VOLUMES = 'volumes'¶

snapshot_create(otype, typename, ouri, snaplabel, inactive, sync, readonly=False, synctimeout=0)¶

New snapshot is created, for a given volume.

Parameters:

otype – block type should be provided typename – either volume or consistency-groups should be provided ouri – uri of volume snaplabel – name of the snapshot inactive – if true, the snapshot will not activate the synchronization between source and target volumes sync – synchronous request synctimeout – Query for task status for ‘synctimeout’ secs. If the task doesn’t complete in synctimeout secs, an exception is thrown

snapshot_delete(storageres_type, storageres_typename, resource_uri, name, sync, synctimeout=0)¶

snapshot_delete_uri(otype, resource_uri, suri, sync, synctimeout=0)¶

Delete a snapshot by uri.

Parameters:	otype – block resource_uri – uri of the source resource suri – Uri of the Snapshot sync – To perform operation synchronously synctimeout – Query for task status for ‘synctimeout’ secs. If the task doesn’t complete in synctimeout secs, an exception is thrown

snapshot_list_uri(otype, otypename, ouri)¶

Makes REST API call to list snapshots under a volume.

Parameters:	otype – block otypename – either volume or consistency-group should be provided ouri – uri of volume or consistency-group
Returns:	list of snapshots

snapshot_query(storageres_type, storageres_typename, resuri, snapshot_name)¶

snapshot_show_uri(otype, resource_uri, suri)¶

Retrieves snapshot details based on snapshot Name or Label.

Parameters:	otype – block suri – uri of the Snapshot. resource_uri – uri of the source resource
Returns:	Snapshot details in JSON response payload

storage_resource_query(storageres_type, volume_name, cg_name, project, tenant)¶
