Describe the issue:
  During an installation of disconnected OCS cluster based on OCP
  documentation[2], there is a section *3.9.3. Pruning an index image*[3] which
  contain following step:
    iii. Inspect the packages.out file and identify which package names from
    this list you want to keep in your pruned index.

  For OCS version 4.8 and older, the required package is ocs-operator (and
  prospectively local-storage-operator), which is quite clear from the name,
  but for OCS/ODF 4.9 the required packages are at least following 3:
    noobaa-operator,
    ocs-operator,
    odf-operator
  and it might not be fully clear, that all those packages are required and
  when are required some other packages like odf-multicluster-orchestrator.

Describe the task you were trying to accomplish:
  Install Disconnected OCS/ODF 4.9 cluster.

Suggestions for improvement:
  Describe required and optional packages in Chapter 9. Disconnected
  environment[1] of the Planning your deployment documentation.
