Solution : Vmware VM import 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.

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)
