Install Guide

Installing Red Hat Enterprise Linux Server Operating System using DTK
CAUTION: Do not change the bootmode before executing installation scripts using syscfg. If you do, reboot the system
and start executing installation scripts.
NOTE: See your operating system documentation for instructions on modifying the options in the ks.cfg/ks-rhel x .cfg/
ks_rhel
x _uefi.cfg file to customize the scripted installation of your operating system, where x indicates the version of
the operating system.
To install Red Hat Enterprise Linux using the lininst.sh/ lininst7.sh script:
1. On the source system, navigate to the location of the required Red Hat Enterprise Linux operating system image.
2. Create a NFS share using the following command: vi /etc/exports.
3. Share /home/rhelshare.
NOTE: If the folder you want to share is /home, then the /etc/exports file must contain the “/home *(rw)” line.
4. Restart the NFS service.
5. Copy the operating system image to the NFS share.
6. Copy initrd.img for Red Hat Enterprise Linux to NFS share.
7. Copy vmlinuz from Red Hat Enterprise Linux operating system image to NFS share.
8. Boot DTK on the target machine.
9. Create the virtual disk using the raidcfg command.
10. Create a directory under /tmp. For example, os_src.
11. Mount the NFS Share to /tmp/os_src.
12. Copy ks.cfg/ks-rhelx.cfg (in BIOS mode) or ks_uefi.cfg/ks_rhelx_uefi.cfg (in UEFI mode) from /opt/dell/toolkit/template/
configs to NFS share on the source machine.
Here, x indicates the version of the operating system. In BIOS mode, rename the ks_rhelx.cfg to ks.cfg. In UEFI mode, rename
the ks_rhelx_uefi.cfg to ks.cfg.
13. Edit ks.cfg (in BIOS mode) or ks_rhelx_uefi.cfg (in UEFI mode) on the source system, where x indicates the version of the
operating system. Set the NFS IP address (where Red Hat Enterprise Linux images are available) and the NFS share path.
14. Export the environment variables as follows:
a. Run export DT_OS_DISK=/dev/sda on the disk device on which the Dell utility partition was created.
b. Run export DT_OS_SRC=/tmp/os_src where vmlinuz, initrd.img, and kickstart file are available.
c. Run export DT_HD=/dev/sda.
d. For Red Hat Enterprise Linux 7, run export DT_OS_NFS_LOC=<IP address of NFS>:/<path to os
source
>. Red Hat Enterprise Linux 7 deployment is supported only on Dell Precision R7910 and on Dell PowerEdge 13G
servers.
15. Run the partcfg.sh (at /opt/dell/toolkit/template/scripts/) script to create the Dell utility partition and OS partition in BIOS or
UEFI mode.
Ensure that the correct device is set to DT_HD and DT_OS_DISK..
16. From /opt/dell/toolkit/template/scripts, run /lininst.sh (for 6.x) or /lininst7.sh (for 7.x) script.
The server reboots to the grub prompt. The Red Hat Enterprise Linux operating system unattended installation is initiated.

Converting to RACADM and installing Red Hat Enterprise Linux Server Operating System
using RACADM scripts
CAUTION: Do not change the bootmode before running installation scripts using syscfg. If you do, reboot the system
and start running installation scripts.
NOTE: See your operating system documentation for instructions on modifying the options in the ks.cfg/ks-rhel x .cfg/
ks_rhelx_uefi.cfg file to customize the scripted installation of your operating system, where x indicates the version
of the operating system.
