Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO mean the same thing :-)
There are two partially overlapping notions is HPOM: node groups and layout groups. Node groups are older concept (layout groups were introduced in version 8 of HPOM ).
There can be special node groups that are not intended for use with responsibilities. These node groups are flagged as Invisible Node Groups and will not appear in any responsibility matrix. That can make responsibilities matrix more compact.
There are two main areas of node group usage in HPOM :
Each node node must appear in at least one Node Group. A typical HPOM configuration uses one node group per operating system, something like Linux, Solaris, HP-UX, AIX, Windows, etc.
A node can be assigned to multiple node groups. When you do not want the node in a particular node group you need to de-assign it ( but not to delete the node from the node group: big mistake).
A node in HPOM can be assigned to multiple node groups.
In order to see anything concerning a managed node, including messages about or from the node, it must be in the Node Hierarchy and at least one Node Group. In this sense node group is a logical group of nodes managed by particular operator(s).
Node groups should not be mixed with different newer concept introduced in version 8 of HPOM called layout groups. They are similar to node groups but are used mostly as the way organize the nodes for operation Java GUI. At the same time they can be used to perform operations on a group of nodes that constitute layout group. In this second role they are quite similar to node groups.
You can either use GUI or command opcnode -assign_node to assign note to a node group.
After you have created a node hierarchy, HPOM provides the opcnode command-line tool, which allows applying actions to all the nodes contained in the parent group simultaneously. For example, to assign a policy to a series of nodes, specify the parent node group of the nodes you want to assign the policies to and the policy you want to assign:
opcnode -assign_pol pol_name= <policy_name> pol_type=<policy_type> version=<policy_version> \
HPOM automatically assigns the policy to the node group including all nodes contained in that group.
Actions You Can Apply to All Nodes
You can apply the following actions to a managed node, the HPOM node hierarchy, and the HPOM node bank:
Modify a node group by using the opcnode command-line tool.
Start up HPOM applications by using Customized Startup .
View the messages of selected node symbols.
Start and stop agent services.
Distribute software, configurations, and so on.
Actions You Cannot Apply to All Nodes. You cannot apply any of the following actions to a managed node, the HPOM node hierarchy bank, or the HPOM node bank:
Add or modify applications.
The All Node Groups page displays a list of the nodes groups deployed to the currently selected HPOM for UNIX management server. The information in the All Node Groups page is displayed in a table with the following information; note that you can click the Name column title to reorganise list of managed node groups in ascending or descending order.
Click the actions button () to display a list of the actions you can perform on the node groups in the list; click the browse button () to display a list of the node-group-configuration details that you can browse.
|All||Check boxes to allow you to select all or individual node groups on which you want to perform an action using the "Choose an action..." drop-down menu at the bottom of the table, for example: "Move to layout group...", "Assign to Node Group...", and "Delete from Node Group...".|
|Label||Indicates the name assigned to the node-group icon in the GUI (OM for Unix only)|
|Name||Shows the name of the managed node group. Click a node-group name to see more detailed information about the selected node group, including the nodes the node group contains. Click one of the icons next to the node-group name to display menus that allow you to view more information about the node group or perform an action on the node group. For more information about the browse and actions menus and the options they contain, see the tables below.|
|Node||The number of nodes in the currently selected node group.|
|Description||A brief explanation of the contents of the selected node group.|
|Visible||Indicates if the node-group icon is visible in the GUI or hidden (OM for Unix only)|
|Policies||Indicates if the node group has policies assigned|
There is a possibility to push policies assigned to a node group to a single node using command line. This is very convenient option for testing.

Implementation: HPOM 8.30 on HP-UX (PA) 11.23
To Quote the HPOM Online documentation: "You can use the Add Node Hierarchy Bank Window to add or modify node hierarchies. To assign nodes or other node hierarchies to a node hierarchy, you can simply use OVO's drag and drop mechanism."
Now its the second sentence I'm interested in.
It does not seem possible to have a node in more than one layout group per Hierarchy. However you can create multiple Hierarchies with the same nodes in - how can these be nested as indicated by the quote above? Whenever I try Drag'nDrop it will not let me (tried copy and paste etc)
I'm trying to do this to enable operators to better use the Java console, sometimes they want to be able to choose Nodes by Datacentre, or Domain, or OS, or Application/Server role etc. But if a server can only be in one place on the Hierarchy how can they be in multiple groups?
Thanks for any help
I checked out assigning an OVO Operator multiple Hierarchies but this seems to be a non starter (and pointless if nesting works)
A node will exist exactly once in each layout group hierarchy. If you don't place it somewhere in the hierarchy, it will be put into HoldingArea automatically.
That's the way it works.
You can create "Nodebanks" and nodes can be assigned to multiple Nodebanks, but not multiple "Layout Groups". The Node Hierarchy exists for "Layout Groups", and not "Nodebanks", so you can only have a node in one.
Bah - Seems like an irritating limitation. I suppose one would need something like the Configuration Value Pack to be able to achieve what I'm after?
