Hardware Problems Table 2-12: Tape Drive Problems continued Problem Possible Cause DLT drive does not read tape (continued). Tape is not compatible with the drive. Server cannot see DLT drive. Device conflict exists. SCSI terminator is missing for the external DLT drive. DAT drive error is displayed. Error occurs during backup, but the backup is completed. Maximum number of drives per controller has been exceeded. Problem exists with a DAT drive. Non-failure error has occurred. Possible Solution Check your tape specifications to be sure that the tape is designed to work with the drive. Be sure that each device on the controller has a unique ID. Use the server setup utility to check for conflicts. The external DLT drive requires a SCSI terminator to be secured to the unused SCSI IN connector on the back of the drive. DLT drives can be daisy chained. Do not connect more than three units per SCSI controller. The last DLT drive in the chain requires the SCSI terminator. If the terminator is not connected, the system may not recognize the DLT drive. Refer to your controller documentation. Refer to "DAT Drives" in this chapter. Some errors do not cause a failure. If an error occurs but does not disrupt the backup, you may be able to ignore the error. Contact the software vendor for more information about the message. HP Servers Troubleshooting Guide 2-33
