Just updated a VMWARE esxi hypervisor to esxi 4.1. After the upgade, all the information in the datastore is missing. All the VM's and software in the datastore before the update is just missing. The Data store is mounted and is the correct size, it is just empty.

Help or any ideas would be greatly appreciated.

It would appear that it did not complete and upgrade, or a step was missed, and the installer has erased ALL your VMs.

1. Did it ask a question to preserve VMFS? (where your VMs are stored).

2. Have you checked and logged in via the console or ssh, and checked the datastore?

3. Is the datastore the same name?

It's possibly you could use the following and Recover.

http://www.diskinternals.com/vmfs-recovery/

It runs as a trial, and will detect if there are any VMDKs to recover, and then you can purchase.

4. Call Kroll Ontrack Data Recovery Specialists

5. Otherwise a Restore of your VMs are in order.
