done by the cluster_config command will fail to properly export the
/hptc_cluster directory from the head node, which will cause a failure.
2. Enter the following comm and to apply the default configuration, change default node role
assignments, or m odify netw ork Ethernet interfaces on any node except the head node:
# ./cluster_config
The following op tio ns are displ ayed:
[L]ist Nodes, [M]odify Nodes, [H]elp, [P]roceed, [Q]uit:
To learn about the function of these optio ns, enter the letter h to d isplay a description of
each option; entries are not case sensitive:
[L]ist Nodes, [M]odify Nodes, [H]elp, [P]roceed, [Q]uit: h
This utility enables you to modify node role assignments
and define external network connections on nodes other than the
head node.
Valid commands are:
L - Lists discovered nodes with current location, assigned roles,
and external network connections
M - Modifies nodes with the Modify Node submenu
H - Displays this help message
P - Proceeds to the next cluster configuration step
Q - Quits this utility leaving the cluster unmodified
[L]ist Nodes, [M]odify Nodes, [H]elp, [P]roceed, [Q]uit:
3. Enter the letter l to list the current, default configur ation; then enter the letter b or the
letter a to view an abbreviated or full version of th e output:

The following nodes are configured with the common roles "compute"
and "nat_client":

roles assigned: compute nat_client
4. Do one of the following:
a. If you are not satisfied with the default system configuration, and you want to change
default role assignmen ts or create an external Ethernet connection on a node other
than the head node, see Appendix I.
b. If yo u are satisfied with the defaul t system configuration, continue to step 5.
