## Synopsis

- Create or remove volumes (standard and thin) for NetApp E/EF-series storage arrays.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
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/devmgr/v2
api_username string / required |  | The username to authenticate with the SANtricity Web Services Proxy or Embedded Web Services API.

cache_without_batteries
boolean
added in 2.9

Choices:
- no ←
- yes

Indicates whether caching should be used without battery backup.
Warning, cache_without_batteries==true and the storage system looses power and there is no battery backup, data will be lost!

data_assurance_enabled
boolean

Choices:
- no ←
- yes

Determines whether data assurance (DA) should be enabled for the volume
Only available when creating a new volume and on a storage pool with drives supporting the DA capability.

initialization_timeout integer added in 2.9 |  | Duration in seconds before the wait_for_initialization operation will terminate. wait_for_initialization==True to have any effect on module's operations.

metadata
dictionary
added in 2.8

Dictionary containing meta data for the use, user, location, etc of the volume (dictionary is arbitrarily defined for whatever the user deems useful)
When workload_name exists on the storage array but the metadata is different then the workload definition will be updated. (Changes will update all associated volumes!)
workload_name must be specified when metadata are defined.

name - / required |  | The name of the volume to manage.

owning_controller
-
added in 2.9

Choices:
- A
- B

Specifies which controller will be the primary owner of the volume
Not specifying will allow the controller to choose ownership.

read_ahead_enable
boolean
added in 2.8

Choices:
- no
- yes ←

Indicates whether or not automatic cache read-ahead is enabled.
This option has no effect on thinly provisioned volumes since the architecture for thin volumes cannot benefit from read ahead caching.

read_cache_enable
boolean
added in 2.8

Choices:
- no
- yes ←

Indicates whether read caching should be enabled for the volume.

segment_size_kb
-

Default:
"128"

Segment size of the volume
All values are in kibibytes.
Some common choices include '8', '16', '32', '64', '128', '256', and '512' but options are system dependent.
Retrieve the definitive system list from netapp_e_facts under segment_sizes.
When the storage pool is a raidDiskPool then the segment size must be 128kb.
Segment size migrations are not allowed in this module

size - / required |  | Required only when state=='present'. Size of the volume in size_unit. Size of the virtual volume in the case of a thin volume in size_unit. Maximum virtual volume size of a thin provisioned volume is 256tb; however other OS-level restrictions may exist.

size_unit
-

Choices:
- bytes
- b
- kb
- mb
- gb ←
- tb
- pb
- eb
- zb
- yb

The unit used to interpret the size parameter

ssd_cache_enabled
boolean

Choices:
- no ←
- yes

Whether an existing SSD cache should be enabled on the volume (fails if no SSD cache defined)
The default value is to ignore existing SSD cache setting.

ssid string | Default: 1 | The ID of the array to manage. This value must be unique for each array.

state
- / required

Choices:
- present
- absent

Whether the specified volume should exist

storage_pool_name - |  | Required only when requested state=='present'. Name of the storage pool wherein the volume should reside.

thin_provision
boolean

Choices:
- no ←
- yes

Whether the volume should be thin provisioned.
Thin volumes can only be created when raid_level=="raidDiskPool".
Generally, use of thin-provisioning is not recommended due to performance impacts.

thin_volume_expansion_policy
-
added in 2.8

Choices:
- automatic ←
- manual

This is the thin volume expansion policy.
When thin_volume_expansion_policy=="automatic" and thin_volume_growth_alert_threshold is exceed the thin_volume_max_repo_size will be automatically expanded.
When thin_volume_expansion_policy=="manual" and thin_volume_growth_alert_threshold is exceeded the storage system will wait for manual intervention.
The thin volume_expansion policy can not be modified on existing thin volumes in this module.
Generally speaking you should almost always use thin_volume_expansion_policy=="automatic.

thin_volume_growth_alert_threshold - added in 2.8 | Default: 95 | This is the thin provision repository utilization threshold (in percent). When the percentage of used storage of the maximum repository size exceeds this value then a alert will be issued and the thin_volume_expansion_policy will be executed. Values must be between or equal to 10 and 99.

thin_volume_max_repo_size
-

Default:
"same as size (in size_unit)"

This is the maximum amount the thin volume repository will be allowed to grow.
Only has significance when thin_volume_expansion_policy=="automatic".
When the percentage thin_volume_repo_size of thin_volume_max_repo_size exceeds thin_volume_growth_alert_threshold then a warning will be issued and the storage array will execute the thin_volume_expansion_policy policy.
Expansion operations when thin_volume_expansion_policy=="automatic" will increase the maximum repository size.

thin_volume_repo_size
-

This value (in size_unit) sets the allocated space for the thin provisioned repository.
Initial value must between or equal to 4gb and 256gb in increments of 4gb.
During expansion operations the increase must be between or equal to 4gb and 256gb in increments of 4gb.
This option has no effect during expansion if thin_volume_expansion_policy=="automatic".
Generally speaking you should almost always use thin_volume_expansion_policy=="automatic.

validate_certs
boolean

Choices:
- no
- yes ←

Should https certificates be validated?

wait_for_initialization
boolean
added in 2.8

Choices:
- no ←
- yes

Forces the module to wait for expansion operations to complete before continuing.

workload_name
-
added in 2.8

Label for the workload defined by the metadata.
When workload_name and metadata are specified then the defined workload will be added to the storage array.
When workload_name exists on the storage array but the metadata is different then the workload definition will be updated. (Changes will update all associated volumes!)
Existing workloads can be retrieved using netapp_e_facts.

write_cache_enable
boolean
added in 2.8

Choices:
- no
- yes ←

Indicates whether write-back caching should be enabled for the volume.

## Notes

Note

- 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.

- netapp_e_storage_system may be utilized for configuring the systems managed by a WSP instance.
