9.3 Installing and Configuring a Tape Drive
Externaltape drives are 'installed' simplyby connecting them to the parallel, SCSI, USB, or FireWire port, asappropriate, and connecting power, although you may have to setjumpers to configure a SCSI drive for the proper SCSI ID andtermination. Internal tape drives are 3.5- or 5.25-inch half-heightdevices, and require the same physical installation steps as anyother externally accessible drive. The exact configuration stepsrequired differ between ATAPI and SCSI interfaces, as described inthe following sections.
|
9.3.1 Installing and Configuring an ATAPI Tape Drive
ATAPI tape drives are physicallyinstalled and configured just like any other ATAPI/IDE device: setthe drive's Master/Slave jumper; secure the drive inan available drive bay using four screws; connect the data cable,aligning Pin 1 on the drive connector with the colored stripe on thecable; and connect the power cable. Note the following issues wheninstalling an ATAPI tape drive:
Installing a tape drive on the same IDE channel as a hard disk risksdata corruption. If the system has one hard disk, install it as thePrimary Master and the tape drive on the Secondary channel. If thesystem has two hard disks, install both on the Primary channel, andinstall the tape drive on the Secondary channel. Do not install threeATA hard disks in a system with an ATAPI tape drive. If the systemhas an ATAPI CD-ROM drive, make that drive Secondary Master and thetape drive Secondary Slave. If the system has no ATAPI CD-ROM drive,make the tape drive Secondary Master.
Some tape drives have configuration jumpers to enable such things ashardware compression, read-while-write, DMA/PIO mode, and emulationmode. If your drive has one or more of these jumpers, set them asfollows:
- Hardware compression
Ordinarily, enable this option to allow the drive itself to compressthe data stream before recording it to tape, but note that softwarecompression is sometimes more efficient than hardware compression. Ifyou enable hardware compression, disable compression in your backuputility. Leaving both enabled results in'churning' that can actuallyincrease the size of the data being written to tape. Some backuputilities have a configuration checkbox that allows you to selecthardware compression. We've never been entirely sureof the purpose of this checkbox because hardware compression is (orshould be) transparent to the backup application, but if your backuputility has such a checkbox, it's probably a goodidea to mark it if you enable hardware compression on the drive.
Although different drive models from a particular manufacturer maysupposedly use compatible hardware compression, any tape made withhardware compression enabled may be unreadable except in the drivethat wrote it. There is no guarantee that you will be able to read ahardware-compressed tape made on one drive with any other drive.Something as subtle as a minor difference in firmware revision mayprevent reading a compressed tape even in a seemingly identicaldrive.
- Read-while-write
If your drive has a jumper to enable read-while-write, doing soallows the drive to use its separate read head to read and verifydata immediately after it is written, avoiding the need for atime-consuming second compare pass. Not all backup software supportsthis function. If your backup software does support it, you may needto enable support for it within the backup program.
- DMA/PIO mode
DMA mode increases throughput and reduces CPU utilization, but notall tape drives can operate in DMA mode. If your drive isDMA-capable, it may have a jumper to configure the drive for DMA modeversus PIO mode. In general, if the tape drive is the only device onthe ATA channel, or if the other device on that channel is alsoDMA-capable, enable DMA mode for the tape drive and enable DMAsupport for that channel in the operating system. If the tape driveshares the channel with a PIO-only device (e.g., an older CD-ROMdrive), disable DMA mode for the tape drive or (better) replace theother device with a DMA-capable device.
- Emulation mode
Some tape drives can emulate other drives via a jumper setting thatcauses the drive to return incorrect identification data to theoperating system. For example, we have an old Tecmar Travan NS20 tapedrive that was jumpered by default to identify itself as a WangtekModel 51000. Removing this jumper causes the drive to identify itselfas a Tecmar Travan NS20. Using emulation allows a new drive model tobe used with older software that does not support the new model. Setthis jumper, if present, according to themanufacturer's instructions.
Recent BIOSes allow setting boot sequence to first attempt bootingfrom a CD-ROM drive. What this actually tells the system is to bootfrom the first ATAPI device. If an ATAPI tape drive is configured asMaster (even on the Secondary channel), a system so configured mayattempt to boot from the tape drive, which causes the system to hang.You can avoid this problem by setting the CD-ROM drive to SecondaryMaster and the tape drive to Secondary Slave. This problem may alsooccur if the tape drive is the only device on the Secondary channel,whether it is configured as Master or Slave. If you cannot correctthe configuration or disable CD-ROM boot in BIOS, boot the systemwith no tape in the drive.
9.3.2 Installing and Configuring a SCSI Tape Drive
Installing and configuring a SCSItape drive is a bit more complicated than installing an ATAPI model.Rather than attempting to provide step-by-step instructions, whichvary according to the specific drive and adapter,we've chosen to illustrate a typical installationusing a Seagate Hornet NS20 drive and an Adaptec 2930 SCSI hostadapter, both representative selections.
If you have not already done so, install the SCSI host adapter. To doso, power down the system, remove the cover, and locate an availablebus-mastering PCI slot. (Some older systems don'tsupport bus mastering on all slots. Bus-mastering slots are usuallywhite or ivory; non-bus-mastering slots are brown or black.) Removethe slot cover for the selected slot, align the bus connector withthe slot, and press down firmly to seat the adapter. Use the screwthat secured the slot cover to secure the adapter. If you have aspare drive activity indicator LED, connect it to J2 on the hostadapter to indicate SCSI bus activity.
The Adaptec host adapter supports SCAM(SCSI Configured Auto-Magically)—a kind ofPlug and Play for SCSI that automatically configures SCSI ID andtermination. (SCAM is described in Section 10.4).Like most tape drives, the Seagate Travan NS20 does not support SCAM,so we'll have to set jumpers manually to assign SCSIID and set termination.
Like most manually configured SCSI devices, the Seagate Travan NS20drive has three jumpers—ID0 (SCSI ID 1), ID1 (SCSI ID 2), andID2 (SCSI ID 4). Installing jumper blocks on zero or more of thesejumpers allows you to set SCSI IDs 0 through 7. Connecting no jumpersassigns SCSI ID 0. Connecting one jumper assigns the SCSI IDassociated with that jumper (e.g., ID1 assigns SCSI ID 2). Connectingtwo jumpers assigns the SCSI ID that is the sum of the two jumpers(e.g., ID0 and ID2 sums the SCSI IDs 1 and 4 to assign the SCSI ID5). Connecting all three jumpers assigns SCSI ID 7. Like most SCSItape drives that require the SCSI ID to be assigned manually, theSeagate Travan NS20 drive by default is jumpered to SCSI ID 4, whichis usually not in use by other devices.
Avoid setting a tape drive to SCSI ID 0, 1, or 7. ID 0 is reserved byconvention for a bootable hard drive, ID 1 for a second hard drive,and ID 7 for the host adapter.
TheSeagate Travan NS20 drive also requires setting termination manually.Exactly two devices must be terminated on each SCSI bus, and thesedevices must be those at each end of the bus, as follows:
If the SCSI adapter has only internaldevices attached to it, the adapter itself and the final device onthe internal SCSI chain must be terminated.
If the SCSI adapter has only externaldevices attached to it, the adapter itself and the final device onthe external SCSI chain must be terminated.
If the SCSI adapter has both internal andexternal devices attached to it, the adapter must not be terminated.Instead, terminate the final internal device and the final externaldevice attached to the SCSI chain.
In this case, the Seagate tape drive is the final device on theinternal SCSI chain, which has no external devices, so the drive andthe host adapter must both be terminated. By default, Pins 3 and 4 onthe drive are jumpered, which terminates it. That'sthe correct setting, so we leave it as is. If we were installing theSeagate Travan NS20 between two existing SCSI devices,we'd remove the jumper from Pins 3 and 4 to disabletermination.
Pins 1 and 2 are also jumpered by default,which enables Termination Power. Again, that's thecorrect setting, so we leave it at default. Pins 5/6 and 7/8 arereserved on this drive, so we leave them unjumpered, which is thedefault. Pins 9/10 are jumpered, which enables Parity Checking.Again, that's the correct setting, so we leave it atdefault.

