The ability to hot plug or hot unplug storage makes it easier to manage the storage needs of a virtual machine without requiring downtime. Virtual machines without SCSI controllers must be shut down before you can add or remove storage.

Resolution

If you do not need to hot plug or hot unplug storage for this virtual machine, no action is required. Otherwise, shut down the virtual machine and add a SCSI controller to the configuration.

To use a SCSI controller to hot plug and hot unplug storage, the guest operating system must be running the current version of integration services.
