Changes in Behavior

 

The following changes in behavior are introduced with NorthStar Controller Release 6.0.0.

  • In northstar.cfg, the default value for the pcs_ecmp_tree_calculation parameter has been changed to False. Prior to this release, the default was set to True. For SR networks, users should set this parameter to True in order to enable ECMP tree calculation. To do so, use a text editor to modify the parameter in /opt/northstar/data/northstar.cfg:

    Then restart the PCS process:

  • Starting with Release 6.0.0, netflowd-related configuration in northstar.cfg is centralized on the application servers, and is no longer supported in northstar.cfg on analytics servers. There are two exceptions: “netflow_collector_address” and “netflow_port”. You must make any other netflowd-related changes to northstar.cfg on the application servers for them to take effect.

  • As of Release 6.0.0, NorthStar no longer supports CentOS and RHEL 6.x. Please upgrade your operating system to CentOS or RHEL 7.6 or 7.7. We are providing a procedure for changing your NorthStar application servers, analytics servers, and collectors from CentOS 6.x to CentOS 7.7 in such a way that your clusters and data remain intact. See Guidance for Migrating to CentOS 7 for NorthStar 6.0.0.

  • Due to the addition of the cMGD service in NorthStar 6.0.0, you must set a cMGD-root password. For a fresh install, you are prompted for this password. For an upgrade, you need to set the password and then restart the config:cmgd and config:cmgd-rest processes. See Guidance for Migrating to CentOS 7 for NorthStar 6.0.0.

  • As of Release 6.0.0, when you request a NorthStar license and enter the MAC address as 00:00:00:00:00:00, the license is no longer locked to a particular node. This allows operation of NorthStar, independent of a particular hardware. The same license can be used to run NorthStar on different servers.

  • As of Release 6.0.0, NorthStar no longer supports VMDK deployment.

  • If you are upgrading to NorthStar 6.0.0 from a NorthStar release earlier than 4.3 and you are not using analytics, you can upgrade using the procedure described in Installing the NorthStar Controller in the NorthStar Controller Getting Started Guide.

    If you are using NorthStar analytics, you must manually upgrade to NorthStar 6.0 using the procedure described in Upgrading from Pre-4.3 NorthStar with Analytics in the NorthStar Controller Getting Started Guide.

  • NorthStar Controller is Federal Information Processing Standard (FIPS) compliant. This only affects, and is a benefit to, customers with FIPS enabled on their Linux servers.
