to the Slice menu (1.1.4). The new capacity will appear in a new
slice. So if you have already set up Slice0, Slice1and Slice2, the new
capacity will form Slice3. If no slices have been formed before (i.e.
there is only one partition: Slice0), the new capacity will be in Slice1.
Expanding an array increases array capacity but data may sometimes be lost.
You are strongly advised to make a system backup before proceeding.

RTC
Adjust Real Time Clock Settings.
When using the ACS-8990 for the first time, users will need to
set the "RTC parameters". Setting the RTC parameters will
enable the controller to have RTC function. When an event
occurs, the Log Event will therefore be able to record the event
real time.
