Bug fixes
·
Power KVM
Support
·
Add
support for Mellanox SR-IOV NIC CX4 100Gb Glacier
Park and CX4-Lx 25Gb Everglades adapters. Besides offering higher speeds, the
adapters support more logical ports per physical port.
·
Add
maximum capacity for SR-IOV Ethernet logical ports, which puts a cap on how
much of the physical port a logical port can use if it's available. This
provides more control of SR-IOV resource management in cloud environments.
· Add support for SR-IOV adapters in
the NovaLink installer, please see the “Change
Details” section for more info.
·
SR-IOV Installer
Support Limitations
o
IEEE802.3ad/802.1ax
(LACP) is supported if only one logical port is configured for the physical
port. The logical port should be configured with a capacity value of 100%
to prevent configuration of more than one logical port for the physical port.
o Static aggregation or etherchannel configurations are not supported.
o
For network
install, user can’t use the same SR-IOV adapter used for network installation
and configuring the same adapter for the network bridge in the NovaLink installer.
o
In the NovaLink installer, if a physical port is used to configure
the network bridge in SR-IOV shared mode, the port will not be available to use
for vNIC for the client partitions.
·
Issues affecting
HMC Co-Management
o
Prior to
converting a system to a co-managed environment, the user should create a
backup of the profile data (bkprofdata) on the
HMC. This will allow the user to revert to the state prior to
co-management should they desire.
o
Any LPAR that
has not been powered on at least once prior to switching over to a co-managed
mode will need to be re-created.
o
The HMC Enhanced
UI should be used when using the HMC in a co-managed mode. The classic UI
is missing key functionality due to the lack of partition profiles when running
co-managed.
o
NovaLink does not
currently have support for Active Memory Sharing or Hibernation.
·
Issues affecting
full installs (where NovaLink deploys the entire PowerVM stack including the VIOS).
o
When performing
a full install on a new system, if any error occurs before the VIOS server(s)
have been created or installed, you will need to reset the system in order to try again.
Resolution:
If
you encounter an error during the creation or installation of the VIOS
Server(s), you will need to reset your system to the initial factory settings.
This can be done via the ASMI interface or by rebooting the NovaLink
partition and use the 'Reset System' under the 'Choose to repair a system'
option of the NovaLink installation wizard.
o
When performing
a full install on a new system, the IP addresses associated with NovaLink and the VIOS should not use the 192.168.128.1
network (or any superset). NovaLink sets up a
192.68.128.1 network through which to install the VIOS, and allocating that same
network for the external facing IPs will cause the install to fail.
·
Issues affecting
installation in an HMC environment.
o
NovaLink supports
using multipath I/O of physical volumes via redundant VIOSs. However, when using Virtual Optical DVD (vtoptX)
to perform an installation of the NovaLink software,
the same vhostY hosting the NovaLink
LPARs disk must be used if the disk has multiple paths. The following is an example lsmap (on VIOS) output showing vhost0 serving both vtopt0
and vtscsi0 for hdisk1.

Issues
affecting installation in a Software Defined Network mode:
o When installing in Software Defined
Network mode, if a slot assigned to SDN contains disk storage device previously
installed with NovaLink, the installation may fail
with the error message 'No root filesystem is defined'.
Resolution:
If possible assign slots that only have
network device to SDN

PowerVM NovaLink uses versioning
in the form of Version, Release, Mod Level and Fix (VRMF). Example
1.0.0.7
· Version and Release increments have a 3 year software support Lifecycle and follow IBM’s standard software lifecycle (http://www-01.ibm.com/software/support/lifecycle/lc-policy.html).
· Mod Level (third digit) increments have an N-1 support policy. The current available Mod Level and the previous release of a Mod Level are supported.
o For example if 1.0.1.x is currently the latest shipped release, then 1.0.0.x versions are in support. Once 1.0.2.x release is available, support for 1.0.0.x ceases.
· Fix (fourth digit) increments indicate fix and service pack levels for the Mod Level of the release. PowerVM NovaLink uses the Debian method of delivering fixes via a fix repository.
See the Knowledge Center for more information. Errata for service fixes will be posted to Fix Central.
