vold Provides Awareness of Hot-Plugged USB Devices

Solaris 10 1/06: The removable media manager (vold) is now hotplug aware. There is no need to restart this daemon to mount a USB mass storage device that has been hot-inserted. However, for some devices, it might still be necessary to manually mount the devices as vold is not always successful. In the case where vold fails to automatically mount a USB device, stop vold, like this:

# /etc/init.d/volmgt stop

For information about manually mounting a USB mass storage device, see How to Mount or Unmount a USB Mass Storage Device Without vold Running.
