How You Change Remote Node Definitions
The procedure you use for changing an existing remote node definition depends on whether the vnode name for the definition is unique among the node definitions for the installation.
If the vnode name is unique (that is, associated with only one node definition), overwrite the existing definition. For instructions, see
Overwrite an Existing Definition.
If the vnode name is not unique (that is, associated with more than one node definition), you must delete the incorrect definition and set up the new definition. For instructions, see
Delete Old and Add New Definition.
Overwrite an Existing Definition
Use this procedure to change a node definition only if the vnode name associated with that definition is not associated with any other node definitions within the local set of remote node definitions.
To overwrite an existing definition
1. Start netu by entering netu at the operating system prompt.
The main menu appears.
2. Select N (Modify Node Entry) from the menu.
The following prompt appears:
Enter the operation (add, merge, del, show, exit):
3. Enter add. (Type a instead of add.)
Prompts appear.
4. Answer the prompts using the values of the new, correct node definition.
The utility overwrites the existing node definition with the values that you have just supplied and displays the following prompt:
Enter operation (add, merge, del, show, exit):
5. Continue with other node definition tasks or Enter to the netu menu by choosing exit.
Delete Old and Add New Definition
Use this procedure when there are two or more remote node definitions (at the same node) that are associated with the vnode name belonging to the definition that you want to change.
When the merge option has been used to set up several node definitions that use the same vnode name, you must be very careful when changing one of these definitions. You
cannot overwrite the incorrect definition using the add option as in
Overwrite an Existing Definition. If you try to do this, netu overwrites all of the definitions that have the specified vnode name, effectively deleting them all and leaving you with only the definition you have just added.
To safely change a node definition that has a vnode name in common with other node definitions, you must delete the old definition and use merge to add the new definition.
To delete an old definition and add a new one
1. Start netu by entering netu at the operating system prompt.
The main menu appears.
2. Select N (Modify Node Entry) from the menu.
The following prompt appears:
Enter operation (add, merge, del, show, exit):
3. Enter del. (Enter d instead of del.)
4. Answer the prompts that appear with the values from the definition you want to change.
When all the prompts are answered, netu deletes the node definition that has the values that you have just supplied and Enters you to the prompt:
Enter operation (add, merge, del, show, exit):
5. Enter merge. (Enter m instead of merge.)
6. Answer the prompts that appear with the values for the correct definition.
The utility adds a node definition with the values that you have just supplied and displays the following prompt:
Enter operation (add, merge, del, show, exit):
7. Continue with node definition tasks or Enter to the main netu menu by choosing exit.
