ibm.spectrum_virtualize.ibm_svc_manage_migration module – This module manages volume migration between clusters on IBM Spectrum Virtualize family storage systems

Note

This module is part of the ibm.spectrum_virtualize collection (version 1.12.0).

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 ibm.spectrum\_virtualize.

To use it in a playbook, specify: ibm.spectrum_virtualize.ibm_svc_manage_migration.

New in ibm.spectrum_virtualize 1.6.0

Synopsis

  • Ansible interface to manage the migration commands.

Parameters

Parameter

Comments

clustername

string / required

The hostname or management IP of the Spectrum Virtualize storage system.

domain

string

Domain for the Spectrum Virtualize storage system.

Valid when hostname is used for the parameter clustername.

log_path

string

Path of debug log file.

new_pool

string

added in ibm.spectrum_virtualize 1.11.0

Specifies the pool on which the volume has to be migrated.

Valid only when type_of_migration=across_pools.

password

string

REST API password for the Spectrum Virtualize storage system.

The parameters username and password are required if not using token to authenticate a user on the local system.

relationship_name

string

Name of the migration relationship. Required when state=initiate or state=switch.

remote_cluster

string

Specifies the name of the remote cluster.

Required when state=initiate.

remote_password

string

REST API password for the partner Spectrum Virtualize storage system.

The parameters remote_username and remote_password are required if not using remote_token to authenticate a user on the partner system.

Valid when state=initiate.

remote_pool

string

Specifies the pool on which the volume on Partner Spectrum Virtualize storage system should get created.

Required when state=initiate.

remote_token

string

The authentication token to verify a user on the partner Spectrum Virtualize storage system.

To generate a token, use the ibm_svc_auth module. Valid when state=initiate.

remote_username

string

REST API username for the partner Spectrum Virtualize storage system.

The parameters remote_username and remote_password are required if not using remote_token to authenticate a user on the partner system.

Valid when state=initiate.

remote_validate_certs

boolean

Validates certification for partner Spectrum Virtualize storage system.

Valid when state=initiate.

Choices:

  • false ← (default)

  • true

replicate_hosts

boolean

Replicates the hosts mapped to a source volume on the source system, to the target system, and maps the hosts to the target volume. The user can use ibm_svc_host and ibm_svc_vol_map modules to create and map hosts to the target volume for an existing migration relationship.

Valid when state=initiate.

Choices:

  • false ← (default)

  • true

source_volume

string

Specifies the name of the existing source volume to be used in migration.

Required when state=initiate or state=cleanup or type_of_migration=across_pools.

state

string

Specifies the different states of the migration process when type_of_migration=across_clusters.

initiate, creates a volume on remote cluster; optionally used to replicate hosts, and to create and start a migration relationship.

switch, switches the migration relationship direction allowing write access on the target volume.

cleanup, deletes the source volume and migration relationship after a ‘switch’.

Choices:

  • "initiate"

  • "switch"

  • "cleanup"

target_volume

string

Specifies the name of the volume to be created on the target system.

Required when state=initiate.

token

string

The authentication token to verify a user on the Spectrum Virtualize storage system.

To generate a token, use the ibm_svc_auth module.

type_of_migration

string

added in ibm.spectrum_virtualize 1.11.0

Specifies the type of migration whether it is migration across pools or migration across clusters

Choices:

  • "across_pools"

  • "across_clusters" ← (default)

username

string

REST API username for the Spectrum Virtualize storage system.

The parameters username and password are required if not using token to authenticate a user on the local system.

validate_certs

boolean

Validates certification.

Choices:

  • false ← (default)

  • true

Notes

Note

  • This module supports check_mode.

  • This module supports both volume migration across pools and volume migration across clusters.

  • In case, user does not specify type_of_migration, the module shall proceed with migration across clusters by default.

  • In case of type_of_migration=across_pools, the only parameters allowed are new_pool and source_volume along with cluster credentials.
