Additional nodes for Node Group

[vasanthapr335]

Dear Experts ,

                            I am using NNM 9.20 . I have nodes for which i need to craete a node group . I cant do it using their host names since all are of different format . Even i cant do by IP Address .

  I want to assign nodes to a node group using additional nodes option of node group .

  Since the no of node is 900+ , is there any command to add bulk nodes to a node group  ?

     Kindly suggest .

thanks.

Vasan,

In case, i would suggest to us the nnmloadnodegroups.ovpl — script to load Node Group definitions from a comma-separated values (CSV) file.

You will need to create the Syntax of Comma-Separated File (csv file)

YOu could find those info from the reference page document which already attached on this.

Recommended read: Syntax of Comma-Separated File

Any Additional Nodes specified (column 6) are always included in the Node Group, regardless of any filters

Column 6(F) : Additional Nodes Optional. Specify a list of specific node hostnames you want added to this Node Group, separated by a semicolon ";" (After importing, these specifications appear on the Additional Nodes tab of the Node Group form.) The hostnames you provide must be the current value of the fully-qualified, case-sensitive Hostname attribute as it appears on the Node form. For example hostname1.x.y.z;hostname2.x.y.z;hostname3.x.y.z

Dear trinhdong ,

                                     Thanks for concern .

  I have used nnmloadnodegroup.ovpl command to create a new node group and assign additional node to it .I sucessfully done it .

As i said i need to add 900 + nodes to that node group  and  i dont think this way will not help me to do that.

    Even i cant use additional filter . It failed to filter them .

       So i got a solution is usage of  additional filers  and tenantName like tenatname .

But  during addition of nodes we directly added nodes without tenants .

    So all nodes tenant name is Default Tenant .

     Is there any command which will allow me to change nodes tenant name  in bulk ?

  Please correct me if my idea is wrong ...

thanks ,

Hi ,

         I have used

C:\>nnmsecurity.ovpl -assignNodeToTenant -tenant tenantname -node node_name

And it worked . Is there any issues if change tenant name to custom name ?

Please suggest .

thanks

Vasan,

What i meant is used the additional filers on the given nnmloadnodegroup.ovpl , you could see the Additional Nodes Optional supported by this command. Specify a list of specific node hostnames you want added to this Node Group, separated by a semicolon ";". More optional, Specify a list of Security-Group, Tenant propreties that you want to add to this node-group.....

After importing, these specifications appear on the Additional Nodes tab of the Node Group form.

I also prefered to use the Additional Nodes tab on the Node Group form to add a list of specific nodes ( ranges of IP addresses) to this Node Group. However, this way will directly add nodes with default tenant.

NNMi provides the helpful command line tool, nnmsecurity.ovpl

C:\>nnmsecurity.ovpl -assignNodeToTenant -tenant tenantname -node node_name

Tenant may also be refered to as a customer or an organization. Tenants are not Security Groups but they can be used in conjunction with Security Groups. A Tenant can have an Initial Discovery Security Group assigned to it. When discovering a node into NNMi using a seed, you can specify the Tenant assignment. This means that if a node is discovered with a Tenant assigned, it can automatically be assigned into a Security Group. Thus, there is never a risk of accidentally having nodes visible to operators that are not supposed to see those nodes.
