Environment

VMware vSphere ESXi 5.5
VMware vSphere ESXi 5.1

Cause

This issue occurs because the ddb.adapterType in the disk descriptor (vmdk) file has been modified with a value other than lsilogic.

Resolution

This is a known issue affecting VMware ESXi 5.x and 6.0.x.

Currently, there is no resolution.

To work around this issue, ensure that the ddb.adapterType on the descriptor (.vmdk) file is configured for lsilogic.

1. Log in as root to one of the ESXi host that has access to the datastore where the virtual disk(s) resides on.
2. Navigate to the virtual machine directory.
   
   Note: Ensure to create a backup of the descriptor (.vmdk) file before proceeding with the next steps.
   
   
3. Edit the descriptor (.vmdk) file. For more information, see Editing files on an ESX host using vi or nano (1020302).
4. Replace the value of ddb.adapterType with lsilogic.
   
   For example:
   
   ddb.adapterType = "lsilogic"
   
   
5. Save the file.
6. Reboot the virtual machine, If rebooting is not an option, migrate the virtual machine to another ESXi host.
