LTO drives have an LED and a single-character display (SCD) which
provide information about the drive's operational status. These LEDs are
not visible when the drive is operating inside the library. Instead, the LED
state and SCD code information for each LTO drive in a partition can be
viewed using the Drive Details screen
If you think that a drive may be faulty, follow these steps:
1. Display the Drive Details screen for the drive you suspect is having
2. Refer to the following table to interpret the information on the Drive
