SCF Reference Manual for the Kernel Subsystem

Changing the System Name or System Number (J-Series RVUs)
On systems running J-series RVUs, changes to the system name require a shut down of the system
and a subsequent system load.
CAUTION: Changing the system name or system number of an existing system may require
changes in your software application configuration and labeling. Some of these applications are:
• DSM/SCM
• DSM/Tape Catalog (MEDIACOM)
• Enscribe databases
• ODBC/NOS
• Open System Services
• RDF
• ServerNet/FX
• HP Storage Management Facility (SMF)
• HP NonStop SQL/MP
• HP NonStop Transaction Management Facility (TM)
• Application configuration files
• SCFCSTM file
Other applications, as well as application control files such as the Pathway PATHCTL file, might
also be affected and require a change in configuration. Please contact your database administrator
or service provider or software application manual before making system name change.
System Number Change
For information about changing the system number, see the Expand Configuration and Management
Manual.
System Name Change Service Procedures
For complete instructions on changing the system name of a J-series system, refer to the appropriate
service procedure:
• Changing the System Name of a NonStop BladeSystem
• Changing the System Name of a NonStop NS2000 Series System
Changing the System Time Attributes
Changes to them require a system load to take effect.
To reconfigure the DAYLIGHT_SAVING_TIME value, the TIME_ZONE_OFFSET value, or both
values, use this procedure.
1. As a precaution, save the current configuration file with an SCF SAVE command (documented
in the SCF Reference Manual for G-Series RVUs or the SCF Reference Manual for J-Series and
H-Series RVUs). For example, use this command to save the current configuration file in a file
at the location $SYSTEM.ZSYSCONF.CONF0106:
-> SAVE CONFIGURATION 1.6
2. View the current settings for the system time attributes (shown below in bold type) with an SCF
INFO command. The INFO command displays both the current settings and the changed
values of the system name and number attributes, which take effect at the next system load.
-> ASSUME SUBSYS $ZZKRN
-> INFO
