Diagnostics and recovery
Server diagnostics in DCImanager
Server diagnostics, along with automatic OS installation, is one of the main features of DCImanager. When a new server is added to the fleet, DCImanager will check the correctness of its operation and enter the configuration details into the database.
If a server has already been used before, the platform will analyze the status of installed components. If hard drives or other components were replaced during use, the information about the equipment will be updated automatically. Server health and performance are also checked. If a problem is detected, DCImanager will alert the administrator.
ISPsystem platform allows restoring the operability of virtual machines and physical servers if they do not start after reboot, or if remote connection is impossible. SystemRescueCD operating system is used for this purpose. This OS is intended for maintenance, diagnostics and debugging of the server.
To restore a physical server in DCImanager, the recovery template must first be installed on the server's location. It will then become available for use as an operating system and you can start the recovery procedure.
To restore the virtual machine in VMmanager, you will simply need to start the procedure in the server management menu. The diagnostics and recovery images are available out-of-the-box.
