Restarting failed devices

Sometimes you will need to restart a device that has, for some reason, failed to initialize properly. A
device may have stopped for any number of reasons, such as a power failure or a connecting cable
malfunction. Virtual devices on a network appear disabled if the network connection has failed.
When a device is not initialized, it appears with a yellow warning icon. Some devices may take some
time to initialize, during which the warning icon will continue to appear. If a device shows the warning
icon after it is initialized, press F5 to refresh the device display.
Devices with a yellow exclamation mark are not initialized
If there is some other problem with the device or the controller, the warning icon will not disappear. You
must identify and correct the problem yourself. Then you must restart both Data Protector Express and
the Data Protector Express service. When Data Protector Express restarts, it will initialize the device
driver again. Check the Devices view to see that the devices are now properly working and that they
no longer display the warning icon. Any duplicate or old devices that are offline can be deleted from
the Catalog view.
