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 Jobs > Groups of nodes,
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 Jobs > Groups of nodes 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 Jobs > Groups
of nodes 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 Jobs > Groups
of nodes in the job manager administrative
console navigation.
- Click one of the
names of a group of nodes.
- To
add a node, use the Add option, the Find
option, or both.
- To use the Add option, type the
name of the node in the Member list

- Continue to type the name
of a node, and then click Add until you
have added all the members.

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.

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.
