■

 

The SCSI signal cable does not exceed the recommended length.

■

 

If multiple tape drives are installed, each drive has a unique SCSI ID.

Software

To prevent software failures, make sure the software is properly functioning:

■

 

The tape drive passes the Compaq Diagnostics Utility (Intel-based
computers only) test.

■

 

The controller has been configured using the Compaq System
Configuration Utility (Intel-based computers only.)

■

 

The adapter has been configured using the SRM console or AlphaBios
(AlphaServers only.)

■

 

The correct software drivers are being used. (Make sure that the
operating system driver for the tape drive matches the drive type.)

■

 

The version of the tape drive software supports the tape hardware you
are using.

If the software problems meet the above conditions, try reinstalling the tape
drive software.
