module: nxos_smu
extends_documentation_fragment: nxos
version_added: "2.2"
short_description: Perform SMUs on Cisco NX-OS devices.
description:
    - Perform software maintenance upgrades (SMUs) on Cisco NX-OS devices.
author: Gabriele Gerbino (@GGabriele)
notes:
    - Tested against NXOSv 7.3.(0)D1(1) on VIRL
    - The module can only activate and commit a package,
      not remove or deactivate it.
    - Use C(transport=nxapi) to avoid connection timeout
options:
    pkg:
        description:
            - Name of the remote package.
        required: true
    file_system:
        description:
            - The remote file system of the device. If omitted,
              devices that support a file_system parameter will use
              their default values.
        required: false
        default: null
