Installing a Product Revision
Installing a Product Revision
A product revision, such as an SPR, might include one or more fixes to programs
supplied by HP, or it might contain code that adds new function to an HP software
product. Installing a product revision might or might not require that the system be shut
down. Follow the installation instructions provided with the product revision. The
DSM/SCM User’s Guide describes installing product revisions in detail.
Changing the 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
Refer to 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
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, refer to the System Generation Manual for G-Series
RVUs.
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 such as NonStop SQL/MP, TMF, or HP NonStop Open
System Services (OSS), you must reconfigure the applications and take additional precautions
to avoid losing data.
