Cannot Kickstart CentOS 6 On Dell Blade Error Cannot Find C0t0

I have an intermittent problem with my Dell blades, out of 80 blades 69
of them kickstarted CentOS 6 fine using PXE
The other 11, I get a c0t0 not found error (indicating it is not finding the local disk on the blade).

I can remote mount the iso image and do a basic install of CentOS on these blades, but when I go to do a pxe boot it gives me that error again.

I have googled the issue and come up empty handed. Dell told us to install CentOS 6 minimal ISO then pxe install the server. This has been unsuccessful. I get the local ISO to install but the pxe fails again.

Since the kickstart file defines the disk as sda1 I am supposing that it is really a hardware problem. But I am told by coworkers who handed it off to me that it is a known issue with CentOS and Dell blades.

These are two internal disks on the blade.

Any suggestions?

    Nahhh… First, I suspect that those 11 blades are a slightly different model – newer, or whatever. When we first got some Dell R720s was when we ran into CentOS calling the NIC em1 instead of eth0, while *other*
    R-series servers we got the same time were still eth0.

    I’m afraid you’re going to have to put conditionals into the ks, or maybe, the way we do, write a CGI that creates one on the fly, to tell it to look for those drives under those names. *shrug* We did just that in our CGI, and chose CentOS 6, 64 bit, R720 for them.
