Hello everyone, and sorry for my poor english 
I've a big problem with a RAID 10 server where it is installed ESXi 4.0.0, which starts but fails to start VMs. I had shell access to the server and these are the relevant information related to the disks:
~ # fdisk -l

Maybe the problem is caused by the different contents of the disks. Using the vSphere Client, in fact, you can see the device but datasore is not detected.
Would you care to give me a hand to get out of this mess?
