dellemc.powerflex.mdm_cluster module – Manage MDM cluster on Dell PowerFlex

Note

This module is part of the dellemc.powerflex collection (version 1.9.0).

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

To use it in a playbook, specify: dellemc.powerflex.mdm_cluster.

New in dellemc.powerflex 1.3.0

Synopsis

• Managing MDM cluster and MDMs on PowerFlex storage system includes adding/removing standby MDM, modify MDM name and virtual interface.

• It also includes getting details of MDM cluster, modify MDM cluster ownership, cluster mode, and performance profile.

Requirements

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

• A Dell PowerFlex storage system version 3.5 or later.

• Ansible-core 2.13 or later.

• PyPowerFlex 1.8.0.

• Python 3.9, 3.10 or 3.11.

Parameters

Parameter	Comments
clear_interfaces boolean	Clear all virtual IP interfaces. The clear_interfaces is mutually exclusive with virtual_ip_interfaces. Choices: false true
cluster_mode string	Mode of the cluster. Choices: "OneNode" "ThreeNodes" "FiveNodes"
hostname aliases: gateway_host string / required	IP or FQDN of the PowerFlex host.
is_primary boolean	Set is_primary as true to change MDM cluster ownership from the current master MDM to different MDM. Set is_primary as false, will return MDM cluster details. New owner MDM must be an MDM with a manager role. Choices: false true

timeout integer	Time after which connection will get terminated. It is to be mentioned in seconds. Default: 120
username string / required	The username of the PowerFlex host.
validate_certs aliases: verifycert boolean	Boolean variable to specify whether or not to validate SSL certificate. true - Indicates that the SSL certificate should be verified. false - Indicates that the SSL certificate should not be verified. Choices: false true ← (default)
virtual_ip_interfaces list / elements=string	List of interfaces to be used for virtual IPs. The order of interfaces must be matched with virtual IPs assigned to the cluster. Interfaces of the primary and secondary type MDMs are allowed to modify. The virtual_ip_interfaces is mutually exclusive with clear_interfaces.

Notes

Note

• Parameters mdm_name or mdm_id are mandatory for rename and modify virtual IP interfaces.

• Parameters mdm_name or mdm_id are not required while modifying performance profile.

• For change MDM cluster ownership operation, only changed as true will be returned and for idempotency case MDM cluster details will be returned.

• Reinstall all SDC after changing ownership to some newly added MDM.

• To add manager standby MDM, MDM package must be installed with manager role.

• The check_mode is supported.

• The modules present in the collection named as ‘dellemc.powerflex’ are built to support the Dell PowerFlex storage platform.
