Troubleshooting: Dell PowerVault 110T DLT VS160 Tape Drive User's Guide 2. Make sure an active LVD/SE terminator is in place on the SCSI ribbon cable for the internal drive. The SCSI bus might be improperly terminated. 1. If the PowerVault 110T DLT VS160 Tape drive is the last or only device on the SCSI bus, make sure the drive is properly terminated. 2. If the PowerVault 110T DLT VS160 Tape drive is not the last or only device on the SCSI bus, check all SCSI cable connections and make sure the last device on the SCSI bus is terminated. 3. Make sure termination is set properly on the SCSI host adapter. 4. If you attach the drive to a narrow (50-pin) SCSI bus, you must use a customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled "high-byte termination." 5. Regardless of which device is used to terminate the SCSI bus, it must have power applied and be turned on for proper termination to occur. The SCSI terminator might not be at the end of the SCSI bus or more than two terminators might be present on the SCSI bus. Make sure the terminators are placed only at each end of the SCSI bus - normally one at the host adapter and one on the last device on the bus. However, if both internal and external devices are attached to the same SCSI host adapter, the adapter may be positioned in the middle of the SCSI bus and should not be terminated. In that case, the SCSI devices on each end of the bus must be terminated. The SCSI host adapter might be in Move the SCSI host adapter to a different expansion slot. a defective expansion slot. The SCSI bus might be too long. Make sure the total length of the SCSI bus does not exceed the ANSI SCSI standard of 19 feet (6 meters) for a Single-Ended (SE) bus, 40 feet (12 meters) for a Low-Voltage Differential (LVD) SCSI bus with multiple devices, or 82 feet (25 meters) for an LVD SCSI bus with a single device. If you attach the drive to an SE bus or if there are any SE devices attached to the bus, the bus is limited to the maximum cable lengths of an SE bus. There are fatal or nonfatal errors for which you cannot find the cause. The SCSI bus might be improperly terminated. 1. If the PowerVault 110T DLT VS160 Tape drive is the last or only device on the SCSI bus, make sure the drive is properly terminated. Make sure only the last device is terminated. 2. If the PowerVault 110T DLT VS160 Tape drive is not the last or only device on the SCSI bus, check all SCSI cable connections and make sure the last device on the SCSI bus is terminated. 3. Make sure termination is set properly on the SCSI host adapter. 4. If you attach the drive to a narrow (50-pin) SCSI bus, you must use a customer-supplied 68-pin to 50-pin adapter that terminates the unused 18 pins. These adapters are sometimes labeled "high-byte termination." 5. Regardless of which device is used to terminate the SCSI bus, it must have power applied and be turned on for proper termination to occur. The AC power source may not be properly grounded (PowerVault 110T DLT VS160 Tape External drive only). 1. Plug the PowerVault 110T DLT VS160 Tape External drive's power cable into a power outlet on the same circuit as the host server. 2. Plug the PowerVault 110T DLT VS160 Tape External drive's power cable into a different power outlet. The backup Application not compatible or application does improper device drivers installed. If the operating system recognizes the drive, but not the backup application, confirm that you are using a compatible backup file:///C|/Users/rishi_sood/Desktop/Temp/MissingDocsPosted/110t_dlt/UG/trouble.htm[3/8/2013 11:46:14 AM]
