Ticket 06 – Identifying Orphaned Objects

Title: “What are these unused pools and nodes?”

Ticket Description

During a routine review of the CentralRegion-bigip-01 configuration, operations suspects there may be unused (orphaned) objects left over from previous testing or decommissioned applications.

You have been asked to identify any orphaned pools and nodes on CentralRegion-bigip-01 so they can be documented and, if appropriate, cleaned up later.

Context

Device Name: CentralRegion-bigip-01

These objects are believed not to be referenced by any active virtual servers.

Tasks

Use the AI Assistant located at the top of the home screen and enter the following prompt:

Show all pools and nodes on CentralRegion-bigip-01, and indicate which ones are not referenced by any virtual server.

From the returned information and the TMUI on CentralRegion-bigip-01:

  • Navigate to: Local Traffic >> Pools >> Pool List

    Confirm whether bruce_wayne and oliver_twist appear in the configuration.

  • Verify whether either pool is assigned as a default pool (or referenced in a policy) on any virtual server.

Next, navigate to: Local Traffic >> Nodes >> Node List

  • Confirm whether clark_kent and harry_potter appear in the node list.
  • Verify whether any pool members reference these nodes, or whether they are completely unused.

Summarize which of the above pools and nodes are truly orphaned (that is, not referenced by any virtual server or pool). Do not delete anything as part of this exercise. The goal is only to locate and document orphaned objects.

Deliverables

Briefly answer the following:

  • How many pools are on CentralRegion-bigip-01?
  • How many of those pools are not referenced by any Virtual Server?

Review the following for additional information and trends:

  • A clear list of which objects are confirmed to be orphaned on CentralRegion-bigip-01

Hints

  • A pool is considered orphaned if no virtual server uses it as a default pool and it is not referenced by policies or iRules.
  • A node is considered orphaned if no pool member references it.
  • Comparing object references (who uses what) is a key step when cleaning up legacy configuration.

Suspected orphaned objects:

  • Pools: bruce_wayne, oliver_twist
  • Nodes: clark_kent, harry_potter

This concludes Ticket 06.
