Basic Library Operations

This chapter describes the overall menu structure of the Operator 
Control Panel (OCP). The following functions are described: 
• Library status
• Eject/unlock
• Load
• SCSI ID
• Mode
• Information 
• Code update
• Tests
Caution: Before executing a menu function command from the 
OCP, verify that there is no SCSI bus activity to the 
tape library or drives. Executing commands via the 
OCP and SCSI bus simultaneously may result in 
operation failure and/or drive unavailability.
