Changing System Names and Numbers
Step 4: Change the system name and/or system number
You must change the system name and/or system number of one of the duplicate
nodes. To change the system name or number, use the Kernel subsystem SCF ALTER
command. For example:
ALTER, SYSTEM_NAME \EAST
ALTER, SYSTEM_NUMBER 44
If you are changing both the system name and system number, you can more
efficiently use system resources (because these attributes are stored in the server
hardware) by grouping them into one command rather than by entering each
separately; for example:
ALTER, SYSTEM_NAME \EAST, SYSTEM_NUMBER 44
The ALTER command is described in detail in the SCF Reference Manual for the
Kernel Subsystem.
Step 5: Confirm the changes
Confirm the changes with another INFO command (changes are shown below in
boldface type). The INFO command displays both the current and the changed values,
which take effect at the next system load.
Caution. Be sure that you enter the ALTER command correctly. SCF has no knowledge of a
system name or number that has not been brought up (in an Expand network) since the most
recent load of the local system.
Caution. If the system name and number are to be changed, they should be done at the same
time with a single system load.
