Lock down Mode:
In lockdown mode, all operations must be
performed through vCenter Server.
With
vSphere 6 we are introducing a couple of new concepts
- Normal Lockdown Mode
- Strict Lockdown Mode
- Exception Users
Normal
Lockdown :
If the connection to
the vCenter Server system is lost and access through the vSphere Web Client is
no longer available, privileged accounts can log in to the ESXi host’s Direct
Console Interface and exit lockdown mode
Strict Lockdown Mode :
If the
connection to vCenter Server is lost and the vSphere Web Client is no longer
available, the ESXi host becomes unavailable unless the ESXi Shell and SSH
services are enabled and Exception Users are defined. If you cannot restore the
connection to the vCenter Server system, you have to reinstall the host.
