Adding a second Manager device

Edit online

Before you begin

  • The existing Manager device must be associated with a management vault.
  • The existing Manager device must be "in sync" with its associated management vault.
  • In the Management Vault Options subsection of the Configure Management Vault page, System Configuration must be enabled.
  • Ensure that there is currently only one Manager device in the system. The system supports a maximum of two Manager devices.
  • The Manager device that you want to add to the system must be newly re-imaged with a software version that matches the version of the existing Manager device.

About this task

When a system employs multiple Manager devices, certain activities might be unavailable on one Manager device during normal operation. Activities such as upgrade, log collection, and email alert forwarding can only be performed by one Manager at a time. For example, at one point in time, email alerts might be sent by Manager A while at another point in time, email alerts are sent by Manager B.

In systems with multiple Manager devices, the associated management vault must be available in order to make configuration changes to the system. In the event of an outage affecting the management vault, the outage must be resolved before configuration changes can be made. If the outage cannot be resolved before configuration changes need to be made, then the Multiple Manager teardown procedure must be followed, which will return the system to single Manager device operation and allow configuration changes without management vault availability.

Procedure

  1. On the Settings tab, navigate to System > Multiple Manager.
  2. Select Enable multiple Managers within the system.
  3. Click Update. A Managers section displays.
  4. In the Manager URL or Hostname text box, enter the IP address or hostname of the Manager device you want to add to the system.
  5. Click Add.
  6. If the Manager device you are adding has different credentials than the defaults, a New Manager Credentials dialog box appears. Enter the username and password and click Save.

Results

Note: The SSL connection used to communicate with the new Manager device is allowed to proceed even for connections otherwise considered insecure. Use caution when entering the username and password of the new Manager device.

When the new Manager device is successfully added, a message displays: The new Manager device has been added successfully.

Note: In larger and/or older systems, this process can take a long time, and is proportional to the size of the Manager database.
