  • Page 143: Problems With Library Installation

    This chapter provides a list of suggestions for solving problems that may occur when you are installing and operating the library and the enclosed tape drives. The instructions in this chapter are basic troubleshooting guidelines. For more advanced troubleshooting, contact your service provider.
  • Page 144 If your library and application software are not communicating after installation, check the following: SCSI IDs. Make sure that the SCSI IDs you selected for the tape drives and library are not the same as the ID used by any other SCSI device on that bus, including the SCSI adapter card.
  • Page 145 Termination. Make sure your bus is properly terminated as described in Appendix B. If another SCSI device previously terminated the SCSI bus and is no longer at the physical end of the bus, be sure to remove the terminators from that device. Compatibility.
  • Page 146 If you have been successfully operating the application software and library in the past, but are now experiencing problems reading and writing data, check the following: Write-protect switch. If you are writing data, make sure the cartridge is write enabled (move the write-protect switch toward the edge of the cartridge).
  • Page 147 If the library has been successfully operating in the past, but is now experiencing problems, check the following: Control mode. If you are using an application software package to control CHM operations, the library must be set to SCSI Interface mode.

  • Page 155 This appendix provides an overview of the Small Computer System Interface 2 (SCSI-2) and gives an overview of how to configure the SCSI bus. SCSI is a standard specification that allows an application running on a host computer to communicate with peripheral SCSI devices, such as the library and the enclosed tape drives.
  • Page 156 The Scalar AIT 220 supports AIT tapes drives with wide SCSI configurations. The library supports AIT tapes drives with fast SCSI, which does not require any special cabling or configuration.
  • Page 157 Differential SCSI cable lengths. Make sure the total length of all internal and external cables on the SCSI bus does not exceed 82 feet (25.0 meters). If LVD devices are connected to the bus the total length of all internal and external cables on the SCSI bus does not exceed 41 feet (12.0 meters).
  • Page 158 If you have one tape drive installed, the library uses two SCSI IDs, one for the library itself and one for the tape drive. If you have two drives installed, the library uses three IDs. Separate IDs allow the library and tape drives to operate as independent devices, receiving different sets of SCSI commands from the host.
  • Page 159 This appendix describes the error codes that appear on the library’s LCD (liquid crystal display). LCD error codes do not reflect tape drive errors. For information about SCSI error conditions (sense data), refer to pages 97 and to the Scalar AIT 220 Library SCSI Reference.

  • Page 169 This appendix describes how you can operate the library in the sequential control mode: Sequential 1. When the library is operating in one of the sequential modes, its internal firmware instructs the CHM to move cartridges sequentially between the cartridge slots and one or both tape drives. No application software is required to support cartridge pick and place functions.
  • Page 170 In Sequential 1 mode, the library processes the cartridges in tape drive 1 (closest to the magazine). In Sequential 1 mode, the library performs the following steps: Picks the cartridge from slot 1 and places it in the tape drive specified by the mode (1 or 2).
  • Page 171 Depending on how the Loop option is set, either returns to the first cartridge and begins the process again, or stops. The Loop option is described on page 156. In the sequential mode, the tape drive specified by the mode must be installed;...
  • Page 172 Before restarting, the library performs the following actions: If the CHM was moving a cartridge, it finishes the move. (This includes inserting the cartridge into the tape drive if the CHM was moving a cartridge to a tape drive.) If you attempted to open the door, the library does not release the door interlock until it has completed the move.
  • Page 173 If you want to resume sequential processing from the first cartridge, select “Set Next Cart to 1” from the Sequential Options menu.
  • Page 174 Although the library has effective methods for resuming operation, it is best to avoid interruptions when the library is operating sequentially. In particular: S Do not reset or power cycle the library unless absolutely necessary. Reset the library only to clear certain error conditions and power off the library only to perform maintenance or to store it.
