Disaster Recovery Installations and Upgrades
LogRhythm’s Disaster Recovery solutions are optimized to meet recovery objectives and minimize resource requirements. They provide an affordable option for enterprise business continuity planning while also providing continuous security monitoring. LogRhythm provides disaster recovery capabilities at each layer of the solution, including mirroring of the deployment configuration data, events and alarms to a secondary site. This allows for continued operation of LogRhythm’s Security Intelligence Platform if the primary site is disrupted. It also allows enterprises to adhere to disaster recovery policies to provide protection in case a primary site fails due to natural or man-made disasters.
Starting with LogRhythm 7.8, the High Availability (HA) and Disaster Recovery (DR) software was decoupled from the SIEM software. There will no longer be a new upgrade package provided for HA/DR with every SIEM release.

Bug # | Found in Version | Components | Release Notes |
---|---|---|---|
ENG-52241 | N/A | Disaster Recovery | Description: In Disaster Recovery Environments, LR SQL connections can timeout when using Windows Auth and Shared IP. Details: This issue is being caused by Windows Auth services attempting to perform Kerberos authentication with a connection string which does not have a valid SPN failing. On failover, the DR Failover IP is forcefully registered in Consul Keyspace. This is intentional and working as intended by Windows Auth. Workaround: Register SPN for the DR Failover IP in the active directory, or change the “EMDB Server” in Configuration Manager to a DNS name following any failover/back event. |
