Changing System Name, System Number, or Time
Attributes
Changing System Name, System Number, or
Time Attributes
After the first system load, use SCF to modify the values for the following system
attributes:
•
SYSTEM_NAME
•
SYSTEM_NUMBER
•
TIME_ZONE_OFFSET
•
DAYLIGHT_SAVINGS_TIME
See the SCF Reference Manual for the Kernel Subsystem.
Because the attributes that change the system name and Expand system (node)
number are stored in a SEEPROM in the enclosure backplane, changes to them
require a system reset and reload to take effect. If you do not modify these attribute
values, they default to the values shipped by HP:
Changing the System Topology
If you want or need to change the topology of a system, you must shut down the
system. The NonStop S-Series System Expansion and Reduction Guide gives
complete information about the procedures necessary to reconfigure your system
offline.
Changing the CONFTEXT File
Any changes to the CONFTEXT file take effect after the next system load. If you want
to modify the CONFTEXT file, see the System Generation Manual for G-Series RVUs.
The modified CONFTEXT file is used by DSM/SCM when generating a new operating
system image. See the DSM/SCM User’s Guide.
SYSTEM_NAME \NONAME
SYSTEM_NUMBER 254
TIME_ZONE_OFFSET 0:00 (London)
DAYLIGHT_SAVINGS_TIME NONE
Caution. Changing the system name or Expand system (node) number is intended for a newly
installed system. If you change the system name or system number on an existing system and
are running complex applications like NonStop SQL/MP, HP NonStop Transaction
Management Facility (TMF), or HP NonStop Open System Services (OSS), you must
reconfigure the applications and take additional precautions to avoid losing data.
