Alarm Information
Handling Process

• You must ensure the security of the video on the server and cannot perform invalid deletions on the database and camera. Otherwise, the video on the server may be damaged.
• The troubleshooting process in the case that the network is disconnected or a fault occurs on the server is as follows:
    1. Choose StartRun. Enter the cmd command to open the command line window.
    2. Enter a ping command in the following format:
    C:\Documents and Settings\Administrator>ping [IP address of the server]
    3. If the system displays time out, it indicates that the network is disconnected. Check the network, and then check whether the network cable is correctly connected.
• Check whether the server is forcibly powered off or restarted by others due to an exception. Make sure that the network connection is normal and the server runs normally. Then, start services as follows:
    1. Connect to the NVR server through the SSH client tool.
    2. Log in the server and enter the command cd /hinvs/scripts/ to access the /hinvs/scripts directory.
    3. Check whether service processes are started. Enter the following command:
    ./nvsctrl status
    Normally, the following service processes are displayed:
    Checking for service PNM ....
    root     15425     1  0 10:35 ?        00:00:00 PNM_SOAPSvr
    root     15438     1  0 10:35 ?        00:00:00 NVS_PNM
    Checking for service PSM ....
    root     15231     1  0 10:35 ?        00:00:00 NVS_ClientAppSvr

    root     15170     1  0 10:35 ?        00:00:00 NVS_SysAdminSvr
    root     15421     1  0 10:35 ?        00:00:00 APA_Server
    root     15381     1  1 10:35 pts/2    00:00:01 ./snmpapp
    root     15273     1  0 10:35 ?        00:00:00 PSM_SOAPSvr
    4. Start the services.
? If no service is started, enter the following command:
    ./nvsctrl start
? If a service is not started, enter the following command:
    ./nvsctrl restart