Adaptec hostadapters, which we use and recommend exclusively, by defaultautomatically detect terminated SCSI devices on the bus and set theirown termination status accordingly, so no further action is requiredto configure the drive properly. Note that a few internal SCSI cableshave a built-in terminator at the end of the cable. If you use such acable, make sure that termination is disabled on all drives connectedto that cable.
Once you haveresolved SCSI ID and termination issues and have the drive physicallyinstalled, the next step is to connect the cables. Most adapters aresupplied with a standard two-device cable. If you need to connectmore than two drives, replace the cable before proceeding. Otherwise,connect the cable to each drive, making sure to align Pin 1 on thecable (indicated by a red stripe) with Pin 1 on each device(indicated by a small number, triangle, or dot on the connector). ForSCSI IDs, it doesn't matter which drive connects towhich cable position, so mix and match drives and cable positions inwhatever way makes it easiest to route the cable. Just make sure thatthe physical last drive on the cable is the onethat's terminated. Connect the power cable.
After verifying all settings andconnections, turn on any external SCSI device(s) first, and then turnon the PC. Ordinarily, the system should boot normally, but the SCSItape drive may or may not be recognized, depending on the driveitself, your operating system, and other factors. Before youconfigure the operating system to use the drive, some systems mayrequire one or both of the following steps:
- CMOS Setup
On most systems, the PCI bus assigns IRQs and port addressesautomatically. If your system requires setting PCI bus parametersmanually, do so during the first restart, using the system ormotherboard documentation for guidance. (If your system BIOS iscapable of assigning IRQs automatically, there will usually be a CMOSSetup option worded something like 'Plug and PlayOS?' If that option is set to No, the PC BIOSassigns IRQs. If it is set to Yes, the BIOS allows the Plug and Playcapable OS [Windows 9X/2000/XP/Linux] to assign IRQs).
- SCSI Setup
At boot time, the SCSI BIOS displays adapter and BIOS information anda list of installed SCSI devices. Ordinarily, the default settingsare fine, but in some cases you may need to change settings to getthe drive to work at all or to optimize its performance. If this isthe case for your system, press whatever key sequence is needed toinvoke the SCSI Setup routine and make the necessary changes, asrecommended by the documentation for the host adapter and/or drive.
If either or both of these steps are needed, restart the system aftercompleting each. After you complete these steps, the system shouldboot normally and physically recognize the tape drive.
9.3.3 Configuring Windows 9X/2000/XP to Support a Tape Drive
Windows 9X/2000/XP does not supportany tape drives in the usual sense, although itmay or may not recognize and display the name of an installed tapedrive, depending on the drive and the version of Windows. Unlike mostother devices, for which drivers are readily available and can beinstalled using the Add New Hardware Wizard, tape drives runningunder Windows depend on device support built into the backupapplication itself. This is why, for example, the Windows 98Microsoft Backup applet—an OEM version of Veritas BackupExec—can use some tape drives and not others: the programitself contains drivers for the supported tape drives. All thisreally means is that you can't use unsupporteddrives with the built-in backup applet. That's notusually a problem because most tape drives are bundled with backupsoftware considerably superior to the Windows Backup applet.

