  • After rebooting the host after the upgrade, the host still becomes unresponsive at initialization

Resolution

VMware ESXi includes a full range of host power management capabilities in the software. These can save power when an ESXi host is not fully utilized. You should configure your BIOS settings to allow ESXi the most flexibility in using the power management features offered by your hardware and then make your power management choices within ESXi.

To resolve this issue, set the power management of the host in the BIOS to OS control mode or an equivalent.

To manage the power operations for you server, contact your hardware vendor or check the server documentation.

For more information, see the Host Power Management in VMware vSphere 5 technical white paper.
