Scenario Conditions

Ruckus SmartZone 300 (SZ300) primary controller. 200 Ruckus R750 APs. Database corruption during operation. Controller web UI and API unresponsive. APs in standalone/last-known-good config. No secondary controller.

Injected Error Messages (3)

ruckus SmartZone 300 controller failure — SZ300 MariaDB database corrupted, ruckus controller web interface and northbound API returning errors, all 200 managed ruckus R750 APs lost LWAPP/SCG control channel, ruckus SmartZone cluster health: critical, controller unable to process AP join requests or push configuration changes
ruckus R750 AP operating in standalone mode — lost connection to SmartZone controller 45 minutes ago, ruckus AP serving cached WLAN configuration with last-known-good settings, new client authentication via WPA3-Enterprise failing (requires controller RADIUS proxy), ruckus AP unable to receive firmware updates or WLAN config changes, standalone mode limits: no load balancing, no band steering, no guest portal
wireless 802.1X authentication impaired after ruckus SmartZone failure — ruckus controller RADIUS proxy service offline, direct RADIUS auth path not configured on APs, WPA3-Enterprise clients failing authentication, WPA2-PSK SSIDs still functional, ruckus SmartZone handling RADIUS proxy for 200 APs now completely non-functional, only pre-authenticated clients maintaining sessions

Neural Engine Root Cause Analysis

The Ruckus SmartZone 300 controller is experiencing a critical MariaDB database corruption that has rendered the entire wireless infrastructure inoperable. This database corruption is preventing the controller from serving its web interface, northbound API, and most critically, managing the 200 Ruckus R750 access points that have lost their LWAPP/SCG control channels. The 12 correlated incidents within the same timeframe strongly suggest this is the primary failure point causing a cascading outage across the wireless network infrastructure.

Remediation Plan

1. Immediately assess controller hardware status and logs for signs of disk failure or memory issues. 2. Attempt MariaDB service restart and database integrity check using 'mysqlcheck --all-databases --check --auto-repair'. 3. If corruption persists, restore MariaDB from the most recent backup (typically located in /opt/ruckus/db_backup/). 4. If no backup available, perform database recovery using MariaDB recovery tools. 5. Restart SmartZone services in proper sequence: database first, then controller services. 6. Verify cluster health and AP reconnection status. 7. Test web interface and northbound API functionality. 8. Monitor AP join requests and configuration push capabilities.
