Install Guide

NOTE: You can also download the latest drivers from the Dell Support website at support.dell.com.
4. Generate a system BIOS, BMC, RAID, and/or RAC/iDRAC conguration prole from the optimally congured source system.
Copy the generated conguration les to a read/write share onto the workstation or server.
NOTE: You can obtain the system BIOS, BMC, RAID, and/or RAC/iDRAC conguration les by booting from DTK
Linux ISO image and running the syscap.sh, raidcap.sh, and raccap.sh scripts.
5. Create an operating system answer le that contains unattended operating system software installation information.
6. Install an operating system on a Target Server.
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 _ue.cfg le 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 le 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_ue.cfg/ks_rhelx_ue.cfg (in UEFI mode) from /opt/dell/toolkit/template/
congs
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_ue.cfg to ks_ue.cfg.
13. Edit ks.cfg (in BIOS mode) or ks_rhelx_ue.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 le 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>.
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.
