The SCSI ID must be unique for each device attached to the SCSI bus. To list the existing devices, use the following command: % hinv -v | grep SCSI This will produce output similar to the following: Integral SCSI controller 0: Version WD33C93B, revision D Disk drive: unit 1 in SCSI controller 0 In this, "unit X" indicates the SCSI ID. Review the list of existing SCSI IDs and choose an available ID to assign to your new tape drive. configuring the device files To install the HP Surestore drive on a Silicon Graphics system running IRIX, you will need to modify the kernel configuration file. If you want tar to default to short block transfers, change the 512*512 in your tpsc or scsi HP entry to 128*512 (128-kilobyte blocks) or, better still, 64*512 (64kilobyte blocks). 1Open the kernel configuration file /var/sysgen/master.d/scsi, for IRIX 6.2 and later, with a text editor. 2Find the following entry in the kernel configuration file and copy it to a new location in the file where you can edit it as appropriate for your tape drive: For IRIX 6.2: Ultrium tape drives {DATTAPE, TPDAT,2,7,"HP","Ultrium",0,0,{0}, MTCAN_BSF|MTCAN_BSR|MTCAN_APPEND|MTCAN_SETMK|MTCAN_PART| MTCAN_PREV|MTCAN_SYNC|MTCAN_SPEOD|MTCAN_CHKRDY|MTCAN_VAR| MTCAN_SETSZ|MTCAN_SILI|MTCAN_SEEK|MTCAN_CMTYPEANY|MTCAN_COMPRESS, /*minimum delay to I/O is 4 minutes, because when a retry is *performed, the drive retries a number of times, and then *rewinds to BOT, repositions, and tries again.*/ 40, 4*60, 20*60, 5*60, 512, 64*512, 0, (u_char*)0 }, DAT tape drives and autoloaders {DATTAPE,TPDAT,2,6,"HP","C----A",0,0,{0}, MTCAN_BSF|MTCAN_BSR|MTCAN_APPEND|MTCAN_SETMK|MTCAN_PART| MTCAN_PREV|MTCAN_SYNC|MTCAN_SPEOD|MTCAN_CHKRDY|MTCAN_VAR| MTCAN_SETSZ|MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY|MTCAN_COMPRESS, /*minimum delay to I/O is 4 minutes, because when a retry is *performed, the drive retries a number of times, and then *rewinds to BOT, repositions, and tries again.*/ 40, 4*60, 20*60, 5*60,512, 64*512, 0, (u_char*)0 }, Note: Change "C----A" in the first line to the appropriate value for your device.

When you reboot, the device files for the Ultrium drive will be created automatically. The following device files will be created in /dev/rmt: tps0d3 tps0d3c tps0d3cnr tps0d3cnrns tps0d3cnrnsv tps0d3cnrs tps0d3cnrsv tps0d3cnrv tps0d3cns tps0d3cnsv tps0d3cs tps0d3csv tps0d3cv tps0d3nr tps0d3nrns tps0d3nrnsv tps0d3nrs tps0d3nrsv tps0d3nrv tps0d3ns tps0d3nsv tps0d3s tps0d3sv tps0d3v tps0d3stat These device file names can be interpreted as follows: Device Name Function c Compression nr No rewind on close v Device supports variable block sizes ns Device does not byte-swap s Device does byte-swap stat Allows the device to be used when one of the other device files specifying the same physical device is already opened For example, the device file tps0d3 indicates a device on controller card 0 at SCSI ID 3, and the device file tps0d3nrv indicates a device on controller card 0 at SCSI ID 3 that does not rewind on close and supports variable block sizes. Once the device files have been created, you should confirm that your new tape drive is working properly. See Verifying Installation. MTCAN and constants values The MTCAN values have the following functions: MTCAN value Capability Enabled APPEND Append to existing tape data BSF Backspace file BSR Backspace record CHKRDY Determine if a tape cartridge is present CHTYPEANY Change density and/or fixed to variable at points other than beginning of tape COMPRESS Compression PART Multiple partitions PREV Prevent media removal SEEK Seek to a particular block SETMK Setmarks SETSZ Fixed block size can be set SILI Suppress illegal length indicators SPEOD Space to EOD (end of data) SYNC Synchronous mode SCSI VAR Variable block sizes The constants have the following functions: Constant 40 4*60 4*60 5*60 512 64*512 or 512*512 Description Transfer time-out in "inverse ticks" Minimum time-out in seconds for any command Space command time-out in seconds Time-out in seconds for long operations (such as rewinds) Default block size in bytes for fixed block size mode Recommended blocking factor in bytes for the upper limit of read/write commands © 2001, Hewlett-Packard Company file:///C|/Documents%20and%20Settings/topher.COL-SPRINGS/Desktop/dltvs80%20manual/document/common/unix/reseller/eng/c_silcon.htm [11/29/2001 8:34:29 AM]
