Setting this object to eInitializing causes file system
4 to be initialized. Reading this object indicates if
the file system is currently being initialized.
Additional information:
The hrDeviceIndex value for the mass storage
device is the same value that is used to index into the
FILE-SYSTEM sub-tree. Since this product supports
up to 3 mass storage devices, and since the hrDeviceIndex
for the mass storage devices will start at 2 if the mass
storage device is installed, the FILE-SYSTEM4-INITIALIZE-VOLUME
object will be the object that allows the mass storage device to be
initialized that is the 3rd device.
