Hello, after a induced failure of a whole site for testing reaction and restart, what would be sequence of actions to do from a physical point of view and from a gui point of view after powering on the hw components? In webadmin portal I see these 3 messages in host view events after SAN and then host and engine restart Detected new Host XXX. Host state was set to Up. Host XXX cannot access one of the Storage Domains attached to the Data Center Default. Setting Host state to Non-Operational. Failed to connect Host XXX to Storage Pool Default hosts and engine are fedora 18 with 3.2.2-1.1.fc18 and there are 6 fibrechannel storage domains, all down and in Unknown crossdatacenter status. one of them is flagged as "(master)"... I'm going to eventually send full logs, but I would like to ask if it is possible to send clearer messages inside the gui, for example what are the SDs that the host cannot access in case there are many of them. What does "Storage Pool Default" mean? The term "Default" is because my DC (and my cluster) are named "Default"? What exactly does it mean "Storage Pool"? The Master Data Domain or the combination of the defined storage domains? btw: In storage view I see: Failed to Reconstruct Master Domain for Data Center Default Thanks in advance Gianluca
