Changing the System Name of a NonStop BladeSystem

Notes, Cautions and Warnings

CAUTION: If you change the system name or system number on an existing system and are

running complex applications such as NonStop SQL/MP, HP NonStop Transaction Management

Facility (TMF), Distributed Systems Management/Software Configuration Manager (DSM/SCM),

or HP NonStop Open System Services (OSS), you must reconfigure the applications with the new

system name and take additional precautions to avoid losing access to the data.

Refer to these manuals for more information:

• NonStop SQL/MP Installation and Management Guide

• HP NonStop TMF Planning and Configuration Guide

• DSM/SCM User’s Guide

• Open System Services Management and Operations Guide

Preparation

Read through this entire procedure before beginning.

1. Be sure you have the credentials to log on to the components that need to be changed. For

example:

• The Administrator ID and password for the NonStop system console

• The passwords for the root ID and the user ID on the CLIMs and the OA.

• A SUPER group user ID and password for the NonStop system.

2. Record the current SYSnn running on the system.

3. Record the IP addresses of these system components in case you need to refer to them during

this procedure:

• CLIMs

• c7000 ServerNet switches

• Onboard Administrators

• NonStop system consoles

4. Take an OSM inventory of the system. Refer to the OSM Service Connection online help for

instructions on saving the system inventory to a file. You can use the saved file to make sure

that the contents of system are the same when you bring it back up later in this procedure.

5. Save the current configuration database. For instructions, refer to the NonStop BladeSystem

Hardware Installation Manual. If necessary, you can fall back to a known, stable configuration

by loading the system from the saved configuration file.
