4.6.7 Cluster Service
The Cluster service is a system component used to control activities on a single node. When one or
several device(s) are malfunction, it can switch to the slave device to replace the work accordingly.
There are two standards when the master device is malfunction: 1) Device is offline. 2) Device storage is
damaged.
Important
Please go to the WEB of the slave device to set the cluster setup of the master device and slave
device .
4.6.7.1 Cluster IP
About Cluster service: when master device is malfunction, the slave device can use the master device
configuration and virtual IP address to replace the work (monitor or record) accordingly. When you use
the virtual IP to access the device, he can still view the real-time video and there is no risk of record loss.
Once the master device becomes properly, the slave can still work until you use the WEB to fix manually.
During the whole process (the master device is working properly>master device is malfunction>master
device becomes work properly again), you can use this virtual IP to access the device all the time.
After you set the right cluster IP, you can use the cluster IP to login the device. See Figure 4-158.
