The eSpace IVS C/S client is disconnected from the server and cannot be logged in to by any user.

Steps:

1. Check whether the network between the PC client and the server is properly connected.

1. Log in to the PC client and the server and run the ping command to check the network between the PC client and the server.
   • If the PC client and the server can be pinged, go to 2.
   • If the PC client and the server cannot be pinged, go to the next step.
2. On the PC client and the server, run the ping command to ping the gateway to which the PC client or the server belongs.
   • If both gateways can be pinged, the network between the PC client and the server is incorrectly configured. Locate and rectify the network fault, and check whether the fault is rectified.

     If the fault is rectified, no further action is required. If the fault persists, go to step2.

   • If either gateway cannot be pinged, the network on that side is abnormal. Locate and rectify the network fault and check whether the fault is rectified.

     If the fault is rectified, no further action is required. If the fault persists, go to the next step.

     NOTE:

     Log in to the server using an SSH tool or the management port and restart the server. If you fail to log in to the server in neither mode, restart the server in the equipment room.

     After the server is restarted, recheck the network between the PC client and the server.

1. Log in to the server as the root user.
2. Run the df -h command to check the disk space usage.
   • If the usage of each disk partition is within 100%, go to 3.
   • If the usage of any disk partition reaches 100%, go to the next step.
3. Go to the disk partition whose usage reaches 100% and run the du -h --max-depth=1 command to check for large files and folders.
4. Repeat 3 to find out all large files and folders in the disk partition.
   • If the large files are not log files, contact Huawei technical support engineers.
   • If the large files are log files, run the rm log file name to delete them, and check whether the fault is rectified.

     If the fault is rectified, no further action is required. If the fault persists, go to the next step.

5. Restart the database.
   1. Log in to the server as the root user.
   2. Run the cd /home/ivstool/bin command.
   3. Run the ./service.sh restart pgdb command to restart the database.
   4. Run the ps -ef|grep postgres command to check whether the database is successfully restarted.

      If the following information is displayed, the database is successfully restarted:

      postgres  10167      1  0 Mar06 ?        00:01:06 /bin/bash - /home/postgres/bin/ivsdb_monitor.sh start
      postgres  10208  10167  0 Mar06 ?        00:00:04 /home/postgres/bin/postmaster -D /DB_DATA/data
      postgres  10210  10208  0 Mar06 ?        00:00:00 postgres: logger process
      postgres  10212  10208  0 Mar06 ?        00:00:01 postgres: checkpointer process
      postgres  10213  10208  0 Mar06 ?        00:00:00 postgres: writer process
      postgres  10214  10208  0 Mar06 ?        00:00:00 postgres: wal writer process
      postgres  10215  10208  0 Mar06 ?        00:00:10 postgres: autovacuum launcher process
      postgres  10216  10208  0 Mar06 ?        00:00:23 postgres: stats collector process

   5. After the database is restarted, run the reboot command to restart the server. Ensure that all services can properly connect to the database.
   6. Check whether the fault is rectified.

      If the fault is rectified, no further action is required. If the fault persists, go to step4.

3. Restart the SMU.

4. collect the logs and contact Huawei support.
