vSphere Installation and Setup %firstboot %packages --level option not supported in ESXi 5.x. Not supported in ESXi 5.x. Disk Device Names The install, upgrade, and installorupgrade installation script commands require the use of disk device names. Table 7‑3. Disk Device Names Format Examples Description VML vml.00025261 The device name as reported by the vmkernel MPX mpx.vmhba0:C0:T0:L0 The device name NOTE When you perform a scripted upgrade from ESX 4.x to ESXi 5.x, the MPX and VML disk names change, which might cause the upgrade to fail. To avoid this problem, use Network Address Authority Identifiers (NAA IDs) for the disk device instead of MPX and VML disk names. After you obtain the NAA ID or VML number, typically from the BIOS of the storage adapter, you can modify the kickstart file (ks.cfg) for each host to identify the disk device by the NAA ID or VML number. Some devices do not provide an NAA ID. In these circumstances, an MPX Identifier is generated by ESXi to represent the LUN or disk. The identifier takes a form similar to the canonical name of previous versions of ESXi with the mpx. prefix. This identifier can be used exactly as the NAA ID. See Knowledge Base article 1014953. About the boot.cfg File The boot loader configuration file boot.cfg specifies the kernel, the kernel options, and the boot modules that the mboot.c32 boot loader uses in an ESXi installation. The boot.cfg file is provided in the ESXi installer. You can modify the kernelopt line of the boot.cfg file to specify the location of an installation script or to pass other boot options. The boot.cfg file has the following syntax: # boot.cfg -- mboot configuration file # # Any line preceded with '#' is a comment. title=STRING kernel=FILEPATH kernelopt=STRING modules=FILEPATH1 --- FILEPATH2... --- FILEPATHn # Any other line must remain unchanged. The commands in boot.cfg configure the boot loader. Table 7‑4. Commands in boot.cfg . Command Description title=STRING kernel=FILEPATH Sets the boot loader title to STRING. Sets the kernel path to FILEPATH. 154 VMware, Inc.

When you perform a scripted upgrade from ESX 4.x to ESXi 5.x, the MPX and VML disk names
change, which might cause the upgrade to fail. To avoid this problem, use Network Address Authority
Identifiers (NAA IDs) for the disk device instead of MPX and VML disk names.
After you obtain the NAA ID or VML number, typically from the BIOS of the storage adapter, you can
modify the kickstart file (ks.cfg) for each host to identify the disk device by the NAA ID or VML number.
Some devices do not provide an NAA ID. In these circumstances, an MPX Identifier is generated by ESXi to
represent the LUN or disk. The identifier takes a form similar to the canonical name of previous versions of
ESXi with the
mpx.
prefix. This identifier can be used exactly as the NAA ID. See Knowledge Base article

About the boot.cfg File
The boot loader configuration file
boot.cfg
specifies the kernel, the kernel options, and the boot modules
that the
mboot.c32
boot loader uses in an ESXi installation.
The
boot.cfg
file is provided in the ESXi installer. You can modify the
kernelopt
line of the
boot.cfg
file to
specify the location of an installation script or to pass other boot options.
The
boot.cfg
file has the following syntax:
# boot.cfg -- mboot configuration file
#
# Any line preceded with '#' is a comment.
title=
STRING
kernel=
FILEPATH
kernelopt=
STRING
modules=
FILEPATH1
---
FILEPATH2
... ---
FILEPATHn
# Any other line must remain unchanged.
The commands in
boot.cfg
configure the boot loader.
