SCC Appliance: How to Rebuild your RAID Array
Introduction
Occasionally you may need to rebuild the RAID array on your appliance. A few examples of why you
would need to do this are:
•
•
•
hardware malfunction caused the array to become corrupt
you are having problems imaging the appliance
you have been instructed to so by Secure Computing Technical Support
Warning: Rebuilding the RAID array will erase all data on the drives, so rebuild the array only when
absolutely necessary.
1.
Power on the appliance. While the appliance is booting, press Ctrl-r to run the RAID
Configuration Utility when prompted.
Note: Verify that the appliance has either the PERC5 or PERC6 Controller. If it does not, this article will not
apply to the appliance.
2.
Check to see if the appliance has a configured Virtual Disk.

o
If the appliance has a configured RAID array, the Disk Group will look similar to the
image below, with a Virtual Disk (array) and two or more Physical Disks.
If the appliance had a RAID failure, it may not have a configured Virtual Disk and
Controller 0 may say No Configuration Present!. Skip to step 4 if this is the case.
3.
Delete the Virtual Disk.
a.
b.
Highlight Virtual Disk 0 and press F2 on your keyboard. A pop-up appears.
Select Delete VD and press Enter.
c.
Press Enter to remove the RAID array.
The RAID Configuration Utility will now say No Configuration Present!.
4.
Create a new Virtual Disk.
a.
Press F2 and select Create New VD.
You will see output similar to below.
•
•
If the appliance has two hard drives, you need to configure RAID-1
(mirroring).
If the appliance has three or more hard drives, you need to configure RAID-5
(striping with parity).
b.
Select the physical drives that will be put into the array. Highlight each drive and press
Alt.
Note: The example screen shots have extra drives available that your appliance will
not have, so please disregard them.
c.
Tab over to OK and press Enter to create the new Virtual Disk.
Note: This may take a couple seconds, so be patient.
5.
Initialize the array.
a.
b.
Highlight Virtual Disk 0 and press F2.
Select Initialization > Start Init..
c.
Press Enter to start initialization initialization process.
Initialization could take up to 30-60 minutes. You will see a progress indicator as shown
below.
6.
Press Esc to exit the RAID Configuration Utility when initialization is complete.
Now you will be able to image the appliance with the appropriate software.
