Lost datastore after converting RAID 1 array to RAID 5 on Dell PE...

I have a Dell PE R415 that I have upgraded to ESXi v6.0 allong with adding a third drive to an array, converting from a RAID 1 to RAID 5 to increase storage from 4TB to 8TB.  Upon reboot, I discovered my datastore was no longer mounted.  I have dug around and the other posts I have found don't match my situation.  When I list the contents of /dev/disks I see this:

[root@localhost:/dev/disks] ls -al

Not so long ago, I watched a vmware support tech fix this very problem on a paid deploy, but it went too fast for me to follow, but basically she recreated the link between the vmfs on the local Dell disk and a datastore. 

Can someone point me in the correct direction?

Any assistance much appreciated!

I want to ask a small question. You can't see the datastore right now, can you? Does it ask you to fortmatize the disk when you want to add it again?

Tayfun,

No, I cannot see the datastore from the vSphere Client.  And yes, it says it wants to format the disk and that all data will be lost when I try to add it.

Hi Clay

please read Create a VMFS-Header-dump using an ESXi-Host in production | VM-Sickbay

if you provide a dump like that I can tell you more about the state of your datastore
