There is a need to change ESXi root password to the latest one. This ESXi server is manged by vCenter.
I am using the following method to change the password by entering the old password.
Take Remote Board ==> VMware ESXi(DCUI) ==> System Customization ==> Configure Password
Once the password is changed on ESXi server, is it necessary to make any password changes on vCenter to reflect the new password?
When a Host joins a vCenter than a "vpxa" user is created and this is what vCenter or better the vpxd is used for managing a Host.
So changing the root pw does not effecting vCenter.
