In a flexible management environment, you can create, modify,
delete, and view groups of nodes. Groups of nodes make job submission
simpler because you can submit a job for a group of nodes instead
of a entering multiple node names for a job submission.
Before you begin
Before you can add a node to a group of nodes, you must
have registered at least one node with the job manager.
About this task
Groups of nodes are particularly useful if you submit
multiple jobs to the same set of nodes.
The first time you
access the Groups of nodes collection panel, no groups of nodes are
listed. You must create at least one group. You must then enter parameters
for the Find option to obtain a list of groups of nodes based on the
parameter information that you provide. The next time you select , a list of groups of nodes are displayed based on the
parameters you last specified on the Find option for this job manager
administrative console panel. You can then optionally modify the Find
option criteria to display a different set of groups of nodes. After
at least one group of nodes is displayed, you can administer the groups
of nodes by doing such tasks as adding and removing members for node
groups, or deleting node groups.
Procedure
- Create a group of nodes.
- Click in the job manager administrative
console navigation.
- Click New.
- Enter the name of the group of nodes.
- Optionally enter a description.
- Optionally add members to or remove members from the
group of nodes.
Members are nodes. You can add members
to the group or delete members from the group now or later. You can
use the Add option, the Find option, or both options to add the members.
Follow the steps on adding
to or removing members from a group of nodes.
- Click Apply to save the changes,
and then click OK to return to the collection
page.
- Optionally use the Find option to display groups of nodes.
If no groups of nodes are displayed, you must use the Find
option to display groups of nodes based on the parameter information
that you enter.
- Click in the job manager administrative
console navigation.
- Specify a valid operator and a text string.
- Click Find.
- Optionally add or remove the members in a group of node.
You can add and remove members from the group of nodes. Members
are nodes.
- Click in the job manager administrative
console navigation.

- To use the Add option, type the name of the node in the Member list
box, and then click Add.
- Continue to type the name of a node, and then click Add until
you have added all the members.
- To use the Find option, click Find.
- Enter criteria for the Find option by adding text for one or more
options. For example, specify the node name as test* or test*a.
- After getting the list of nodes in the Chosen nodes list,
click OK to return the list to the Groups of
nodes panel.
You can change the find criteria, and select the Find option
multiple times to create the list you want.
- To remove a node, select the node, and click Remove.

Results
Depending on the tasks that you completed, you might have
created a group of nodes, used the Find option to display groups of
nodes, added or deleted members in the group of node, or deleted groups
of nodes.
What to do next
You can continue to administer groups of nodes and do
other job management tasks such as view nodes, submit jobs, and view
node resources.
