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.
Using TSM instead of OSM
HP Manufacturing sets the initial system configuration so that OSM is enabled on the
system and TSM is disabled. This includes disabling power scrub and processor
alarms by TSM. If you want to use TSM instead of OSM, instructions are available in
“TSM Coexistence and Fallback” in the OSM Migration Guide.
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:
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.
