About 15% of my blades wont kickstart. I checked to see, and they all seem to be 100% compatible.

I currently do not own/direct access the kickstart server, I will build one later.

Is it possible they fat fingered the MAC address of the problem blades when they put them into the PXE server? As I can build them from a locally mounted virtual CD, but cannot build from PXE

At first I was getting a grub error. When I installed a baseline CentOS
locally, and then pxe booted for the build. I got a cannot find C0T0 which indicates it cannot find the first drive
(kickstart uses sda1), yet I look in the drac and I can see C0T0 drive as well as C0t1 drive (this is a raid 1 virtual drive no mirror)

So here is my big question: can I put my primary drive in slot sda2
on the blade… then DD the drive from the working blade, change the MAC
address in the network interface, change the hostname/IP address in
/etc/sysconfig/network and /etc/sysconfig/network-scripts/eth0 to build the drives?

What are the risks? what are the gotcha’s? what problems will I have DD
ing a drive that is currently the boot drive?

Any suggestions are welcome
