Changing the System Name of a NonStop System for H-Series RVUs
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 any CLIMs.
• 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 that you need to change during this
procedure:
• P-switch ServerNet Switch Boards
• All CLIMs
• IOAM Enclosure ServerNet Switch Boards
• VIO modules
• 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 appropriate hardware
installation manual for your system. If necessary, you can fall back to a known, stable
configuration by loading the system from the saved configuration file.

Enter these SCF commands to change the system name:
6. Start SCF:
SCF
7. Specify the Kernel subsystem and display the current settings:
-> ASSUME SUBSYS $ZZKRN
-> INFO, DETAIL
8. Type a new system name that is unique (within the site’s Expand network):
-> ALTER, SYSTEM_NAME \sys-name
9. Confirm the system name change:
-> INFO, DETAIL
The results of the INFO command show that the operation is pending until the system load.
Shut Down the System
10. Shut down all subsystems.
11. From TACL, stop the OSM Service Connection:
> SCF ABORT PROCESS $zzkrn.#osm-cimom
12. From TACL, issue this command to purge the IAREPO file:
> PURGE $SYSTEM.ZSERVICE.IAREPO
13. If any scripts, such as SCFCSTM or TACLCSTM, reference the system name, alter them to
include the new system name.
14. Verify that the $SYSTEM alternate key file does not point to the system name. From a TACL
prompt, issue this command:
-> FUP INFO $SYSTEM.SYSTEM.USERID,DETAIL
