At times, the partition HA cluster fails to start up correctly, leading to issues with database replicas and the secondary controller instance not reaching "standby". The "show system redundancy" command at the partition CLI can confirm this issue. Blades will be either "offline" or "failed", with a reason of "reconnecting" or "database disconnected" for an extended period (more than a few seconds).
Blades fail to initialize, causing tenants to not restart correctly.
Write transactions occurring during HA cluster formation can sometimes interfere with database initialization/replication, most often observed when multiple blades reboot together during a rolling upgrade.
Disable and re-enable the partition. If both partition controller instances are healthy (active/standby), use the "go-standby" command at the partition CLI.
The HA framework recognizes the database replication lockup and automatically resets the cluster.
