module: netapp_e_snapshot_volume
short_description: NetApp E-Series manage snapshot volumes.
description:
- Create, update, remove snapshot volumes for NetApp E/EF-Series storage arrays.
author: Kevin Hulquest (@hulquest)
notes:
- Only I(full_threshold) is supported for update operations. If the snapshot volume already exists and the threshold matches, then an C(ok) status
will be returned, no other changes can be made to a pre-existing snapshot volume.
options:
api_username:
required: true
description:
- The username to authenticate with the SANtricity WebServices Proxy or embedded REST API.
api_password:
required: true
description:
- The password to authenticate with the SANtricity WebServices Proxy or embedded REST API.
api_url:
required: true
description:
- The url to the SANtricity WebServices Proxy or embedded REST API.
validate_certs:
required: false
default: true
description:
- Should https certificates be validated?
type: bool
ssid:
description:
- storage array ID
required: True
snapshot_image_id:
required: True
description:
- The identifier of the snapshot image used to create the new snapshot volume.
- "Note: You'll likely want to use the M(netapp_e_facts) module to find the ID of the image you want."
full_threshold:
description:
- The repository utilization warning threshold percentage
default: 85
name:
required: True
description:
- The name you wish to give the snapshot volume
view_mode:
required: True
description:
- The snapshot volume access mode
choices:
- modeUnknown
- readWrite
- readOnly
- __UNDEFINED
repo_percentage:
description:
- The size of the view in relation to the size of the base volume
default: 20
storage_pool_name:
description:
- Name of the storage pool on which to allocate the repository volume.
required: True
state:
description:
- Whether to create or remove the snapshot volume
required: True
choices:
- absent
- present
