Installation ProblemsProblems encountered during the installation of the library are usually caused byimproper SCSI bus configuration, application software configuration errors, or anincorrectly configured operating system. If the application software that you areusing is not communicating with the library after installation, check the following:v Picker Ship Lock Key:Ensure that the Picker Ship Lock Key on the top cover has been removed beforepowering on the library.v Drive/Library SCSI or Loop ID:Ensure that the SCSI ID of the Drive/Library (or SAS or Fibre Channel Loop ID)is correct and not the same as other devices that may be on the same bus.v Host Bus Adapter (HBA) Compatibility:Ensure that the library is compatible with the HBA. For best performance, theHBA used for this library should be SCSI-3 LVDS. Pay particular attention toany steps describing settings of various jumpers and/or switches.v HBA LUN 0/1 Support:A single ID will address both drive and library since the drive is LUN 0 and thelibrary is LUN 1. These models require an HBA that supports LUN scanningwhich must be enabled at the HBA.v Cable Connections:Ensure that there are no bent pins on cables and that all connections are securelyfastened.v Fibre Channel Tape Support:Make sure that Fibre Channel Tape Support is enabled on the HBA if you areinstalling a library with a Fibre Channel drive.v SCSI Cable Length:Ensure that the maximum cable length is not over 25 meters (82 ft.) for a singledevice on the bus or 12 meters (40 ft.) for multiple devices. Internal SCSI lengthwithin the library accounts for 2 ft.v SCSI Termination:Verify proper termination on both ends of the SCSI bus.v Backup Application Installation:Refer to the documentation included with your backup application softwareinstructions on how to verify proper installation.v Device Driver Installation:Make sure that the proper device driver, if applicable, is installed for the library.Note: Many backup applications use their own drivers for the library and drive.Before installing a driver, make sure it will not be in conflict with thesoftware. Contact your Backup Application vendor for this information.Library Recovery Problem DeterminationThe 2U and 4U library firmware will generally retry failed operations up to threetimes before posting a failure to complete the operation, or, in some situations,proceeding with an operation that can be completed in an alternative manner. Ofcourse, if the operation is successful within the allotted retry count, the appropriateretry counter is updated and recorded in the retry log and the next libraryoperation will commence.7-6 Dell PowerVault TL2000 Tape Library and TL4000 Tape Library User's Guide
