Manage NetApp E-Series manage the storage system’s snapshots.

Parameters 

Parameter	Comments
alert_threshold_pct integer	Percent of filled reserve capacity to issue alert. Default: `75`
api_password string / required	The password to authenticate with the SANtricity Web Services Proxy or Embedded Web Services API.
api_url string / required	The url to the SANtricity Web Services Proxy or Embedded Web Services API. Example https://prod-1.wahoo.acme.com:8443/devmgr/v2
api_username string / required	The username to authenticate with the SANtricity Web Services Proxy or Embedded Web Services API.
group_name string / required	Name of the snapshot consistency group or snapshot volume. Be sure to use different names for snapshot consistency groups and snapshot volumes to avoid name conflicts.
maximum_snapshots integer	Total number of snapshot images to maintain. Default: `32`
pit_description string	Arbitrary description for a consistency group’s snapshot images
pit_name string	Name of a consistency group’s snapshot images.
pit_timestamp string	Snapshot image timestamp in the YYYY-MM-DD HH:MM:SS (AM\|PM) (hours, minutes, seconds, and day-period are optional) Define only as much time as necessary to distinguish the desired snapshot image from the others. 24 hour time will be assumed if day-period indicator (AM, PM) is not specified. The terms latest and oldest may be used to select newest and oldest consistency group images. Mutually exclusive with pit_name or pit_description
preferred_reserve_storage_pool string	Default preferred storage pool or volume group for the reserve capacity volume. The base volume’s storage pool or volume group will be selected by default if not defined. Used to specify storage pool or volume group for both snapshot consistency group volume members and snapshot volumes
reserve_capacity_full_policy string	Policy for full reserve capacity. Purge deletes the oldest snapshot image for the base volume in the consistency group. Reject writes to base volume (keep snapshot images valid). Choices: `"purge"` ← (default) `"reject"`
reserve_capacity_pct integer	Default percentage of base volume capacity to reserve for snapshot copy-on-writes (COW). Used to define reserve capacity for both snapshot consistency group volume members and snapshot volumes. Default: `40`
rollback_backup boolean	Whether a point-in-time snapshot should be taken prior to performing a rollback. Choices: `false` `true` ← (default)
rollback_priority string	Storage system priority given to restoring snapshot point in time. Choices: `"highest"` `"high"` `"medium"` ← (default) `"low"` `"lowest"`
ssid string	The ID of the array to manage. This value must be unique for each array. Default: `"1"`
state string	When state==absent ensures the type has been removed. When state==present ensures the type is available. When state==rollback the consistency group will be rolled back to the point-in-time snapshot images selected by pit_name or pit_timestamp. state==rollback will always return changed since it is not possible to evaluate the current state of the base volume in relation to a snapshot image. Choices: `"absent"` `"present"` ← (default) `"rollback"`
type string	Type of snapshot object to effect. Group indicates a snapshot consistency group; consistency groups may have one or more base volume members which are defined in volumes. Pit indicates a snapshot consistency group point-in-time image(s); a snapshot image will be taken of each base volume when state==present. Warning! When state==absent and type==pit, pit_name or pit_timestamp must be defined and all point-in-time images created prior to the selection will also be deleted. View indicates a consistency group snapshot volume of particular point-in-time image(s); snapshot volumes will be created for each base volume member. Views are created from images from a single point-in-time so once created they cannot be modified. Choices: `"group"` ← (default) `"pit"` `"view"`
validate_certs boolean	Should https certificates be validated? Choices: `false` `true` ← (default)
view_host string	Default host or host group to map snapshot volumes.
view_name string	Consistency group snapshot volume group. Required when state==volume or when ensuring the views absence when state==absent.
view_validate boolean	Default whether snapshop volumes should be validated. Choices: `false` ← (default) `true`
view_writable boolean	Default whether snapshot volumes should be writable. Choices: `false` `true` ← (default)
volumes list / elements=string	Details for each consistency group base volume for defining reserve capacity, preferred reserve capacity storage pool, and snapshot volume options. When state==present and type==group the volume entries will be used to add or remove base volume from a snapshot consistency group. When state==present and type==view the volume entries will be used to select images from a point-in-time for their respective snapshot volumes. If state==present and type==view and volume is not specified then all volumes will be selected with the defaults. Views are created from images from a single point-in-time so once created they cannot be modified. When state==rollback then volumes can be used to specify which base volumes to rollback; otherwise all consistency group volumes will rollback.
preferred_reserve_storage_pool string	Preferred storage pool or volume group for the reserve capacity volume. The base volume’s storage pool or volume group will be selected by default if not defined. Used to specify storage pool or volume group for both snapshot consistency group volume members and snapshot volumes
reserve_capacity_pct integer	Percentage of base volume capacity to reserve for snapshot copy-on-writes (COW). Used to define reserve capacity for both snapshot consistency group volume members and snapshot volumes. Default: `40`
snapshot_volume_host string	Host or host group to map snapshot volume.
snapshot_volume_validate boolean	Whether snapshot volume should be validated which includes both a media scan and parity validation. Choices: `false` ← (default) `true`
snapshot_volume_writable boolean	Whether snapshot volume of base volume images should be writable. Choices: `false` `true` ← (default)
volume string / required	Base volume for consistency group.

Notes 

Note

Key-value pairs are used to keep track of snapshot names and descriptions since the snapshot point-in-time images do have metadata associated with their data structures; therefore, it is necessary to clean out old keys that are no longer associated with an actual image. This cleaning action is performed each time this module is executed.
The E-Series Ansible modules require either an instance of the Web Services Proxy (WSP), to be available to manage the storage-system, or an E-Series storage-system that supports the Embedded Web Services API.
Embedded Web Services is currently available on the E2800, E5700, EF570, and newer hardware models.
