VMware: Windows 2008 disks are offline after upgrading hardware 4 to 7

Today I did some maintenance in the datacenter. I upgraded last month to vCenter 4.1 and the ESX hosts from 4.0 to 4.1. Today was planned to update some virtual hardware from 4 to 7 but after I upgraded and started some Windows 2008 SP2 VM’s I can’t connect mappings and receiving some errors from the loginscript. After some troubleshooting I saw that some local disks (.VMDK) are offline!

Solution:

Goto Disk Management > Right click on the offline disk, select: Online

Okay, the disk is online.. my data is back without any dataloss but my shares are gone. You only need to restart the VM again to resolve this issue.
