Ltd. Lines: 45 Message-ID: <4rpmg8$1bv@minotaur.labyrinth.net.au> Reply-To: jbh@labyrinth.net.au NNTP-Posting-Host: portal-as2.labyrinth.net.au X-Newsreader: News for Windows NT X1.0-74 I have been trying to get a tandberg 4100 scsi tape drive running so far unsuccessfully. My configuration is: IBM 350/DX4-100 32 MB Adaptec 2940 SCSI controller, Fujitsu HD scsi 0 Matshita CD-ROM scsi 1 Tandberg TDC 4100 scsi 3 The tape is recognised at boot as follows: (ahc0:3:0): "TANDBERG TDC 4100 J04" Type 1 removeable SCSI 2 st(shc0:3:0): Sequential-Access density code 0x0, 512-byte blocks all operations done on the tape drive result in the following type of message: st0(ahc0:3:0): ILLEGAL REQUEST csi:0,8,0,0 asc:24,0 Invalid field in CDB field replacement unit: 2 st0: Cannot set selected mode st0: oops not queued I have tried a number of suggestions all of which fail with the same codes: these include: mt -f /dev/st0ctl.0 density 0x11 mt -f /dev/st0ctl.0 blocksize 512 It has been suggested that the firmware version is the problem, however the unit works fine with Windows NT and DOS tar for ASPI. I have recompiled the kernel with the SCSIDEBUG option on, but all the scsi commands produce a simillar error: scsi -f /dev/rst0 -d 0x10 produces: st0(ahc0:3:0): ILLEGAL REQUEST csi ..... I have read many articles in the various archives reporting simillar problems but no statement of the solution. One suggestion was to "just set the tape to SCSI-1 mode". How is this done? I have tried with the tape in during boot and out, it makes no difference. Can some witch doctor please advise or provide further suggestions for how to de-hex my cursed tape unit ;-) .
