Some media server has been "offline" with not reachable by master (6)
We have a small NBU 8.2 domain environment with one master, four media servers and also share one TL with 2 SSO TDs. All of them work fine except for one media server is offline with not reachable by master (6) via nbemmcmd listhosts. This problematic media server can be activated/online only for nearly 5 minutes every time, then it would be offline again. Notes: there is almost no any more errors/warnings in all the relevant logfiles including VxUL logs. # # # nbemmcmd -listhosts -display_server -machinename erp-fzyf -machinetype media -verbose|grep State MachineState = not reachable by master (6) # # # nbemmcmd -updatehost -machinename erp-fzyf -machinetype media -machinestateop set_master_server_connectivity -masterserver erpbak NBEMMCMD, Version: 8.2 Command completed successfully. # # # nbemmcmd -listhosts -display_server -machinename erp-fzyf -machinetype media -verbose|grep State MachineState = active for tape and disk jobs (14) # # # nbemmcmd -listhosts -display_server -machinename erp-fzyf -machinetype media -verbose|grep State MachineState = active for tape and disk jobs (14) # # # nbemmcmd -listhosts -display_server -machinename erp-fzyf -machinetype media -verbose|grep State MachineState = not reachable by master (6) # # This problematic media server appears with the machinestateopcode = <9> every 10 minutes.
