15.4.1
^^^^^^


New Features
************

* This PowerMax driver moves the legacy shared volume from the
  masking view structure in Ocata and prior releases (when SMI-S was
  supported) to staging masking view(s) in Pike and later releases
  (U4P REST). In Ocata, the live migration process shared the storage
  group, containing the volume, among the different compute nodes. In
  Pike, we changed the masking view structure to facilitate a cleaner
  live migration process where only the intended volume is migrated
  without exposing other volumes in the storage group. The staging
  storage group and masking views facilitate a seamless live migration
  operation in upgraded releases.


Known Issues
************

* PowerMax driver - Disabling inuse storage assisted migration to a
  metro or asynchronous replicated volume type as this operation will
  not facilitate FC scanning or iSCSI login of the target array.


Bug Fixes
*********

* Fixed bug #1859652
  (https://bugs.launchpad.net/cinder/+bug/1859652) to allow retyping
  an attached volume to SolidFire.

* Bug #1887885 (https://bugs.launchpad.net/cinder/+bug/1887885): In
  NEC driver, fix a snapshot detach error.

* Bug #1887908 (https://bugs.launchpad.net/cinder/+bug/1887908)： In
  NEC driver, fix live-migration failure with FC.

* RBD driver Bug #1898918
  (https://bugs.launchpad.net/cinder/+bug/1898918): Fix thread block
  caused by the flatten operation during cloning a volume. Now the
  flatten operation is executed in a different thread.

* Bug #1904440 (https://bugs.launchpad.net/cinder/+bug/1904440):
  When an iSCSI/FC encrypted volume was cloned, the rekey operation
  would stamp the wrong encryption key on the newly cloned volume.
  This resulted in a volume that could not be attached.  It does not
  present a security problem.

* Bug #1884268 (https://bugs.launchpad.net/cinder/+bug/1884268):
  Fixed issue where non-admin users could not show a volume transfer
  by name.
