RHBA-2020:0764 - Bug Fix Advisory

Topic

Updated OpenStack Block Storage packages that resolve various issues are
now available for Red Hat OpenStack Platform 13.0 (Queens) for RHEL 7.

Description

Red Hat OpenStack Platform provides the facilities for building, deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware. This advisory includes
packages for:

• OpenStack Block Storage service

OpenStack Block Storage (cinder) manages block storage mounting and the
presentation of such mounted block storage to instances. The back-end
physical storage can consist of local disks, Fiber Channel, iSCSI, and/or
NFS mounts attached to Compute nodes. In addition, Block Storage supports
volume backups, and snapshots for temporary save and restore operations.
Programmatic management is available through the Block Storage service's
API.

Changes to the openstack-cinder component:

• Before this update, zone creation that used a second or later target nsp from a 3PAR back end caused the creation of bootable volumes to fail intermittently. This is because the HPE 3PAR client code used the first target nsp to form the initiator target map, in the case of a system that was connected to HPE 3PAR via FC with multipath disabled.

With this update, you can specify the target nsp in the 3PAR backend section of the `cinder.conf` file in the following way:
hpe3par_target_nsp = <n:s:p>
This means that the target information comes from `cinder.conf`, the initiator target map is created from the respective wwn information, and the creation of bootable volumes is successful. (BZ#1768832)

Solution

Before applying this update, ensure all previously released errata relevant
to your system have been applied.
