Changing System Names and Numbers
Step 1: Save the current configuration file
As a precaution, use the SCF SAVE command to save the current configuration files
on the duplicate nodes. For example, the following command saves the configuration
file at $SYSTEM.ZSYSCONF.CONF0101:
-> SAVE CONFIG 1.1
The SCF SAVE command is described in detail in the SCF Reference Manual for G-
Series RVUs.
Step 2: Isolate the duplicate nodes
You must isolate all nodes with the duplicate names or numbers from the network by
stopping all connections between these nodes and those adjacent to them using one
of the following Expand subsystem SCF commands:
ABORT LINE $device_name
ABORT PATH $device_name
Step 3: View the current system name and number
View the settings for the system name and number (shown below in bold type) using
the Kernel subsystem SCF INFO SUBSYS command. The following is an example of a
display produced by the SCF INFO SUBSYS command.
The SCF INFO SUBSYS command is described in detail in the SCF Reference Manual
for the Kernel Subsystem.
Note. Use the ABORT PATH command for multi-line paths. This command affects the
specified line and its associated path logical device; it does not affect other lines in the multi-
line path.
