Switching a Primary HA Host to Active

You can set the primary high-availability (HA) host to be the active system.

The primary HA host must be the standby system and the secondary HA host must be the active system.

If your primary host is recovered from a failure, it is automatically assigned as the standby system in your HA cluster. You must manually switch the primary HA host to be the active system and the secondary HA host to be the standby system.

  1. On the navigation menu, click Admin.
  2. On the navigation menu, click System Configuration.
  3. Click the System and License Management icon.
  4. In the System and License Management window, select the secondary HA host.
  5. From the toolbar, select High Availability >Set System Offline.

    Your primary HA host is automatically switched to be the Active HA host.

    Note:

    Your JSA user interface might be inaccessible during this time. To return the secondary HA host to standby and return the primary HA host to active run either of the following commands:

    • From the active host run:

      /opt/qradar/ha/bin/ha giveback

      The host that was active is now the standby host and the standby host is now the active host.

    • From the standby host run:

      /opt/qradar/ha/bin/ha takeover

      The host that was on standby is now the active host and the host that was the active host is now the standby host.

  6. In the System and License Management window, select the secondary HA host.
  7. From the toolbar, select High Availability >Set System Online.

    Your secondary HA host is now the standby system.

When you can access the System and License Management window, check the status column. Ensure that the primary HA host is the active system and the secondary HA host is the standby system.
