Erase Utility
CAUTION:
Perform a backup before running the System Erase Utility. The utility sets the system
to its original factory state, deletes the current hardware configuration information, including
array setup and disk partitioning, and erases all connected hard drives completely. Refer to the
instructions for using this utility.
Run the Erase Utility if you must erase the system for the following reasons:
•
You want to install a new operating system on a server with an existing operating system.
•
You encounter an error when completing the steps of a factory-installed operating system installation.
To access the Erase Utility, use the System Erase button on the home screen of the SmartStart CD ("
Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server has
a single ROM that acts as two separate ROM images. In the standard implementation, one side of the ROM
contains the current ROM program version, while the other side of the ROM contains a backup version.
NOTE:
The server ships with the same version programmed on each side of the ROM.
Safety and security benefits
When you flash the system ROM, ROMPaq writes over the backup ROM and saves the current ROM as a
backup, enabling you to switch easily to the alternate ROM version if the new ROM becomes corrupted for
any reason. This feature protects the existing ROM version, even if you experience a power failure while
flashing the ROM.
USB support
HP provides both standard USB 2.0 support and legacy USB 2.0 support. Standard support is provided by
the OS through the appropriate USB device drivers. Before the OS loads, HP provides support for USB
devices through legacy USB support, which is enabled by default in the system ROM.
Legacy USB support provides USB functionality in environments where USB support is not available normally.
Specifically, HP provides legacy USB functionality for the following:
•
POST
•
RBSU
•
Diagnostics
•
DOS
•
Operating environments which do not provide native USB support
