Will the hardware support Quick Boot after upgrading to vCenter 6.7 ?

Answer

Quick Boot is a vSphere feature that speeds up the upgrade process of an ESXi server. A regular reboot involves a full power cycle that requires firmware and device initialization. Quick Boot optimizes the reboot path to avoid this, saving considerable time from the upgrade process.

Not all servers or configurations support the Quick Boot feature. The Update Manager UI will present Quick Boot as an option for servers that support the feature, however for some servers this option will not be available and your host will perform regular reboot rather than a Quick Boot.

You may see this issue if:

• Host platform is not supported.
• Host is configured to use a TPM.
• passthru devices configured for VMs on your host.
• vmklinux drivers loaded on your host.
• Other non-certified drivers loaded on your host
• Quick Boot is disabled in the Update Manager UI.

To check if your system is compatible with Quick Boot, run this command on the ESXi host from the shell:

/usr/lib/vmware/loadesx/bin/loadESXCheckCompat.py

Note: This script will list all issues preventing Quick Boot from being available on the ESXi host
