[L]ist Nodes, [M]odify Nodes, [A]nalyze, [H]elp, [P]roceed, [Q]uit: l
Output Type - a[B]breviated, [A]ll, [C]ancel:
• The a[B]breviated output is similar to the following. Nodes with the same role
assignments are condensed into one line item.
Node: n16 location: Level 1 Switch 172.20.65.1, Port 42
CURRENT HEAD NODE
Roles assigned: compute console_network disk_io external
management_hub management_server resource_management
External Ethernet name: penguin.southpole.com
ipaddr: 192.0.2.0 netmask: 255.255.252.0 gateway: 192.0.2.51
The following nodes are configured with the common role "compute":
n[11-15]
• [A]ll output is similar to the following and displays specific information about the
head node and each client node. Be aware that output can be lengthy on a system with
a large number of nodes. For example, the output for a 500-node system with 495
compute-only nodes results in approximately 1500 lines of output.

NOTE: If the hardware configuration contains HP server blades and enclosures, the
node's enclosure location is provided:
Node: n11 location: Enclosure n-enc00110a881340
Roles assigned: compute
3. Do the following to determine whether you have to modify the default role assignments:
a. See Appendix F (page 209) for a description of the default role assignments based on
system size.
Read about the special considerations regarding the default role assignments to
determine if the role assignments are suitable for your environment. If you do not
modify the role assignments, the system will be configured with the default assignments.
b. If you are configuring services for improved availability, read the information in
Table 1-2 (page 32) to ensure that you assign the appropriate roles to the nodes in
availability sets so that service failover can occur.
