check_for_export(context, volume_id)

Make sure volume is exported.

check_for_setup_error()
create_cgsnapshot(context, cgsnapshot)

Creates a cgsnapshot.

create_cloned_volume(volume, src_vref)

Creates a cloned volume.

create_consistencygroup(context, group)

Creates a consistencygroup.

create_export(context, volume)

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

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)

Deletes a cgsnapshot.

delete_consistencygroup(context, group)

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.

get_volume_stats(refresh=False)

Get volume stats.

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

initialize_connection(*args, **kwargs)
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.

existing_ref:{
‘id’:lun_id

}

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.

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

Convert the volume to be of the new type.

terminate_connection(*args, **kwargs)
update_volume_stats()

Retrieve stats info from volume group.
