Node with hostname.

Hello

I am facing the following issue while creating new pool

0107003a:3: Pool member node (/Common/172.16.2.5) and existing node (/Common/apache1.test.com) cannot use the same IP Address (172.16.2.5).

I agreed the node is already existing with host name that is the reason behind this. But my challenge we have more than 2000 nodes some of them are created with host name and some of them are with ip hence we are always facing the above issue.

Is there any way to override this. or is there any way to convert all host name based nodes in to ip?

    Hi,

    this is not possible to rename nodes without removing it and creating it again with the expected name.

    With 2000 nodes, it may be long to browse node list and that's why you enter again the node IP address instead of selecting it in previously created nodes...

    with such a long list of nodes, you may manage your F5 with partition to create pools, nodes and virtual servers classified by projects and not listing other projects nodes and pools.

    To rename all nodes, you may try to list all nodes with command:

    list ltm nodes one-line

    Then, create for each node the delete and the create commands:

    For the node testnode IP 1.2.3.4, :

delete ltm node testnode
create ltm node 1.2.3.4 { address 1.2.3.4 }

    Execute it in transaction:

    create cli transaction
delete ltm node testnode
create ltm node 1.2.3.4 { address 1.2.3.4 }
submit cli transaction

    it will execute both commands and will submit it only if both finished successfully.
