Install Guide

2. Perform the steps 2 to 11 from the section Installing SUSE Linux server Operating System using DTK.
3. From /opt/dell/toolkit/converter, run the command python dtktoracadm.py or python dtktoracadm.py
linux_scripts.lst, where linux_scripts.lst is the input file which contains the list of script files to be converted to
equivalent RACADM scripts.
The RACADM converted scripts are available in /opt/dell/toolkit/converter/racscripts.
4.
From /opt/dell/toolkit/converter/racscripts/, run the partcfg.sh script to create the Dell utility partition and OS
partition in BIOS or UEFI mode.
NOTE: Ensure that the correct device is set to DT_HD, DT_OS_DISK, and DT_OS_PART.
5. Run /suseinst.sh script, from /opt/dell/toolkit/converter/racscripts.
The server reboots to the grub prompt. The SUSE Linux Enterprise Linux operating system unattended installation is initiated.
Installing CentOS Linux Server Operating System
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-
centos x .cfg/ks_centos x _uefi.cfg file to customize the scripted installation of your operating system, where x indicates
the version of the operating system.
To install CentOS Linux using the centinst6.sh/ centinst7.sh script:
1. On the source system, navigate to the location of the required CentOS Linux operating system image.
2. Create a NFS share using the following command: vi /etc/exports.
3. Share /home/centosshare.
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 CentOS Linux to NFS share.
7. Copy vmlinuz from CentOS 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-centosx.cfg (in BIOS mode) or ks_uefi.cfg/ks_centosx_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_centosx.cfg to ks.cfg. In UEFI mode, rename the
ks_centos
x_uefi.cfg to ks.cfg.
13. Edit ks.cfg (in BIOS mode) or ks_centosx_uefi.cfg (in UEFI mode) on the source system, where x indicates the version of the
operating system. Set the NFS IP address (where CentOS 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 CentOS 7.0 , 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 /centinst6.sh or /centinst7.sh.
The server reboots to the grub prompt. The CentOS Linux operating system unattended installation is initiated .
