Add a disk to an existing configuration while ACS-8960 is online (Default: None).
6.6 Remove
Disk
Select disk number (1 to 16)
Remove a disk from an existing configuration while ACS-8960 is online. This
function enables the administrator to shutdown a potentially faulty disk. If a spare
drive is present, it will automatically be added (Default: None).
6.7 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
6.8 Expand
Array
Select array to be expanded (Array 1 to Array 4) 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.
6.9 Update
ROM
Use this option to update the ACS-8960 programmable firmware. See
Updating the
Firmware
later in this chapter.
Configuration changes made in the RAID Functions menu must be saved to the
ACS-8960 non-volatile memory for the changes to take effect. This is done in
the NVRAM menu accessed from the Main menu.. See Saving Configurations
later in this chapter.
