SCSI Issues
SCSI ID Not Recognized by Host Server
• Make sure that all SCSI devices on the same bus have unique ID numbers.
• If the SCSI bus is narrow (50-pin) only SCSI IDs 0 through 7 are available.
• Make sure that you cycle power on the library after changing the SCSI ID.
• Reboot the host server.
Device Not Detected on HVD SCSI Bus or HBA
• Attach the library to an LVD SCSI host adapter/bus.
• Check if the SCSI cable length has been exceeded. If so, use a shorter cable, or
remove other devices from the bus.
• Check for conflicting SCSI IDs.
• Check that the HBA supports multiple LUNs and that this feature is enabled.
• The library may not be properly terminated. See
Installation Issues
on page 62.
• Power on the library before powering on the host computer.
• Check that the device has been powered on and is not in an error state.
• Check the SCSI connector for bent pins.
