Announcing PowerVC 1.4.4 Fix Pack 2

Hi there! We now bring you a few more exciting features and fixes in our signature virtualization product – PowerVC. Today we’re officially releasing the 1.4.4 fix pack 2, which contains the following updates:

Firmware support
PowerVC 1.4.4.2 will support upcoming firmware 950.

RHEL Support
PowerVC 1.4.4.2 supports RHEL 8.2 as guest operating system for LE.

DRO - Formula update

While calculating CPU utilization of a host, PowerVC will add CPU utilization used by all virtual machines on this host as following:

If virtual machine is sharing processors (pool) then do not consider idle time of processors.
If virtual machine has dedicated processors, then do not consider donated times.

VLAN allocation algorithm change
PowerVC load balances VLAN configuration across multiple VEAs during deploy for optimal network performance of VM. This feature is disabled by default and can be enabled via a config option through powervc-config CLI.

Optimized the time taken for RMC state moving to ‘OK’
PowerVC now detects RMC state of virtual machine much faster.

AIX®LKU support for Hitachi storage
PowerVC version 1.4.4 fix pack 2 comes with AIX LKU support for Hitachi storage.

PowerMax support for Initiator port groups
Initiator port groups allow usage of specific set of ports per volume attachment. This would mean different volumes attached to a VM can be configured to use different paths. This capability is now extended to support EMC PowerMax storage.
Limitation of sharing volumes (PowerMax) is NOW removed - volumes with SLO/Workload can now be shared between VMs.

Live capture of virtual machines is now possible when using tape drives
You can live capture virtual machines even when using tape drives. PowerVC version 1.4.4 fix pack 2 can now skip tape drives on a virtual machine and the capture proceeds with the rest of the volumes allowing live capture of virtual machines.

Fixes
Although a little less exciting than new support, a fix pack needs to have some fixes too. These are the APAR fixes included with this fix pack:

IT32148: DRP based registration fails to validate license for compression.

IT32184: PowerVC does not support NVME ports.

IT32200: PowerVC saves VM reference code instead of metadata when 'createserver' API is used.

IT32378: VM deploy with HPE3par and multipath setup doesn't show 4 paths.

IT32661: Updated FlashCopy rates are not reflecting while volume flash copy.

IT32698: PowerVC failed to migrate VMs when zone-by-stg-provider is set to True.

IT32888: Performance issue when volume tracker generates unnecessary health events.

IT32889: PowerVC failed to delete cloned data volumes.

IT32946: PowerVC cleans unused VLANs.

IT33127: PowerVC fails to discover CISCO switches if at least one of them has any issue.

IT33212: PowerVC is impacted by an OpenStack Nova vulnerability which could leak console auth tokens into log files (CVE-2015-9543).

IT33269: PowerVC allocates vLAN using packing algorithm resulting in performance issues.

IT33297: Performance optimization for volume operations on Hitachi backed storage.

IT33448: VM deploy failure due to HTTP connection issues.

IT33451: Time improvement for VM to come to 'OK' Health State in UI.

IT33484: Ref_Code support for VMs with AIX and Linux OS.

IT33501: Enablement of AIX LKU for disks with Hitachi backed storage.

IT33613: PowerVC allocates capacity for snapshot volumes when using thin provisioning policy.

IT33716: PowerVC fix to make clone API calls asynchronous.

IT33948: Unable to attach volumes to a VM.

IT33949: Powervc-diag fails to collect logs.
