Introduction

Saving the Current Operating Environment

Before you start the upgrade, follow these instructions to preserve the current operating environment.

CAUTION You must back up all disks on your system - the disk containing the NOS and any RAID arrays. Failure to perform this step leaves you vulnerable to potential loss of data.

1.Back up all hard disks - both the hard disk containing the NOS, and any RAID arrays, using the backup utilities on your NOS. You will perform a restore later to replace this data.

2.You must write down all system configuration details from the Setup, Remote Management, and NetRAID utilities, as you will have to reconfigure them after the system software update. For a discussion of NetRAID implementation and usage details, refer to the HP NetRAID Installation and Configuration Guide and HP NetRAID User Guide manuals on the HP NetServer Online Documentation CD-ROM.

∗PowerFail Safeguard (Default is Enabled)

∗Disk Spin Up Timings (Default is Automatic Spinup)

∗Cache Flush Timings (Default: every 4 seconds)

∗Rebuild Rate (Default: 50%)
