Hi, happy BSD'ers ! I'm trying to use a Sun EXABYTE XL (EXB-850SLBANSH2) with an Adaptec AHA 2940 UW on a 2.1.5 Release box with no results. I first encountered boot problem due to the *default* "wide" negociation of the AHA (it crashed the host adapter), so I turned it off with the AHA bios utility and I was able to boot from the sd0 drive... I then enabled the SCSI debug option and recompiled the kernel, wich now shows : >ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs >ahc0 waiting for scsi devices to settle >(ahc0:0:0): "Quantum XP32150W L912" type 0 fixed SCSI 2 >sd0(ahc0:0:0): Direct-Access 2050MB (4199760 512 byte sectors) >ahc0:A:2: refuses WIDE negotiation. Using 8bit transfers >(ahc0:2:0): "PIONEER CD-ROM DR-124X 1.06" type 5 removable SCSI 2 >cd0(ahc0:2:0): CD-ROM >cd0(ahc0:2:0): NOT READY asc:3a,0 Medium not present >(ahc0:4:0): "EXABYTE EXB-8505SMBANSH2 0793" type 1 removable SCSI 2 >st0(ahc0:4:0): Sequential-Access density code 0x15, 1024-byte blocks, write-enabled >probe0(ahc0:9:0): scsi_cmd >probe0(ahc0:9:0): ahc_scsi_cmd >probe0(ahc0:9:0): ahc_done >probe0(ahc0:9:0): scsi_done >(ahc0:9:0): command: 0,0,0,0,0,0-[0 bytes] >probe0(ahc0:9:0): scsi_cmd >probe0(ahc0:9:0): ahc_scsi_cmd >probe0(ahc0:9:0): ahc_done >probe0(ahc0:9:0): scsi_done >(ahc0:9:0): command: 12,0,0,0,2c,0-[44 bytes] >------------------------------ >000: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >016: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 >032: 00 00 00 00 00 00 00 00 00 00 00 00 >------------------------------ > So I made the rst0 device (sh MAKEDEV st0) and tried a simple "tar cvf /dev/rst0 /etc" i get the message "st0 (ahc0:4:0) Target Busy". It seems that if the data takes too long time to be proceced, either the Exabyte does an unexpected error (??) or issue a SCSI reset... The first syslog message issued is about the disk (??) : /kernel sd0(ahc0:0:0) timed out in dataout phase SCSISIGI = 0x4 /kernel ahc0: issued channel A bus reset #2 . SCBs aborted /kernel sd0(ahc0:0:0) UNIT ATTENTION asc:29,2 /kernel , retries 3 /kernel st0(ahc0:4:0) UNIT ATTENTION asc:29:0 /kernel st0(ahc0:4:0) Power on, reset, or bus device rest occured /kernel st0(ahc0:4:0) Target Busy Has anyone clues ? Did any of you managed to make this kind of config work ?
