At the main menu of the cluster_config utility, enter the letter M to modify a node. [L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: M |
Enter the node name 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: Adding an Ethernet Connection | |
To add a network Ethernet connection to a node to connect the node directly to your public network, enter the letter E at the following prompt: [E]xternal Network Configuration, [R]oles, [H]elp, [B]ack: E |
Enter the letter E again at the following prompt to create a new Ethernet connection or modify an existing connection: [E]dit Network Settings, [D]elete Network Settings, [H]elp, [B]ack: E
hostname: penguin2.southpole.com
IP Address: 192.0.2.4
Netmask: 255.255.255.0
Gateway IP Address: 192.0.2.51
[E]dit Network Settings, [D]elete Network Settings, [H]elp, [B]ack: |
You must define an external Ethernet network connection to any node that is assigned with the nis_server or external role. Enter the letter B when you have completed your task to go back to the previous menu. Modifying Node Role Assignments | |
The cluster configuration menu provides the ability for you to assign roles to specific nodes. See “Role Definitions” for detailed definitions of all node roles and the services they provide. Enter the letter R at the following prompt to modify the default node role assignments: [E]xternal Network Configuration, [R]oles, [H]elp, [B]ack: R |
The following submenu is displayed: [1] : compute
[2] : disk_io
[3] : external
[4] : login
[5] : management_hub
[6] : management_server
[7] : nis_server
[8] : resource_management
Current Node: n15
Current Assigned Roles: compute disk_io
Enter the number corresponding to the role or roles you want to assign to this
node. Use a space-separated list to specify multiple roles, for example, 1 3 5.
Or, enter 'c' to [C]ancel. |
Assume you want to add a login role to node n15. Not only do you enter the number 4, you must also enter the numbers 1 and 2 to retain the current compute and disk_io roles on node n15. Basically, you have to supply every role that you want to assign to the node. Thus, your entry looks like this: Enter the number corresponding to the role or roles you want to assign to this
node. Use a space-separated list to specify multiple roles, for example, 1 3 5.
Or, enter 'c' to [C]ancel. 1 2 4
Roles to be assigned: compute disk_io login
[R]eassign Roles, [O]k, [C]ancel : |
At this point you have the following options: Enter the letter O to accept the role assignments you just made. Enter the letter R to start the assignment process again. The Reassign Roles option does not apply the role assignments, it simply allows you to go back to the list of roles and make adjustments to the role assignments. Enter the letter C to cancel the operation and make no changes to the currently assigned roles.
