First Boot Overview
When a host that has not yet been provisioned with vSphere Auto Deploy boots (first boot), the host
interacts with several vSphere Auto Deploy components.
1 When the administrator turns on a host, the host starts a PXE boot sequence.
The DHCP Server assigns an IP address to the host and instructs the host to contact the TFTP
server.
2 The host contacts the TFTP server and downloads the iPXE file (executable boot loader) and an
iPXE configuration file.
3 iPXE starts executing.
The configuration file instructs the host to make a HTTP boot request to the vSphere Auto Deploy
server. The HTTP request includes hardware and network information.
4 In response, the vSphere Auto Deploy server performs these tasks:
a Queries the rules engine for information about the host.
b Streams the components specified in the image profile, the optional host profile, and optional
vCenter Server location information.
5 The host boots using the image profile.
If the vSphere Auto Deploy server provided a host profile, the host profile is applied to the host.
6 vSphere Auto Deploy adds the host to thevCenter Server system that vSphere Auto Deploy is
registered with.
a If a rule specifies a target folder or cluster on the vCenter Server system, the host is placed in that
folder or cluster. The target folder must be under a data center.
b If no rule exists that specifies a vCenter Server inventory location, vSphere Auto Deploy adds the
host to the first datacenter displayed in the vSphere Web Client UI.
7 (Optional) If the host profile requires the user to specify certain information, such as a static IP
address, the host is placed in maintenance mode when the host is added to the vCenter Server
system.
You must reapply the host profile and update the host customization to have the host exit
maintenance mode. When you update the host customization, answer any questions when prompted.
8 If the host is part of a DRS cluster, virtual machines from other hosts might be migrated to the host
after the host has successfully been added to the vCenter Server system.
