Utilities Used By lininst

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.

The following are the variables used in grub and grub2:

•DT_OS_DISK — Sets the disk to deploy the Red Hat Enterprise Linux Server operating system.

•DT_OS_SRC — Sets the location from where to copy the kernel image and initial ramdisk files.

External Dependencies Of lininst.sh

The DT_PLATFORM variable is set during deployment by tkenvset.sh using platform discovery.

The lininst.sh script uses the unattended answer file with the grub utility and kernel image and initial ramdisk files to install the operating system files. For more information about preparing the unattended answer file, see Answer Files.

Answer Files (ks.cfg, ks-rhel5.cfg, ks-rhel6.cfg, and ks_rhel6_uefi.cfg)

Depending on the version of the Red Hat Enterprise Linux Server operating system, the ks.cfg, ks- rhel5.cfg, ks-rhel6.cfgor ks_rhel6_uefi.cfg (only in UEFI mode) files are the default names of the answer files to automate an unattended Red Hat Enterprise Linux Server installation. A sample copy of the ks.cfg/ks-rhel5.cfg/ks-rhel6.cfgfile is provided as part of the DTK download in the /opt/dell/toolkit/ template/configs directory. The ks.cfg/ks-rhel5.cfg/ks-rhel6.cfgfiles contain 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: The sample file provided to install Red Hat Enterprise Linux Server (version 5) in BIOS mode is named ks-rhel5.cfg. To use the sample ks-rhel5.cfgfile to install Red Hat Enterprise Linux Server (version 5) using lininst.sh, ensure that you rename the file to ks.cfg.

NOTE: The sample files provided to install Red Hat Enterprise Linux Server (version 6) are ks- rhel6.cfg (in BIOS mode), and ks_rhel6_uefi.cfg (in UEFI mode). To use the sample ks-rhel6.cfgfile to install Red Hat Enterprise Linux Server (version 6) using lininst.sh, ensure that you rename the file to ks.cfg. To use the sample ks_rhel6_uefi.cfg file to install Red Hat Enterprise Linux Server (version 6) using lininst.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.
