Netiq Advanced Authentication Global Master Down


Hi All 

I Have question regarding NetIQ Advanced authentication clustering 

We have two node AA cluster, one for Global Master (Node1) and one for DB Server (Node2)

currently our Global master the detected in the information cluster is down, and all the authentication currently goes to node2 
in cluster log it show an information like : 

xxxx-xx-xx:xx:xxx ERROR ForkPoolWorker-7892 [aucore.scripts.celery_tasks.monitor_db] Failed to connect

psycopg2.OperationalError: connection to server at "node1" (, port 5432 failed: timeout expired

My question is how to start Global master again? 

PS: I already stop and start the AAUTH and RISK Service but can't solve this problem 

Thanks for any advice or input
