Deployment Guide

NOTE: The sample files provided to install CentOS Server (version 7.x) are ks-centos7.cfg (in BIOS mode), and
ks_centos7_uefi.cfg (in UEFI mode). To use the sample ks-centos7.cfg file to install CentOS Server (version 7.x)
using centinst7.sh, ensure that you rename the file to ks.cfg . To use the sample ks_centos7_uefi.cfg file to
install CentOS Server (version 7.x) using centinst7.sh, ensure that you rename the file to ks_uefi.cfg.
NOTE: See your operating system documentation for instructions on modifying the options in the kick start file to
customize the scripted installation of your operating system.
When you have completed all necessary modifications of the kick start file, save the completed file in the /opt/dell/toolkit/
systems/<target system> directory.
suseinst
The suseinst.sh sample script is used to perform an unattended installation of a supported SUSE Linux Enterprise Server operating
system. The variables and paths must be specified before the operating system can be installed.
CAUTION: It is recommended that you consult your SUSE Linux Enterprise Server operating system documentation and
unattended deployment documentation to develop a thorough understanding of the unattended installation process
before attempting to perform a full scripted deployment.
NOTE: While installing Linux, ensure that you install grub in the boot partition. Otherwise, you cannot boot to the
utility partition by pressing the <F10> key during reboot.
Utilities used by suseinst
grub — Used with the kernel image and initial ramdisk files, along with the unattended answer file to install the operating
system in BIOS mode.
grub2 — Used with the kernel image and initial ramdisk files, along with the unattended answer file to install the
operating system in UEFI mode.
Variables used
• DT_OS_DISK — Sets the disk on which to deploy the SUSE Linux Enterprise Server operating system.
• DT_OS_SRC — Sets the location from where to copy the kernel image and initial ramdisk files.
• DT_OS_PART — Sets the valid partition to install the grub files.
• DT_OS_IMG_PATH — Sets the network share where the operating system files are located.
• DT_SUSE_AUTOINST — Sets the network share from where the autoinst.xml file can be accessed.
External dependencies of suseinst.sh
The DT_PLATFORM variable is set during deployment by tkenvset.sh using platform discovery.
The suseinst.sh script uses the unattended answer file in conjunction with the grub utility and kernel image and initial
ramdisk files to install the operating system files.
autoinst.xml or autoinst_uefi.xml for SUSE Linux Enterprise server
The autoinst.xml and autoinst_uefi.xml file is the default name of the answer file that you use to automate an unattended SUSE Linux
Enterprise Server installation in BIOS and UEFI modes respectively. A sample copy of the autoinst.xml/autoinst_uefi.xml file is
provided as part of DTK download in the /opt/dell/toolkit/template/configs directory. The autoinst.xml/
autoinst_uefi.xml file contains the headings and parameters that instruct the installation utility to perform various configuration tasks.
Before a full deployment can be run, edit all appropriate headings and parameters, as necessary.
NOTE:
After installing SUSE Linux Enterprise, change the login password by editing the user node of the root user in
autoinst.xml/autoinst_uefi.xml. You can also encrypt the password file by changing false to true in <encrypted
config:type="boolean">false</encrypted>.
NOTE: See your operating system documentation for instructions on modifying the options in the autoinst.xml/
autoinst_uefi.xml file to customize the scripted installation of your operating system.
