module: na_cdot_aggregate
short_description: Manage NetApp cDOT aggregates.
extends_documentation_fragment:
- community.general._netapp.ontap
2020-03-09 10:11:07 +01:00
author: Sumit Kumar (@timuster) <sumit4@netapp.com>
deprecated:
removed_in: 2.0.0 # was Ansible 2.11
2020-03-09 10:11:07 +01:00
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).
