We are currently trialing the StarWind product in our lab environment. We have it running in standalone mode on two Dell servers. Just last week one of the datastores went offline and now we are unable to remount it. ESXi discovers it but when trying to mount it only offers the option to format it.
VMware had a look at the issue and have said it is because the underlying LUN has changed. They also confirmed only one specific version of the StarWind software is supported and only on ESX4 classic (not i).
Unfortuantly we had a number of VM's running on this storage which are now lost unless anyone has any ideas on how to repair this?
Here is the VMware analysis
As per our conversation, the partition table is set up correctly on the affected LUN, however, the change in size of the LUN, prevented us from remouting the datastore.
I could see a new signature in the hexdump output, however, even after creating new partition we were unable to mount the volume.
It also appears that this type of storage was not certified or tested with ESXi 5, as per VMware HCL

In order to recover the data, please contact your storage vendor to check whether he will be able to recover the data.
You can also contact 3rd party recovery company to assist you with the data recovery

I can confirm no engineers made any changes to the storage.
