In order to complete a (Software/Hardware) upgradation, we need to Power down or Reboot the ESX/ESXi host server. Before proceeding with the Shutdown/Reboot of the ESX/ESXi sever, we need to follow the shutdown procedure.
By following the technical procedure we can ensure the stability of the virtual machines hosted in the ESX/ESXi server.
Here is the list,
1. Logon to vSphere client.
2. Shutdown all the virtual machines (Operating system’s Graceful PowerDown is recommended). If the ESX/ESXi host server belongs to Cluster environment, we can migrate the virtual machines to another host. Before the Shutdown/Reboot change the ESX/ESXi server into maintenance mode.
In a cluster environment, if a host enters into maintenance mode all the hosted virtual machines will start migrating to another host within the Cluster environment. This function works with the help of VMware vMotion technology.
3. Select the ESX/ESXi host server for Shutdown/Reboot.
4. Right Click the host and click on the appropriate action (Shutdown or Reboot).
· Selecting Reboot will Shutdown and PowerOn the ESX/ESXi server.
· Selecting Shutdown will fully PowerDown the server and we need to manually Power the system back.
5. Provide a reason for the Shutdown/Reboot. The information is added to the log.
