Problem : Unsupported or invalid disk type 7. Ensure that the disk has been imported.
You can run into this problem when you try to power on virtual machine on Esxi that converted from physical to virtual machine. An error message prompt and running of vm will stop. The message looks something like :
Module DevicePowerOn power on failed. Unable to create virtual SCSI device for scsi0:0,
Failed to open disk scsi0:0:
Unsupported or invalid disk type 7. Ensure that the disk has been imported.
This problem occurs when you are converting physical machine to virtual one , actually the The VMs were converted and set to preserve the controller, which was IDE. The disks were also in sparse format. The VM would not boot because the controller was set to lsi sas which will not work with sparse disks. If this is changed then the VM will power up successfully.
Method 1 :
First up, open putty SSH session then type the following :
note that datastore1 is sample name , just type your datastore name , if you don't know what is it , just type "ls" after volumes you will see a folder in greeny color , it's the datastore name.
Then type :
mkfstools -i xxxxxx.vmdk xxxx-New.vmdk
note that xxxxx is disk name of the related virtual machine , the process will convert disk type to zerothick , if the process success try to run your machine , if its not successful the following message may appear :
Destination disk format: VMFS zeroedthick
Cloning disk 'DemoServer.E-Data.local-s001.vmdk'...
Failed to clone disk: There is not enough space on the file system for
the selected operation (13).
If it does appear, then move to method2 :
Method 2 :
You might need to create new virtual machine with IDE hard disk and SCSI controller , you need to edit vmx file and remove line of LSI logic SAS controller and add instead ide controller configuration :
ide0:0.present = "TRUE"
ide0:0.fileName = "xxxxx.vmdk"
ide0:1.present = "TRUE"
ide0:1.autodetect = "TRUE"
ide0:1.filename = "auto detect"
and under swap sections :
replay.filename = ""
ide0:0.redo = ""
then try to power on your machine.
In the future purposes when you are converting SAS Machine to virtual to avoid such case try to modify the machine configuration before you convert it never convert SAS disk to IDE on machine that have LSI Logic Card and SAS Disks , see the picture :
