servers for redundancy. If communication fails during background key server 
path testing, this RAS ticket will be generated. A separate RAS ticket will be 
created for each key server that fails.
Detection Scenarios Library detects that communication with a key server is not successful.
Root Causes • Primary/secondary key server is not connected properly.
• Primary/secondary key server is not configured properly.
• Library Ethernet settings are not configured properly.
