Manage HA pools

Updated: 12-1-2016

Use the High Availability Deployment Summary page to view and manage your pools and to view the pool member type.

Disable HA pools

During an upgrade or maintenance procedures on your HA pool members, you must disable your pool. HA pools can also be disabled when you no longer have sufficient HA pool licenses for the number of enabled pools.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to disable.
  3. Toggle High Availability to Off.

You can also disable the entire feature on the High Availability Settings page.

Remove HA pools

You may need to delete an HA pool to free an HA pool license or to change pool members.

When you remove a pool, the VIP is still reserved in the database and is not recycled so you can re-establish the pool without modifying your network or device settings.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Select the pool you want to delete.
  3. Click Commands on the Pool Details section.
  4. Click Remove Pool.

A failover audit event is logged when you remove a pool.

Force a manual failover

When testing SolarWinds High Availability and network configuration changes or when upgrading, you can failover to the standby pool member manually.

Failover can only occur when both pool members are up, the pool is enabled, and High Availability is enabled.

  1. In the Orion Web Console, click Settings > All Settings > High Availability Deployment Summary.
  2. Click Commands on the pool details section of the pool you want to failover.
  3. Click Force Failover.

The pool fails over to the secondary server and a failover audit event is logged that records who forced the failover and when it occurred.

View the pool member type

In addition to polling metrics, individual pool members list a Server Type and an HA Run Type. Select a pool member to view the pool member type and other polling information.

  • The Server Type displays the type of Orion server, such as Additional or Main Polling Engine.
  • The HA Run Type indicates if the server is currently the active or standby server.
