Adrian Likins 2c7563b9bb Add modules for NetApp SANtricity storage platform (#2929)
The modules prefixed with netapp_e* are built to support the
SANtricity storage platform.

The modules provide idempotent provisioning for volume groups, disk
pools, standard volumes, thin volumes, LUN mapping, hosts, host groups
(clusters), volume snapshots, consistency groups, and asynchronous
mirroring.

They require the SANtricity WebServices Proxy.
The WebServices Proxy is free software available at
the NetApp Software Download site:

   http://mysupport.netapp.com/NOW/download/software/eseries_webservices/1.40.X000.0009/

Starting with the E2800 platform (11.30 OS), the modules will work
directly with the storage array.  Starting with this platform, REST API
requests are handled directly on the box.  This array can still be
managed by proxy for large scale deployments.

module: netapp_e_amg_sync
short_description: Conduct synchronization actions on asynchronous member groups.
description:
- Allows for the initialization, suspension and resumption of an asynchronous mirror group's synchronization for NetApp E-series storage arrays.
version_added: '2.2'
author: Kevin Hulquest (@hulquest)
options:
api_username:
required: true
description:
- The username to authenticate with the SANtricity WebServices Proxy or embedded REST API.
api_password:
required: true
description:
- The password to authenticate with the SANtricity WebServices Proxy or embedded REST API.
api_url:
required: true
description:
- The url to the SANtricity WebServices Proxy or embedded REST API.
example:
- https://prod-1.wahoo.acme.com/devmgr/v2
validate_certs:
required: false
default: true
description:
- Should https certificates be validated?
ssid:
description:
- The ID of the storage array containing the AMG you wish to target
name:
description:
- The name of the async mirror group you wish to target
required: yes
state:
description:
- The synchronization action you'd like to take.
- If C(running) then it will begin syncing if there is no active sync or will resume a suspended sync. If there is already a sync in progress, it will return with an OK status.
- If C(suspended) it will suspend any ongoing sync action, but return OK if there is no active sync or if the sync is already suspended
choices:
- running
- suspended
required: yes
delete_recovery_point:
description:
- Indicates whether the failures point can be deleted on the secondary if necessary to achieve the synchronization.
- If true, and if the amount of unsynchronized data exceeds the CoW repository capacity on the secondary for any member volume, the last failures point will be deleted and synchronization will continue.
- If false, the synchronization will be suspended if the amount of unsynchronized data exceeds the CoW Repository capacity on the secondary and the failures point will be preserved.
- "NOTE: This only has impact for newly launched syncs."
choices:
- yes
- no
default: no
