module: snapshot
short_description: Manage snapshots on the Unity storage system
description:
- Managing snapshots on the Unity storage system includes create snapshot,
  delete snapshot, update snapshot, get snapshot, map host and unmap host.
version_added: '1.1.0'

extends_documentation_fragment:
  - dellemc.unity.unity

author:
- P Srinivas Rao (@srinivas-rao5) <ansible.team@dell.com>
options:
  snapshot_name:
    description:
    - The name of the snapshot.
    - Mandatory parameter for creating a snapshot.
    - For all other operations either I(snapshot_name) or I(snapshot_id) is
      required.
    type: str
  vol_name:
    description:
    - The name of the volume for which snapshot is created.
    - For creation of a snapshot either I(vol_name) or I(cg_name) is required.
    - Not required for other operations.
    type: str
  cg_name:
    description:
    - The name of the Consistency Group for which snapshot is created.
    - For creation of a snapshot either I(vol_name) or I(cg_name) is required.
    - Not required for other operations.
    type: str
  snapshot_id:
    description:
    - The id of the snapshot.
    - For all operations other than creation either I(snapshot_name) or
      I(snapshot_id) is required.
    type: str
  auto_delete:
    description:
    - This option specifies whether the snapshot is auto deleted or not.
    - If set to C(true), snapshot will expire based on the pool auto deletion
      policy.
    - If set to (false), snapshot will not be auto deleted
      based on the pool auto deletion policy.
    - Option I(auto_delete) can not be set to C(true), if I(expiry_time) is specified.
    - If during creation neither I(auto_delete) nor I(expiry_time) is mentioned
      then snapshot will be created keeping I(auto_delete) as C(true).
    - Once the I(expiry_time) is set then snapshot cannot be assigned
      to the auto delete policy.
    type: bool
  expiry_time:
    description:
    - This option is for specifying the date and time after which the
      snapshot will expire.
    - The time is to be mentioned in UTC timezone.
    - The format is "MM/DD/YYYY HH:MM". Year must be in 4 digits.
    type: str
  description:
    description:
    - The additional information about the snapshot can be provided using
      this option.
    type: str
  new_snapshot_name:
    description:
    - New name for the snapshot.
    type: str
  state:
    description:
    - The I(state) option is used to mention the existence of
      the snapshot.
    type: str
    required: true
    choices: [ 'absent', 'present' ]
  host_name:
    description:
    - The name of the host.
    - Either I(host_name) or I(host_id) is required to map or unmap a snapshot from
      a host.
    - Snapshot can be attached to multiple hosts.
    type: str
  host_id:
    description:
    - The id of the host.
    - Either I(host_name) or I(host_id) is required to map or unmap a snapshot from
      a host.
    - Snapshot can be attached to multiple hosts.
    type: str
  host_state:
    description:
    - The I(host_state) option is used to mention the existence of the host
      for snapshot.
    - It is required when a snapshot is mapped or unmapped from host.
    type: str
    choices: ['mapped', 'unmapped']

notes:
  - The I(check_mode) is not supported.
