module: na_ontap_aggregate
short_description: Manage NetApp ONTAP aggregates.
extends_documentation_fragment:
- netapp.na_ontap
version_added: '2.6'
author: Sumit Kumar (sumit4@netapp.com), Suhas Bangalore Shekar (bsuhas@netapp.com)
description:
- Create or destroy aggregates on NetApp cDOT.
options:
state:
description:
- Whether the specified aggregate should exist or not.
choices: ['present', 'absent']
default: 'present'
service_state:
description:
- Whether the specified aggregate should be enabled or disabled. Creates aggregate if doesnt exist.
choices: ['online', 'offline']
name:
required: true
description:
- The name of the aggregate to manage.
rename:
description:
- The name of the aggregate that replaces the current name.
nodes:
description:
- List of node for the aggregate
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).
unmount_volumes:
type: bool
description:
- If set to "TRUE", this option specifies that all of the volumes hosted by the given aggregate are to be unmounted
- before the offline operation is executed.
- By default, the system will reject any attempt to offline an aggregate that hosts one or more online volumes.
