module: sf_check_connections
deprecated:
  removed_in: "2.11"
  why: This Module has been replaced
  alternative: please use M(na_elementsw_check_connections)
short_description: Check connectivity to MVIP and SVIP.
extends_documentation_fragment:
    - netapp.solidfire
version_added: '2.3'
author: Sumit Kumar (@timuster) <sumit4@netapp.com>
description:
- Used to test the management connection to the cluster.
- The test pings the MVIP and SVIP, and executes a simple API method to verify connectivity.

options:

  skip:
    description:
    - Skip checking connection to SVIP or MVIP.
    choices: ['svip', 'mvip']

  mvip:
    description:
    - Optionally, use to test connection of a different MVIP.
    - This is not needed to test the connection to the target cluster.

  svip:
    description:
    - Optionally, use to test connection of a different SVIP.
    - This is not needed to test the connection to the target cluster.
