Monitoring Tape Drive Status
You can monitor the status of the tape drives in several ways:
Reading the status lights on the front of the drive
Viewing the library’s Drive Display screens
Viewing the library’s Drive Status screens
Reading the Tape Drive LED Indicators
The meaning of the status lights differ between the AIT-2 and AIT-3 tape drives. Both are illustrated and
explained below.
