When we add ADC into ADM, the page of adding ADC to ADM may stuck at "Trying to connect XXX". If we open a new page to check ,we may notice that ADC is added to ADM , but the hostname is not displayed.
And we may found the mas_inventory process is not running as no output is displayed for the following command.
bash-3.2# ps aux | grep inventory
The issue can be solved after rebooting ADM
Inventory process was stopped , so the request to get hostname was not sent out by ADM to ADC.
In a normal environment, we will see "./mas_inventory CONTROL_IPC_SOCK=/tmp/mps/ipc_sockets/mps_control_sock" in the result of ps command, as below. If it is not listed , we will see this issue.
bash-3.2# ps aux | grep inventory
nobody 2855 0.0 0.8 452092 270400 - I 4Jan24 508:24.76 ./mas_inventory CONTROL_IPC_SOCK=/tmp/mps/ipc_sockets/mps_control_sock
