netapp.ontap.na_ontap_qos_policy_group module – NetApp ONTAP manage policy group in Quality of Service.

Note

This module is part of the netapp.ontap collection (version 22.0.1).

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. You need further requirements to be able to use this module, see Requirements for details.

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

New in netapp.ontap 2.8.0

Synopsis

  • Create, destroy, modify, or rename QoS policy group on NetApp ONTAP.

Requirements

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

  • Ansible 2.9 or later - 2.12 or later is recommended.

  • Python3 - 3.9 or later is recommended.

  • When using ZAPI, 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

Parameters

Parameter

Comments

adaptive_qos_options

dictionary

added in netapp.ontap 21.19.0

Adaptive QoS policy-groups define measurable service level objectives (SLOs) that adjust based on the storage object used space and the storage object allocated space.

Only supported with REST.

absolute_min_iops

integer / required

Specifies the absolute minimum IOPS that is used as an override when the expected_iops is less than this value.

These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

expected_iops

integer / required

Expected IOPS. Specifies the minimum expected IOPS per TB allocated based on the storage object allocated size.

These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

peak_iops

integer / required

Peak IOPS. Specifies the maximum possible IOPS per TB allocated based on the storage object allocated size or the storage object used size.

cert_filepath

string

added in netapp.ontap 20.6.0

path to SSL client cert file (.pem).

not supported with python 2.6.

feature_flags

dictionary

added in netapp.ontap 20.5.0

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.

fixed_qos_options

dictionary

added in netapp.ontap 21.19.0

Set Minimum and Maximum throughput defined by this policy.

Only supported with REST.

Required one of throughtput options when creating qos_policy.

capacity_shared

boolean

Whether the SLOs of the policy group are shared between the workloads or if the SLOs are applied separately to each workload.

Default value is False if not used in creating qos policy.

Choices:

  • false

  • true

max_throughput_iops

integer

Maximum throughput defined by this policy. It is specified in terms of IOPS.

0 means no maximum throughput is enforced.

max_throughput_mbps

integer

Maximum throughput defined by this policy. It is specified in terms of Mbps.

0 means no maximum throughput is enforced.

min_throughput_iops

integer

Minimum throughput defined by this policy. It is specified in terms of IOPS.

0 means no minimum throughput is enforced.

These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

min_throughput_mbps

integer

Minimum throughput defined by this policy. It is specified in terms of Mbps.

0 means no minimum throughput is enforced.

Requires ONTAP 9.8 or later, and REST support.

force

boolean

Setting to ‘true’ forces the deletion of the workloads associated with the policy group along with the policy group.

Not supported with REST.

Choices:

  • false

  • true

force_ontap_version

string

added in netapp.ontap 21.23.0

Override the cluster ONTAP version when using REST.

The behavior is undefined if the version does not match the target cluster.

This is provided as a work-around when the cluster version cannot be read because of permission issues. See https://github.com/ansible-collections/netapp.ontap/wiki/Known-issues.

This should be in the form 9.10 or 9.10.1 with each element being an integer number.

When use_rest is set to auto, this may force a switch to ZAPI based on the version and platform capabilities.

Ignored with ZAPI.

from_name

string

Name of the existing policy group to be renamed to name.

hostname

string / required

The hostname or IP address of the ONTAP instance.

http_port

integer

Override the default port (80 or 443) with this port

https

boolean

Enable and disable https.

Ignored when using REST as only https is supported.

Ignored when using SSL certificate authentication as it requires SSL.

Choices:

  • false ← (default)

  • true

is_shared

boolean

added in netapp.ontap 20.12.0

Whether the SLOs of the policy group are shared between the workloads or if the SLOs are applied separately to each workload.

Not supported with REST, use fixed_qos_options.

Choices:

  • false

  • true

key_filepath

string

added in netapp.ontap 20.6.0

path to SSL client key file.

max_throughput

string

Maximum throughput defined by this policy.

Not supported with REST, use fixed_qos_options.

min_throughput

string

Minimum throughput defined by this policy.

Not supported with REST, use fixed_qos_options.

name

string / required

The name of the policy group to manage.

ontapi

integer

The ontap api version to use

password

aliases: pass

string

Password for the specified user.

state

string

Whether the specified policy group should exist or not.

Choices:

  • "present" ← (default)

  • "absent"

use_rest

string

Whether to use REST or ZAPI.

always – will always use the REST API if the module supports REST. A warning is issued if the module does not support REST. An error is issued if a module option is not supported in REST.

never – will always use ZAPI if the module supports ZAPI. An error may be issued if a REST option is not supported in ZAPI.

auto – will try to use the REST API if the module supports REST and modules options are supported. Reverts to ZAPI otherwise.

Default: "auto"

username

aliases: user

string

This can be a Cluster-scoped or SVM-scoped account, depending on whether a Cluster-level or SVM-level API is required.

For more information, please read the documentation https://mysupport.netapp.com/NOW/download/software/nmsdk/9.4/.

Two authentication methods are supported

  1. basic authentication, using username and password,

  2. SSL certificate authentication, using a ssl client cert file, and optionally a private key file.

To use a certificate, the certificate must have been installed in the ONTAP cluster, and cert authentication must have been enabled.

validate_certs

boolean

If set to no, the SSL certificates will not be validated.

This should only set to False used on personally controlled sites using self-signed certificates.

Choices:

  • false

  • true ← (default)

vserver

string / required

Name of the vserver to use.

Notes

Note

  • The modules prefixed with na_ontap are built to support the ONTAP storage platform.

  • https is enabled by default and recommended. To enable http on the cluster you must run the following commands ‘set -privilege advanced;’ ‘system services web modify -http-enabled true;’
