Synopsis
--------

Managing device on PowerFlex storage system includes adding new device, getting details of device, and removing a device.

  current_pathname (optional, str, None)
    Full path of the device to be added.

    Required while adding a device.


  device_name (optional, str, None)
    Device name.

    Mutually exclusive with *device_id*.


  device_id (optional, str, None)
    Device ID.

    Mutually exclusive with *device_name*.


  sds_name (optional, str, None)
    The name of the SDS.

    Required while adding a device.

    Mutually exclusive with *sds_id*.


  sds_id (optional, str, None)

    State of the device.


  force (optional, bool, False)
    Using the Force flag to add a device.

    Use this flag, to overwrite existing data on the device.

    Use this flag with caution, because all data on the device will be destroyed.

    IP or FQDN of the PowerFlex host.


  username (True, str, None)
    The username of the PowerFlex host.


  password (True, str, None)
    The password of the PowerFlex host.


  validate_certs (optional, bool, True)
    Boolean variable to specify whether or not to validate SSL certificate.

    ``true`` - Indicates that the SSL certificate should be verified.

    Port number through which communication happens with PowerFlex host.


  timeout (False, int, 120)
    Time after which connection will get terminated.

    It is to be mentioned in seconds.





Notes
-----

.. note::
   - The value for device_id is generated only after successful addition of the device.
   - To uniquely identify a device, either *device_id* can be passed or one of *current_pathname* or *device_name* must be passed with *sds_id* or *sds_name*.
   - It is recommended to install Rfcache driver for SSD device on SDS in order to add it to an acceleration pool.
   - The *check_mode* is not supported.
   - The modules present in the collection named as 'dellemc.powerflex' are built to support the Dell PowerFlex storage platform.
