TitleRU Manager Availability: Recovering from failover to normal mode 3
Question
The error message "RU Manager Availability: Recovering from failover to normal mode 3 " is seen on one system in an HA pair, nothing relating to the other system, and no fail over event takes place.
Environment
  • Availability 
  • Mobility
  • ExtremeWireless
  • Firmware 10.41.x
Answer
There are 2 messages relating to availability: 

(1) V2110 events: RU Manager Availability: Moving into failover mode 0 
(2) V2210 events: RU Manager Availability: Recovering from failover to normal mode 3 

1. This message is generated when ruMgr detects that link is down 
2. This message is generated when ruMgr re-establish the availability link. 

If you see (1) and (2) then there was actually a failover event. 

If you only see (2) then there may have been some packet loss and ruMgr have quickly re-established one side of the availability link.
