Hi, dear!
Good day to you!
If you need to reinstall the IVS, you should make sure whether the data can be allowed to lose first.
And the following is the way to reinstall it.
Log in to the server through SSH.
Uninstall the software.
/home/ivstool/bin/Uninstall.sh all
Reinstall the IVS software again.
cd /share
./install.sh VCN_serve_IP VCN_server_gateway
Execute the above commands and reinstall the entire software successfully.
Best wishes!
