I am using VMware ESXi vSphere 5.0.0 and mounting a 6TB LUN from my Dell EqualLogic SAN. I am presenting the LUN using RDM (Raw Device Mappings) so as to be able to see all 6 TBs. So far, so good.
Then I use Gparted to create multiple partitions, several of which are over 2TBs in size. I used "gpt" to create the initial partition table. I am able to flag the /boot partition to be bootable. Again, so far, so good.
Next, I boot into CentOS 6.2 64-bit and label each partition as I defined it under the Gparted Live CD. No problem. I ran the install and everything installed just fine. Now... when I reboot, the VM under ESXi says no operating system found.
My question: how to make the bootable partitions discoverable and boot into my CentOS 6.2 install? I tried editing the firmware under ESXi to be EFI rather than BIOS, and then nothing worked.
