Page 128 highlights

vSphere Installation and Setup 5 Copy the ESXi installation script to the USB flash drive. cp ks.cfg /usbdisk 6 Unmount the USB flash drive. The USB flash drive contains the installation or upgrade script for ESXi. What to do next When you boot the ESXi installer, point to the location of the USB flash drive for the installation or upgrade script. See "Enter Boot Options to Start an Installation or Upgrade Script," on page 142 and "About PXE Configuration Files," on page 132. Create an Installer ISO Image with a Custom Installation or Upgrade Script You can customize the standard ESXi installer ISO image with your own installation or upgrade script. This enables you to perform a scripted, unattended installation or upgrade when you boot the resulting installer ISO image. See also "About Installation and Upgrade Scripts," on page 144 and "About the boot.cfg File," on page 154. Prerequisites n Linux machine. n The ESXi ISO image VMware-VMvisor-Installer-5.x.x-XXXXXX.x86_64.iso,where 5.x.x is the version of ESXi you are installing, and XXXXXX is the build number of the installer ISO image. n Your custom installation or upgrade script, the ks_cust.cfg kickstart file. Procedure 1 Download the ESXi ISO image from the VMware Web site. 2 Mount the ISO image into a folder: mount -o loop VMware-VMvisor-Installer-5.x.x-XXXXXX.x86_64.iso /esxi_cdrom_mount XXXXXX is the ESXi build number for the version that you are installing or upgrading to. 3 Copy the contents of cdrom to another folder: cp -r /esxi_cdrom_mount /esxi_cdrom 4 Copy the kickstart file to /esxi_cdrom cp ks_cust.cfg /esxi_cdrom 5 (Optional) Modify the boot.cfg file to specify the location of the installation or upgrade script using the kernelopt option. This step makes the installation or upgrade completely automatic, without the need to specify the kickstart file during the installation or upgrade. 6 Recreate the ISO image: mkisofs -relaxed-filenames -J -R -o custom_esxi.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /esxi_cdrom The ISO image now includes your custom installation or upgrade script. What to do next Install ESXi from the ISO image. 128 VMware, Inc.

Copy the ESXi installation script to the USB flash drive.
cp ks.cfg /usbdisk
6
Unmount the USB flash drive.
The USB flash drive contains the installation or upgrade script for ESXi.
What to do next
When you boot the ESXi installer, point to the location of the USB flash drive for the installation or upgrade
script. See
“Enter Boot Options to Start an Installation or Upgrade Script,”
on page 142 and
“About PXE
Configuration Files,”
on page 132.
Create an Installer ISO Image with a Custom Installation or Upgrade Script
You can customize the standard ESXi installer ISO image with your own installation or upgrade script. This
enables you to perform a scripted, unattended installation or upgrade when you boot the resulting installer
ISO image.
See also
“About Installation and Upgrade Scripts,”
on page 144 and
“About the boot.cfg File,”
on page 154.
Prerequisites
n
Linux machine.
n
The ESXi ISO image
VMware-VMvisor-Installer-
5.x.x
-
XXXXXX
.x86_64.iso
,where
5.x.x
is the version of
ESXi you are installing, and
XXXXXX
is the build number of the installer ISO image.
n
Your custom installation or upgrade script, the
ks_cust.cfg
kickstart file.
Procedure
1
Download the ESXi ISO image from the VMware Web site.
2
Mount the ISO image into a folder:
mount -o loop VMware-VMvisor-Installer-5.x.x-XXXXXX.x86_64.iso /esxi_cdrom_mount
XXXXXX
is the ESXi build number for the version that you are installing or upgrading to.
3
Copy the contents of
cdrom
to another folder:
cp -r /esxi_cdrom_mount /esxi_cdrom
4
Copy the kickstart file to
/esxi_cdrom
cp ks_cust.cfg /esxi_cdrom
5
(Optional) Modify the
boot.cfg
file to specify the location of the installation or upgrade script using the
kernelopt
option.
This step makes the installation or upgrade completely automatic, without the need to specify the
kickstart file during the installation or upgrade.
6
Recreate the ISO image:
mkisofs -relaxed-filenames -J -R -o custom_esxi.iso -b isolinux.bin -c boot.cat -no-emul-boot
-boot-load-size 4 -boot-info-table /esxi_cdrom
The ISO image now includes your custom installation or upgrade script.
What to do next
Install ESXi from the ISO image.
