The cinder.volume.drivers.dell_emc.vnx.replication Module¶

class ReplicationAdapter(client=None, config=None)¶

Bases: object

add_volumes_to_group_replication(group, volumes)¶

append_replication_stats(stats)¶

build_mirror_view(configuration, failover=True)¶

Builds a mirror view operation class.

Parameters:	configuration – driver configuration failover – True if from primary to configured array, False if from configured array to primary.

cleanup_lun_replication(volume)¶

create_group_replication(group)¶

delete_group_replication(group)¶

disable_replication(context, group, volumes)¶

Disable the group replication.

Note: This will not disable the replication on individual LUNs.

do_setup()¶

enable_replication(context, group, volumes)¶

Enable the group replication.

Note: this will not interfere with the replication on individual LUNs.

failover_host(context, volumes, secondary_backend_id, groups)¶

Fails over the volume back and forth.

Driver needs to update following info for failed-over volume: 1. provider_location: update serial number and lun id 2. replication_status: new status for replication-enabled volume

failover_replication(context, group, volumes, secondary_backend_id)¶

“Fail-over the consistent mirror group.

Note:

VNX supports fail over all the mirrors in a group as a whole, no need to handle each mirror one by one.

get_replication_error_status(context, groups)¶

The failover only happens manually, no need to update the status.

remove_volumes_from_group_replication(group, volumes)¶

setup_lun_replication(volume, primary_lun_id)¶

Setup replication for LUN, this only happens in primary system.

validate_backend_id(backend_id)¶
