G.3 Modifying a Node
From the command-line menu of the cluster_config utility, enter the letter m to modify node
role assignments and Ethernet connections:
[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: m
You are prompted to supply the node name of the node you want to modify. All operations you
perform from this point are performed on this node until you specify a different node name.
Please enter node name or [C]ancel: n15
Current Node: n15
[E]xternal Network Configuration, [R]oles, [H]elp, [B]ack:
At this point you have the following options:
• Enter the letter e to add, remove, or modify an external Ethernet connection on any node.
This process is described in “Configuring an Ethernet Connection” (page 224).
• Enter the letter r and proceed to “Modifying Node Role Assignments” (page 225) to modify
node role assignments.
• Enter the letter b to return to the previous menu.
G.4 Configuring an Ethernet Connection
You must add an external Ethernet network connection to any node that is assigned with the
nis_server or the external role.
Follow this procedure to add, change, or delete an Ethernet connection on any node:
1. From the command-line menu of the cluster_config utility, enter the letter m :
[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: m
2. Supply the node name of the node you want to modify. All operations you perform from
this point are performed on this node until you specify a different node name.
Please enter node name or [C]ancel: n15
Current Node: n15
3. At the following prompt, enter the letter e:
[E]xternal Network Configuration, [R]oles, [H]elp, [B]ack: e
4. To add a network Ethernet connection to a node to connect the node directly to the public
network, enter the letter e again and, when prompted, supply the required information:
[E]dit Network Settings, [D]elete Network Settings, [H]elp, [B]ack: e
Hostname []: penguin2.example.com
IP address []: 192.0.2.4
Netmask [255.255.252.0]: 255.255.255.0
You have the option to provide an IPv6 address for
the external Ethernet connection.
You can enter an IPv6 address, enter '[]' to delete the value shown,
or press the Enter key to accept the value shown.
IPv6 address (optional) []:
Gateway IP address [ ]: 192.0.2.51
You have the option to override the system default MTU value.
You can enter 9000 to enable jumbo frames,
enter '[]' to delete the value shown and use the system default,
or press the Enter key to accept the value shown.
MTU value (optional) []:
[E]dit Network Settings, [D]elete Network Settings, [H]elp, [B]ack:
