vSphere Installation and Setup 5 In the host BIOS settings, enter the iBFT adapter BIOS configuration, and change the adapter parameter to boot from the iSCSI target. See the vendor documentation for your system. 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 installled ESXi on. Installing, Upgrading, or Migrating Hosts Using a Script You can quickly deploy ESXi hosts using scripted, unattended installations or upgrades. Scripted installations, upgrades, or migrations 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, upgrade, or migration, you must use the supported commands to create a script. and 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 n HTTP/HTTPS n NFS n USB flash drive n CDROM 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 7‑1. Scripted Installation Choices Option Action Always install on the first disk on multiple machines. Install ESXi on a different disk for each machine. Create one script. Create multiple scripts. For information about the commands required to specify the disk to install on, see "Installation and Upgrade Script Commands," on page 145. Enter Boot Options to Start an Installation or Upgrade Script You can start an installation or upgrade script by typing boot command-line 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," on page 154 and "PXE Booting the ESXi Installer," on page 129. A ks=... option must be given, to specify the location of the installation script. Otherwise, a scripted installation or upgrade will not start. If ks=... is omitted, the text installer will proceed. 142 VMware, Inc.
