To reconfigure the collector HA pair, complete the following:

  1. Log in to the collector CLI as admin.
  2. Run the reset tunclient command:

    col2 (primary)> reset tunclient

    Launching "show version" on "172.19.2.62"...

    Notice: This operation will clear all Tunnel client

    configuration and shut down the local Tunnel service.

    Continue? (y/n) [n]: y

    +++ Stopping OpenVPN Service ... OK

    +++ Configuring OpenVPN Service ... OK

    +++ Clearing Client Config ... OK

    +++ Adjusting ACLs ... OK

    Launching "failover tunclient reset" on "172.19.2.62"...

  3. Run the configure tunclient command and configure it with OC VIP address (Server Public Virtual Name or VIP address):

    col2(primary)> config tunclient

    NOTICE: The inactivity timeout is being disabled temporarily while this command is run.

    Launching "show version" on "172.19.2.62"...

    NOTICE: The time zone on this system is US/Pacific.

    This MUST match the Operation Center time zone for registration to be successful.

    If the time zones are not equal, you must first use "configure server" to set

    the collector time zone to match.

    PLEASE NOTE: Changing the time zone WILL REQUIRE A SYSTEM REBOOT.

    Do you want to continue registration? (y/n) [n]: y

    +++ Configuring Tunnel Registration Settings

    Registration Server/IP [e.g., example.com]: 172.19.2.66

    Registration protocol (http|https) [https]:

    Registration username: admin

    Registration password:

    Register this system? (y/n) [y]:y

    .......

    This is going to take a long time (really long, about 40 + minutes)

  4. Repeat the above steps for each collector.

The NetMRI system (OC and two collectors) is now migrated as a failover pair.

Note

If devices were discovered from both collectors, e.g. when a device has a few interfaces, these devices are displayed in grey without a sim link to the device viewer on the collector which did not discover first. After the system is migrated, the following issue is observed for one of the collectors (second): On the Network Explorer > Discovery page, the devices listed on the left from the initial collection and discovered by both collectors cannot be discovered or deleted using the Discover Now or Delete button. However, you can discover them from the  Settings icon > Discovery Settings > Seed Routers/CIDR.
