Terminator. Check the terminator used on the tape drive. 

Both LTO-2 and LTO-3 SCSI tape drives are Ultra 160 SCSI devices and require 

a minimum Ultra 160 non-RAID SCSI card, Ultra 160 rated SCSI cabling, and 

an Ultra 3 Active SCSI terminator. Cabling and termination rated higher (Ultra 

320, for example) is also acceptable. 

An appropriate terminator is stamped with Ultra 3 or LVD 160 and “Active 

Negation.”

Your library was shipped with the appropriate terminator. If you incorporate 

the library into an existing setup that is not properly terminated, or if the 

original terminator is replaced during setup, you may experience the failures 

described below. 

Failure symptoms include:



Read/Write failure



Bus hangs



Connectivity issues—tape drive not seen on bus or drops off bus



Command failures—commands to this device may fail while commands to 

other devices on the bus may work properly

Your backup software may report an error as a result of a failure to 

communicate with the tape drive(s) or library, a failure by a tape drive to write 

or read data, or because of a software configuration issue. 

Communication problems on the SCSI bus may be reported by the backup 

application as resets, a loss of communication with a tape drive, failure to 

detect a tape drive, I/O device errors, or parity errors. These types of errors 

may occur intermittently. 



If you have a SCSI library, check the tape drive’s installation on the SCSI bus, 

described in 



If you have a Fibre Channel connection to your library (the tape drives 

installed in the library are Fibre Channel), check the Fibre Channel 

connection, described in 

.

Both LTO-2 and LTO-3 SCSI tape drives require an Ultra 3 or 

LVD 160 terminator to function properly on the SCSI bus. An 

inadequate terminator will result in various SCSI bus issues, 

including bus hangs and Read/Write failures.
