Switch appliance roles

This procedure describes how to switch appliance roles, so that the primary appliance becomes the secondary, and the secondary appliance becomes primary. Perform this procedure as part of a manual failover process for DR clusters, in HA clusters as needed, if automatic failover is disabled.

Switching appliance roles may also be required as part of maintenance procedures. If you need to take the primary appliance offline, first perform a manual failover to the secondary appliance.

Do the following:

  1. Connect to the ASMS Administration Interface. For details, see Connect to and Utilize the Administration Interface.

    You can perform this procedure from either appliance, unless the primary appliance is already down.

  2. Enter 13. The console displays details about the cluster, including primary and secondary nodes and their statuses.

    For example:

    AlgoSec HA cluster status:
    1. Primary 10.10.0.101 - Up (this appliance)
    2. Secondary 10.10.0.102 - Up
    * VIP - 10.10.0.103
    10.10.0.101 -> 10.10.0.102 : Synced
    Please select an item or enter 'a' to abort:
    1. View cluster status details
    2. Remove HA configuration
    3. Switch roles
    4. View/Edit Cluster parameters
    5. Collect Logs

  3. Enter 3 to switch roles. The system prompts you to confirm.

  4. Enter y to confirm that you want to switch roles.

    The manual failover begins. Data from the primary appliance is synchronized to the secondary appliance, and the secondary appliance becomes active.

    When the process is complete, a success message appears, with the cluster status. An email notification is also sent to the Administrator user.

  5. Continue as instructed to do the following:

    1. Enter algosec_conf to return to the main menu.

    2. Enter 15 to run the Distributed Architecture configuration.

    3. Adjust your load units by doing the following:

      • Activate the DR load units
      • Disable / remove the primary load units
