What to do next
On your iBFT adapter, reenable the option to boot to the iSCSI target, so the system will boot from the
LUN you installed ESXi on.
Installing or Upgrading Hosts by Using a Script
You can quickly deploy ESXi hosts by using scripted, unattended installations or upgrades. Scripted
installations or upgrades provide an efficient way to deploy multiple hosts.
The installation or upgrade script contains the installation settings for ESXi. You can apply the script to all
hosts that you want to have a similar configuration.
For a scripted installation or upgrade, you must use the supported commands to create a script. You can
edit the script to change settings that are unique for each host.
The installation or upgrade script can reside in one of the following locations:
n
FTP server
n
HTTP/HTTPS server
n
NFS server
n
USB flash drive
n
CD-ROM drive
Approaches for Scripted Installation
You can install ESXi on multiple machines using a single script for all of them or a separate script for each
machine.
For example, because disk names vary from machine to machine, one of the settings that you might want
to configure in a script is the selection for the disk to install ESXi on.
Table 211. Scripted Installation Choices
Option Action
Always install on the first disk on multiple machines. Create one script.
Install ESXi on a different disk for each machine. Create multiple scripts.
For information about the commands required to specify the disk to install on, see Installation and
Upgrade Script Commands.
Enter Boot Options to Start an Installation or Upgrade Script
You can start an installation or upgrade script by typing boot options at the ESXi installer boot command
line.
At boot time you might need to specify options to access the kickstart file. You can enter boot options by
pressing Shift+O in the boot loader. For a PXE boot installation, you can pass options through the
kernelopts line of the boot.cfg file. See About the boot.cfg File and PXE Booting the ESXi Installer.
