module: sf_volume_manager
short_description: Manage SolidFire volumes
extends_documentation_fragment:
- netapp.solidfire
version_added: '2.3'
author: Sumit Kumar (sumit4@netapp.com)
description:
- Create, destroy, or update volumes on SolidFire
options:
state:
description:
- Whether the specified volume should exist or not.
required: true
choices: ['present', 'absent']
name:
description:
- The name of the volume to manage.
required: true
account_id:
description:
- Account ID for the owner of this volume.
required: true
512emulation:
description:
- Should the volume provide 512-byte sector emulation?
- Required when C(state=present)
required: false
qos:
description: Initial quality of service settings for this volume.
required: false
default: None
attributes:
description: A YAML dictionary of attributes that you would like to apply on this volume.
required: false
default: None
volume_id:
description:
- The ID of the volume to manage or update.
- In order to create multiple volumes with the same name, but different volume_ids, please declare the I(volume_id)
parameter with an arbitary value. However, the specified volume_id will not be assigned to the newly created
volume (since it's an auto-generated property).
required: false
default: None
size:
description:
- The size of the volume in (size_unit).
- Required when C(state = present).
required: false
size_unit:
description:
- The unit used to interpret the size parameter.
required: false
choices: ['bytes', 'b', 'kb', 'mb', 'gb', 'tb', 'pb', 'eb', 'zb', 'yb']
default: 'gb'
access:
description:
- Access allowed for the volume.
required: false
choices: ['readOnly', 'readWrite', 'locked', 'replicationTarget']
access_type_description:
- readOnly: Only read operations are allowed.
- readWrite: Reads and writes are allowed.
- locked: No reads or writes are allowed.
- replicationTarget: Identify a volume as the target volume for a paired set of volumes. If the volume is not paired, the access status is locked.
- If unspecified, the access settings of the clone will be the same as the source.
default: None
