Change the SCSI Bus Sharing Configuration in the vSphere Web Client

Procedure

1. Right-click a virtual machine in the inventory and select Edit Settings.
2. On the Virtual Hardware tab, expand SCSI controller, and select the type of sharing in the SCSI Bus Sharing drop-down menu.

   Option	Description
   None	Virtual disks cannot be shared by other virtual machines.
   Virtual	Virtual disks can be shared by virtual machines on the same ESXi host.
   Physical	Virtual disks can be shared by virtual machines on any ESXi host.

   For virtual or physical bus sharing, select Thick provision eager zeroed when you create the disk.
3. Click OK.
