The best way is through the OS gui. If you trying to return the unit back to a factory fresh OS install with NO data it requires a debug cmd.

From Adaptec's Knowledgebase

The purpose of the reset button to allow the administrator to clear system settings to factory defaults. The button is designed to be pushed while the server is up and running normally. When pushed, the server will go through a shutdown process and restart. See the Administrator Guide to locate the reset button specific to your server model. The behavior of the reset button differs between software versions.

For servers running software version 2.6.050 and below, the reset button will cause the server to reboot in recovery mode. Once the server has successfully into recovery mode (this will be indicated by an alternating green and amber system LED), the administrator may connect to the server via HTTP to choose the settings to reset.

For servers running software version 3.0.099 and higher, the reset button functionality on Guardian OS servers do the following:

Reset TCP/IP settings to DHCP
Reset servername to SNAP

Often the first thing to try in resolving anomalous behavior on a Snap Server is to reset the server to factory defaults.

Resetting the Snap Server to Factory Defaults
The GuardianOS allows you to reset different components of the system.

Caution:
Each reset option requires a reboot of the server. To prevent possible data corruption or loss, make sure all users are disconnected from the Snap Server before proceeding.

Navigate to the Maintenance >> Factory Defaults screen, and select one of the following options, and then click Save.

A) Reset Network Configuration To Factory Defaults returns TCP/IP and other protocol settings to factory defaults.

B) Reset System Settings, Network, and Admin Passwords To Factory Defaults returns the admin and root passwords to the default value, returns TCP/IP and other protocol settings to factory defaults, eliminates all shares to all volumes, and returns settings for server name, date and time, users, groups, quotas, and the activation and configuration of CA eTrust Antivirus to factory default values.
When the server finishes rebooting, the Login dialog box opens. Enter the default admin password of admin, and click OK. The Initial Setup Wizard runs, allowing you to reset the server name, admin password, and IP address.

C) Set Default ACLs For Volume: resets the file and directory ACLs on selected volumes to reset the Everyone group to full control. Essentially, all users will be able to access all directories and files after the reset (within the confines of share access settings).

And Andy's favorite, you MUST HAVE THE OS GSU FILE.

Steps to perform a FRESH INSTALL on the Snap Server.

NOTE:
This will destroy all data and server settings on the Snap server.
At the DEBUG CONSOLE window (http://YourSnapServerName/admin/debug.cgi)
Enter the following command in the text field:

touch /nopivot

Press return

It will return a line

Reboot the snap server (Maintenance>Shutdown or Reboot)

Upon Reboot, the server will come up to Recovery Console in your web browser.
Recovery Console is indicated by the System LED alternating between amber and green.

At the RECOVERY CONSOLE screen, browse to your OS image (Recommended that this file be local on your workstation).
Select \"FRESH INSTALL\".

Note:
The whole operation may take 10 minutes or more. Please be patient.
