New Features for Users Running HC-5.1.0-P2

  1. Harmony Controller license can now be exported from GLM and imported into Controller without connecting the Controller to Internet or to ELM.
  2. Configuration of Thunders using Device CLI Snippets is available to push configuration to multiple device together.
  3. Direct webhook integration for posting alerts on MS Teams, Slack and Flock. This is in addition to posting webhook to programable interfaces like ServiceNow or a custom server.
  4. Alert definition can now be created based on analytics charts. This eliminates the requirement to go into detailed trigger creation.
  5. Audit logs is now available for user’s ‘write’ activities.
  6. Specific Dashboards are now available for device clusters, Logical clusters, individual devices, CGN scaleout traffic for Provider and Tenant levels as applicable by the administrative scope.
  7. Container Thunder can now be launched in Kubernetes Environment.
  8. Ability to schedule Thunder upgrade from Controller is now available.
  9. ‘Super-Admin’ user can also now login to Operator Console. This allows to reset the password of ‘admin’ user in case ‘admin’ is locked out.
  10. Out of the overall log collecting capacity of a Controller, Super Admin user can now reserve some capacity for future use. They can also allocate dedicated capacity to the providers.
  11. When vThunder instance is launched in AWS or Azure using Harmony Controller, additional IP addresses can be added to the network interface from Harmony Portal itself.
  12. HA Controller deployment is now alos available in public cloud environment and in addition to previously available Data Centre environment.

Deprecation

  • Use of CentOS/RHEL 7.4 and 7.5 for running Harmony Controller is being deprecated. Customers are advised to upgrade the Operating System of the machines running Controller. Next version of Controller may work but will not be supported on CentOS/RHEL 7.4 and 7.5.
  • Direct upgrade support from HC-4.2.1-Px will not be available in next version of Harmony Controller. Customers will be able to upgrade to HC-5.2.0 from HC-4.2.1-Px at any time.

Interface was failing. Thunder Configuration is now available in Harmony
Portal and Access Device function is removed.
GUI-1053
While displaying difference between old and new configuration, the coloring
of config blocks was incorrect. This has been fixed.
HARMONY-9177

All other portions of configuration remain unimpacted.

Known Issues

Item ID
Description
HARMONY-9508
In case of HA Failover, analytics show the new active device status even
for historical data that belongs to old device.
HARMONY-16701
Admin users created on Thunder devices after registering them to
Controller, do not get synchronized with Controller even after
configuration scan. Deregistering Thunder and registering again will fix
the problem. However, mapping Partitions to Tenants may be required again.
HARMONY- 18262
The Thunder cluster launched by Harmony Controller in VMWare vCenter,
AWS or Azure environment only supports cluster type ‘Single’. HA or
VCS clusters needs to be launched manually and attached to Controller.
CM-708
When Thunder configuration with multiple Virtual IP addresses (VIPs) is
created via Harmony Portal and pushed to a Thunder device, analytics
information for all these VIPs does not show up properly. Recommended
is to configure one VIP at a time.
CM-473
When Thunder configuration is modified directly on Thunder, it does not
automatically synchronize with the Controller. Using ‘Scan’ option brings
the configuration to Controller from the device. However, making all
configuration changes from Harmony Portal (Global Object Explorer) is
recommended after registering Thunder to Controller.
GUI-599
Options for scheduled device configuration backup and restore from
Harmony Portal are temporarily reduced and only daily backup is available
for now.
CM-624
GUI-2303
GUI-1995
GUI-2422
In Harmony Portal, Tenant admins can view the devices, partitions
and associated application services that do not belong to them.
Recommended not to onboard application service that require strict
access control.
GUI-1198
When existing configuration is imported or scanned from Thunder device,
some properties may not show up properly in Harmony Portal.
GUI-1302
The Thunder Onboarding help that pops up on first time login does not
display how-to perform the steps. It is recommended is to use product
documentation for details.
GUI-2454
GUI-2040
GUI-2192
When size of Thunder configuration is large, configuration exchange
actions (e.g. config push/scan, config backup/restore) between
Harmony Controller and Thunder may fail.
GUI-3339
GUI-3344
Certain portions of Thunder configuration, especially shared objects
are not being deployed properly when pushed to Thunder from Harmony
Controller. Using ‘Device Utilities > Device CLI’ is recommended.
GUI-1748
GUI-2207
In some cases, to avoid disruption of environment or application traffic,
configuration push from Harmony Controller to Thunder may not succeed.
GUI-2630
A few system created Partitions may be visible to admins. These are for
internal use by Controller sub-system. Users are advised not to change
anything in those accounts.
HARMONY-18222
In case of assigning device license to VCS cluster, license is allocated only to
Master. License to blades is to be allocated manually.
CM-684
HARMONY-19113
Configuration management of Thunder VCS clusters from Controller
is not supported. Recommended is to convert VCS clusters to
multi-node HA clusters while registering with Controller. If these
devices are deregistered from Controller, recreation of VCS is
to be done manually.
HARMONY-17101
A Thunder VCS cluster deployed in different network from Controller
(behind firewall), cannot be registered using Tunnel feature. Traffic
from Controller to Thunder management port should be allowed in
firewall for it to work.

names. While upgrading from HC-4.2.1-Px, these names may change to the
new default values.

request rate, detailed service status etc., may be displayed incorrectly.
Please consider upgrading Thunder to ACOS 5.x.
HARMONY-19433
PDF reports display time as per time zone of Controller instance. This
may not match with the time shown in Harmony Portal because the portal
takes time zone of the client browser machine.
CM-680
GUI-1341
GUI-1342
When the configuration is being pushed from Controller which includes
password or similar fields, for Thunders these configuration changes
do not apply. Such changes are to be made directly in Thunder. After
that configuration can be scanned from Controller for synchronization.
CM-622
When more than one administrator changes configuration of applications
deployed on same Thunder partition via Harmony Portal, final configuration
may result in inconsistent state. As of now, it is advised that changes on
one partition should be done only from one place.
CM-667
When the Thunder configuration has a shared object, configuration push
from Controller fails. For making either the reference to shared object
is to be removed or changes are to be made directly in Thunder. Shared
object can be linked again after the configuration push. Or configuration
can be scanned from Controller for synchronization if changes are made
directly on Thunder.

selects ‘Convert’ option, scaleout functionality is disabled without
any warning.
HARMONY-20374
VCS cluster can only be registered to Harmony Controller if the IP
address on Thunder’s management interface is configured statically.
GUI-3659
While running a device CLI command from Harmony Portal, multiple
partitions of different devices can be selected to run command but
multiple partitions of same device cannot be selected. In case command
is to be run on multiple partitions of same device, command to change
partition is to be included in the snippet.
GUI-3548
HARMONY-20310
When VCS cluster is registered to Harmony Controller, Ethernet interface
information of the member devices is not available.
HARMONY-20502

not survive if the Controller or its configuration microservice restarts.
