What I've found so far is.
1) Install windows directly to the micro server, it can see both the 3TB drives.
2) Install ESXi and follow the guide with a 120GB drive as RDM, everything is fine.
3) Install ESXi and follow the guide using the 3TB drives and everything seems fine in ESXi (The drives are correctly identified as 3TB) but when you come to add them in windows, it reads them as 512bytes.
Unless anyone else has managed to achieve this, I'm beginning to think it's just not possible, which is a shame as both the microserver BIOS and ESXi 5 both claim to support drives >2TB.
Firstly, try creating them with a specific controller. Like;
Code:
vmkfstools -a lsilogic -z /vmfs/devices/disks/[identifier] yourdisk.vmdk
It's worth naming the disk differently to before to create a new RDM.
Then, can you paste the result of both of the following commands
Code:
cat yourdisk.vmdk
ls -al
