Changing System Names and Numbers
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 these 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. This is an example of a display
produced by the SCF INFO SUBSYS command.
The SCF INFO SUBSYS command is described in det
ail in the SCF Reference Manual
for the Kernel Subsystem.
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
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.
