The cinder.volume.drivers.pure
Module¶
Volume driver for Pure Storage FlashArray storage system.
This driver requires Purity version 4.0.0 or later.
-
class
PureBaseVolumeDriver
(*args, **kwargs)¶ Bases:
cinder.volume.drivers.san.san.SanDriver
Performs volume management on Pure Storage FlashArray.

do_setup
(context)¶ Performs driver initialization steps that could raise exceptions.

get_volume_stats
(*args, **kwargs)¶
-
manage_existing
(*args, **kwargs)¶
-
manage_existing_get_size
(*args, **kwargs)¶
-
manage_existing_snapshot
(snapshot, existing_ref)¶ Brings an existing backend storage object under Cinder management.
We expect a snapshot name in the existing_ref that matches one in Purity.
-
manage_existing_snapshot_get_size
(snapshot, existing_ref)¶ Return size of snapshot to be managed by manage_existing.
We expect a snapshot name in the existing_ref that matches one in Purity.
-
retype
(context, volume, new_type, diff, host)¶ Retype from one volume type to another on the same backend.
For a Pure Array there is currently no differentiation between types of volumes. This means that changing from one type to another on the same array should be a no-op.
-
terminate_connection
(*args, **kwargs)¶
-
unmanage
(*args, **kwargs)¶
-
unmanage_snapshot
(snapshot)¶ Removes the specified snapshot from Cinder management.
Does not delete the underlying backend storage object.
We expect a snapshot name in the existing_ref that matches one in Purity.
