This error code is used when an OpenVMS system service fails with the status SS$_NOSUCHDEV or SS$_IVDEVNAM. This will typically occur in mrd_startup(3mrd) when the caller tries to open a device which doesn't exist or uses an invalid device name. This error also occurs when the routine is called on behalf of a device controlled by the JU driver. The Media Robot Utility no longer uses the JU driver.
