module: na_cdot_aggregate

short_description: Manage NetApp cDOT aggregates.
extends_documentation_fragment:
    - netapp.ontap
version_added: '2.3'
author: Sumit Kumar (@timuster) <[email protected]>

deprecated:
  removed_in: '2.11'
  why: Updated modules released with increased functionality
  alternative: Use M(na_ontap_aggregate) instead.

description:
- Create or destroy aggregates on NetApp cDOT.

options:

  state:
    required: true
    description:
    - Whether the specified aggregate should exist or not.
    choices: ['present', 'absent']

  name:
    required: true
    description:
    - The name of the aggregate to manage.

  disk_count:
    description:
    - Number of disks to place into the aggregate, including parity disks.
    - The disks in this newly-created aggregate come from the spare disk pool.
    - The smallest disks in this pool join the aggregate first, unless the C(disk-size) argument is provided.
    - Either C(disk-count) or C(disks) must be supplied. Range [0..2^31-1].
    - Required when C(state=present).