Recent versions of third-partyWindows backup applications include drivers for many recent-modeltape drives. Most tape drives bundle a competent backuputility—often a special version of Backup Exec orARCserve—that contains the necessary drivers to support thatdrive under the operating systems intended to run them. You may,however, need to download drivers for a new tape drive either fromthe tape drive manufacturer (most of which do not supply drivers) orfrom the backup software company, if one of the following is true:
You have a previouslypurchased backup utility that does not contain drivers for the newdrive.
You have a backup utilityyou want to continue to use that was originally bundled with a driveyou are replacing, and that backup utility has no support for the newdrive.
The backup applicationsupplied with the new drive does not support the operating system youare using.
Before youpurchase a tape drive for use with Windows, verify that the backupapplication you intend to use has drivers for that tape drive.
9.3.4 Configuring Linux to Support a Tape Drive
The ease of configuringLinux to support a tape drive depends on the Linux distribution andversion, the type of drive, the interface it uses, and whether thedrive is present when Linux is installed or is added later. If youuse a modern, mainstream ATAPI or SCSI drive with a recent Linuxdistribution, installation will likely be straightforward. If you usean older distribution, an obsolescent or proprietary drive, or adrive that uses an interface other than ATAPI or SCSI, you mayencounter significant problems getting the drive to work, if indeedyou can get it working at all. You can use the following tape driveswith Linux:
Recent Linux releases natively support a wide variety of Travan, DDS,and AIT tape drives with ATAPI or SCSI interfaces. If you install andconfigure the drive and interface properly before you install Linux,the Linux installer will likely recognize the drive and automaticallyconfigure Linux to use it. In fact, Linux often does a better jobthan Windows 2000/XP of recognizing and configuring Travan, DDS, andAIT tape drives.
If you install a tape drive in a system with Linux already installed,log in as root and run the hardware detection utility (e.g., Kudzu inRedhat or Mandrake and Discover in Debian). If the drive issupported, the utility detects the drive, installs drivers, andautomatically configures Linux to use the drive. If the drive is notrecognized, check the web sites for the drive and your Linux distroto determine how to configure the drive manually.

Linux support for OnStream tape drives differs according to thecommand set used by the drive. All second-generation(ADR2) drives and first-generation (ADR)ADR30, ADR50, and ADR50e SCSI drives use the standard SCSI commandset, so the standard st (SCSI tape) driversuffices to interface the drive to the backup application (the ATAPIADR2.60IDE drive requires both the ide-scsi andst drivers).
Most first-generation OnStream ADR drives—the DI30, DI30 FAST,DP30, USB30, SC30, SC30e, SC50, SC50e, and FW30—use aproprietary command set that optimizes those drives for storingstreaming video. That command set differs significantly from thestandard ATAPI and SCSI command sets, which means the standardst driver does not support these drives. Full (oreven partial) Linux support requires a kernel rebuild or variousworkarounds. Fortunately, a modified version of thest driver, called the osstdriver, is available. The osst driver interfacesstandard backup applications to the proprietary command set of olderADR drives.

Travan TR-3 and earlier QIC drives use the floppy drive controller(FDC) interface, either directly or in some cases via a parallel portconnection. These drives are now so old that most have been retired,but if for some reason you must use an FDC-based tape drive on aLinux system, you may be able to get it running usingftape. The ftape driversupports QIC-40, QIC-80, QIC-3010 (TR-2), QIC-3020 (TR-3), IomegaDitto 2GB, and Ditto Max drives. For more information aboutftape, see http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html_single/Ftape-HOWTO.html.

Once Linux recognizes a tape drive, you can usebundled Linux applications such as tar,mt, mtx,dump, restore, andcpio to write and read tapes in the drive. You canalso use full-featured backup applications such as BRU (http://www.tolisgroup.com/), Amanda(http://www.amanda.org/), andArkeia (http://www.arkeia.com/)to implement a formal backup program.
Here are someuseful sites that cover various aspects of using tape drives withLinux:
