netapp.ontap.na_ontap_flexcache module – NetApp ONTAP FlexCache - create/delete relationship

Note

This module is part of the netapp.ontap collection (version 21.20.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install netapp.ontap.

To use it in a playbook, specify: netapp.ontap.na_ontap_flexcache.

New in version 2.8.0: of netapp.ontap

Synopsis

  • Create/Delete FlexCache volume relationships.

  • This module does not modify an existing FlexCache volume with two exceptions.

  • When using REST, a prepopulate can be started on an exising FlexCache volume.

  • When using REST, the volume can be mounted or unmounted. Set path to ‘’ to unmount it.

  • It is required the volume is mounted to prepopulate it.

  • Some actions are also available through the na_ontap_volume.

Requirements

The below requirements are needed on the host that executes this module.

  • Ansible 2.9

  • Python3 netapp-lib (2018.11.13) or later. Install using ‘pip install netapp-lib’

  • netapp-lib 2020.3.12 is strongly recommended as it provides better error reporting for connection issues.

  • A physical or virtual clustered Data ONTAP system. The modules support Data ONTAP 9.1 and onward.

  • REST support requires ONTAP 9.6 or later.

  • To enable http on the cluster you must run the following commands ‘set -privilege advanced;’ ‘system services web modify -http-enabled true;’

Parameters

Parameter

Comments

aggr_list

aliases: aggregates

list / elements=string

List of aggregates to host target FlexCache volume.

aggr_list_multiplier

aliases: constituents_per_aggregate

integer

Aggregate list repeat count.

REST - Number of FlexCache constituents per aggregate when the aggregates field is mentioned.

auto_provision_as

string

Use this parameter to automatically select existing aggregates for volume provisioning. Eg flexgroup

Note that the fastest aggregate type with at least one aggregate on each node of the cluster will be selected.

Ignored when using REST - omit aggr_list for automatic selection.

path to SSL client cert file (.pem).

not supported with python 2.6.

feature_flags

dictionary

added in 20.5.0 of netapp.ontap

Enable or disable a new feature.

This can be used to enable an experimental feature or disable a new feature that breaks backward compatibility.

Supported keys and values are subject to change without notice. Unknown keys are ignored.

integer

The ontap api version to use

origin_cluster

string

Name of the origin cluster for the FlexCache.

prepopulate

dictionary

added in 21.3.0 of netapp.ontap
