Hi.
Thanks for your suggestions. That didn't go well. What exactly I am trying is.
Pre condition.
1. System is installed with rhel version(No specific version).
Target.
1. Copy the RHEL customized ISO to the system disk and start the installation from that ISO when system boots p next time.
Procedure followed.
1. Copy the ISO to RHEL preinstalled system.
2. Modified the grub.conf with below lines so that I can boot the system to start the installation.
title RedHat Install
root (hd0,2)
kernel /boot/vmlinuz ro root=UUID=9684465d-8ded-43cc-8069-de5ff713dd40 ks=hd:sda2:/ks-sa.cfg repo=/mnt/isodir stage2=hd:sda2:/images/install.img
initrd /boot/initrd.img
3. created the tar out of cdrom contents and kept in / dir 3. Below are is the content of kickstart file to copy the repo to tmpfs created out of system RAM.
mount -t tmpfs -o size=1g tmpfs /mnt/isodir mkdir /mnt/isomount
mount /dev/sda2 /mnt/isomount
cd /mnt/isodir
tar -xzvf /mnt/isomount/repo.tgz
umount /dev/sda2
This is somehow not picking up the ISO since anaconda look for ISO and stage 2 in sda2. Is there any way I can do the installation from tmpfs ?
Thanks
Ganesh

Howdy, you might need to clear the disk before you configure it.
Try adding this line:
clearpart --initlabel --all --drives=sda

Subject: Install RHEL6 from tmpfs
Hi
I have a situation where I can access the system remotely from BMC and access the console and need to do the automated kickstart installation. Presently system is installed with RHEL6 and followed the below step for hard disk based installation.
1. Copied automated ks.cfg to vmlinuz, initrd.img and images dir to / folder from ISO.
Modified the grub.conf with below lines.
title RedHat Install
root (hd0,2)
kernel /boot/vmlinuz ro root=UUID=9684465d-8ded-43cc-8069-de5ff713dd40 ks=hd:sda2:/ks-sa.cfg repo=/mnt/isodir stage2=hd:sda2:/images/install.img
initrd /boot/initrd.img
2. created the tar out of cdrom contents and kept in / dir 3. Below are is the content of kickstart file to copy the repo to tmpfs created out of system RAM.
harddrive --partition=tmpfs --dir=/mnt/isodir
Preinstall section code to create the install repository
mount -t tmpfs -o size=1g tmpfs /mnt/isodir mkdir /mnt/isomount mount /dev/sda2 /mnt/isomount cd /mnt/isodir tar -xzvf /mnt/isomount/repo.tgz umount /dev/sda2
reboot the system and boot from "Redhat Install" and this triggers the installation. Presently I got struck in partitioning the sda. Any one tried this before? Is there any suggestions or good pointers?
Thanks
Ganesh
