description:
- Create, destroy, or update volumes on ElementSW
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.
- It accepts volume_name or volume_id
required: true
account_id:
description:
- Account ID for the owner of this volume.
- It accepts Account_id or Account_name
required: true
enable512e:
description:
- Required when C(state=present)
- Should the volume provide 512-byte sector emulation?
type: bool
aliases:
- 512emulation
qos:
description: Initial quality of service settings for this volume. Configure as dict in playbooks.
attributes:
description: A YAML dictionary of attributes that you would like to apply on this volume.
size:
description:
- The size of the volume in (size_unit).
- Required when C(state = present).
size_unit:
description:
- The unit used to interpret the size parameter.
choices: ['bytes', 'b', 'kb', 'mb', 'gb', 'tb', 'pb', 'eb', 'zb', 'yb']
default: 'gb'
access:
description:
- Access allowed for the volume.
- 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.
choices: ['readOnly', 'readWrite', 'locked', 'replicationTarget']
