We are officially releasing PowerVC, which is bundled with many new enhancements and support features in addition to those that were available in the recent major release PowerVC 2.0.2.

Release highlights

PowerVC contains the following updates:

Direct install or upgrade to

You can now directly install PowerVC unlike earlier releases where you had to first install the major version and then update to the available fix pack version of PowerVC. Similarly, if you have any previous version of PowerVC installed, take a backup, copy the backup file to a custom location, and then uninstall the existing version. Reboot the system and install or upgrade to PowerVC

Backup and restore on multinode

With PowerVC, you can perform restore directly on multinode (three nodes) from PowerVC version 2.0.1 to For details, see Upgrading to PowerVC 2.0.2 or

HMC host scaling with additional Compute plane node

Starting PowerVC version, Compute plane nodes are introduced to share the compute services load and allow managing more HMC managed hosts. For details, see Compute plane node and HMC host scaling.

Multinode on HMC

HMC managed hosts can be added to both single node setup as well as three node setup of PowerVC cluster. This ensures the Nova compute process for the host is configured in an Active-passive mode and monitored by Pacemaker.

Infoblox integration

You can manage the DNS records in Infoblox through PowerVC GUI. For details, see Automatically update DNS records.

Multinode support on SLES ppc64le

Installation is supported on SLES ppc64le for both single node and multinode environments.

Scheduled tasks

If you are assigned to self-service user role, you can schedule virtual machine operations such as start, stop, and restart of VM(s).
