Options for Adding a Second Channel

How you enable a second HP NetRAID channel depends on where you installed
your network operating system (NOS).
Option A. Your NOS is installed on an HP NetRAID logical drive. In
this case, you will not have to reinstall your NOS.
or
Option B. Your NOS is installed on a non-RAID hard disk drive
module controlled by the embedded SCSI controller. When you enable
HP NetRAID for two channels, the hard disk containing your NOS
becomes part of the RAID subsystem. You can no longer boot the existing
NOS, so you need to reinstall the NOS and restore your existing data.
These two options are discussed separately.

Option A: Your NOS is Installed on a RAID Logical Drive

There are two sets of instructions for enabling a second integrated HP NetRAID
channel when your NOS is installed on a RAID logical drive:
See Option A-1 if you started with SCSI A enabled for HP NetRAID
(the default mode), and now you want to enable SCSI B.
or
See Option A-2 if you started with SCSI B enabled for HP NetRAID,
and now you want to enable SCSI A.
Option A-1: To Enable SCSI B as Your Second HP NetRAID Channel
To configure SCSI B as a second HP NetRAID channel when your NOS is
installed on a RAID logical drive:
1. Back up all your drives, both RAID and non-RAID. You should not need
to restore your data, but backups are essential any time you change your
configuration.
CAUTION Do not proceed until you back up all your drives, both RAID
and non-RAID.
2. Log off all users, close all applications, and shut down the HP NetServer.
