backup_use_temp_snapshot()

check_for_export(context, volume_id)

Make sure volume is exported.

check_for_setup_error()

create_cgsnapshot(context, cgsnapshot, snapshots)

Creates a cgsnapshot.

create_cloned_volume(volume, src_vref)

Creates a cloned volume.

create_consistencygroup(context, group)

Creates a consistencygroup.

create_consistencygroup_from_src(context, group, volumes, cgsnapshot=None, snapshots=None, source_cg=None, source_vols=None)

Creates a consistency group from source.

create_export(context, volume, connector)

Driver entry point to get the export info for a new volume.

create_export_snapshot(context, snapshot, connector)

Creates a snapshot mount point for snapshot.

create_snapshot(snapshot)

Creates a snapshot.

create_volume(volume)

Creates a volume.

create_volume_from_snapshot(volume, snapshot)

Creates a volume from a snapshot.

delete_cgsnapshot(context, cgsnapshot, snapshots)

Deletes a cgsnapshot.

delete_consistencygroup(context, group, volumes)

Deletes a consistency group.

delete_snapshot(snapshot)

Deletes a snapshot.

delete_volume(volume)

Deletes a volume.

ensure_export(context, volume)

Driver entry point to get the export info for an existing volume.

extend_volume(volume, new_size)

Extend a volume.

failover_host(context, volumes, secondary_id=None)

Failovers volume from primary device to secondary.

get_pool(volume)

Returns the pool name of a volume.

get_volume_stats(refresh=False)

Get volume stats.

If ‘refresh’ is True, run update the stats first.

initialize_connection(*args, **kwargs)

initialize_connection_snapshot(snapshot, connector, **kwargs)

Allows connection to snapshot.

manage_existing(volume, existing_ref)

Manage an existing lun in the array.

The lun should be in a manageable pool backend, otherwise error would return. Rename the backend storage object so that it matches the, volume[‘name’] which is how drivers traditionally map between a cinder volume and the associated backend storage object.

manage_existing_ref:{
    'source-id':<lun id in VNX>
}

or

manage_existing_ref:{
    'source-name':<lun name in VNX>
}

manage_existing_get_size(volume, existing_ref)

Return size of volume to be managed by manage_existing.

migrate_volume(ctxt, volume, host)

Migrate volume via EMC migration functionality.

remove_export(context, volume)

Driver entry point to remove an export for a volume.

remove_export_snapshot(context, snapshot)

Removes snapshot mount point for snapshot.

retype(ctxt, volume, new_type, diff, host)

Convert the volume to be of the new type.

terminate_connection(*args, **kwargs)

terminate_connection_snapshot(snapshot, connector, **kwargs)

Disallows connection to snapshot.

unmanage(volume)

Unmanages a volume.

update_consistencygroup(context, group, add_volumes, remove_volumes)

Updates LUNs in consistency group.

update_migrated_volume(context, volume, new_volume, original_volume_status=None)

Returns model update for migrated volume.

update_volume_stats()

Retrieve stats info from volume group.
