Details: Both active server My_Active_Hostname and passive server My_Passive_Hostname cannot detect the quorum server. Suggestion: Please make sure the quorum server is running. Check to make sure that the active server My_Active_Hostname, passive server My_Passive_Hostname, and the quorum server are all connected properly. Description The active server and the passive server cannot detect the quorum server via PING. Cause The connection between the active/passive servers and the quorum server is abnormal. Resolution 1. Do the following to make sure the quorum server can accept and respond to PING messages from the active and passive servers: • Make sure that there are no hardware issues, such as loose cables, broken cables, or switch malfunctions. • Make sure that the connections between the hosts (active and passive servers) and the quorum server are not blocked by any network rules. • Make sure that the routing rules on all hosts, switches, and routers are configured correctly. 2.
