Disable or delete HA pools, force a failover, or update an HA pool for SolarWinds Platform products

This topic applies only to the following products:

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 SolarWinds Platform High Availability (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.

In the SolarWinds Platform Web Console, click Settings > My Deployment.
Select the pool you want to disable.
Toggle High Availability to Off.

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

Force a manual failover

When testing SolarWinds Platform 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 HA is enabled.
If the HA pool uses a virtual hostname, you may need to flush your browser's DNS cache by closing and reopening your browser.

In the SolarWinds Platform Web Console, click Settings > My Deployment.
Select the pool you want to failover manually.
Click Commands on the pool details section of the pool you want to failover.
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.

You can use Orion SDK to trigger HA failover without accessing the High Availability Deployment Summary page. See the support article on forcing HA failover without accessing the SolarWinds Platform Web Console.

Update your credentials, VIP address, virtual hostname, or active server

In the SolarWinds Platform Web Console, click Settings > My Deployment.
Select the pool to update.
Click Commands on the pool details section.
Click Edit Pool.
Update your credentials, (including TSIG certificates), VIP address, virtual hostname, or preferred active server.

The pool is saved with the changes you made.

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 SolarWinds Platform server, such as Additional or Main Polling Engine.
The HA Run Type indicates if the server is currently the active or standby server.

Remove HA pools

You may need to remove one or more HA pools to free an HA pool license or to change pool members.

When you remove a pool in a single subnet 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.

When you remove a pool in a multiple subnet pool, the DNS entry for the virtual host is still in your DNS server and associated with the server that is active when you remove the pool.

In the SolarWinds Platform Web Console, click Settings > My Deployment.
Select the pool you want to remove.
Click Commands on the Pool Details section.
Click Remove Pool.
