Question Title Vmware VM import Failed to open disk scsi0:0:
This error comes when thin provisioned VMDK file is imported as new vm from backup, or clone VM.

Error : " Failed to open disk scsi0:0: Unsupported and/or invalid disk type 7. Did you forget to import the disk first?Unable to create virtual SCSI device for scsi0:0,  Module DevicePowerOn power on failed."

Solution : Reimport the VM using the "zeroedthick"

For doing this.....

Go to /vmfs/volumes/yourdatastore/

and then give the following command

vmkfstools -i Ubuntu-server.vmdk -d zeroedthick Ubuntu-server1.vmdk

after that remove Ubuntu-server.vmdk and rename Ubuntu-Server1.vmdk to Ubuntu-Server.vmdk and continue the process of import it will work.

"zeroedthink" a flat file of full size is created. ( not thin provisioned)
