Installation Overview
This guide describes the procedures for installing new hardware and software in
your LH 4/LH 4r NetServer. The hardware update takes 10 or 15 minutes. The
firmware update can take up to an hour, not including time taken by backing up
and restoring your hard disk drives, or by reinstalling the NOS or applications.
During the update procedure, you will see progress screens that indicate the action
underway.
During the software upgrade, you will:
• update system information
• reconfigure options like interrupt management and NetRAID details
• reinstall the NOS if necessary
NOTE Before attempting the upgrade procedure, you should be
familiar with the current and default NetRAID configurations
and with the BIOS options specified in the Setup utility. For
further information, refer to these topics on the HP NetServer
Online Documentation CD-ROM:
HP NetRAID Installation and Configuration Guide
HP NetRAID User Guide
Setup Utility (in LH 4/LH 4r Configuration section)
CAUTION The software update eliminates user-definable BIOS options
and the NetRAID configuration details. You must save these
details before you perform the software upgrade if you want to
restore these settings afterward.
