hello! After many hours of testing with a good friend we didn't work out any solution for my problem - he recommended asking you, because you are the cracks that wrote the driver :-)) Well... something about my hardware first... i'm running an x86 system, powered with a gigabyte (GA-7VTXE+) board and an Athlon XP 1500+ CPU. There are four SCSI devices connected via a Dawicontrol DC-2945U hostadapter (symbios 53C875 chipset). The device list is as follows: murphy# camcontrol devlist -v scbus0 on sym0 bus 0: <IBM DDRS-34560 S97B> at scbus0 target 0 lun 0 (pass0,da0) <FUJITSU MAB3091S SUN9.0G 1806> at scbus0 target 1 lun 0 (pass1) <IBM DDRS34560SUN4.2G S98E> at scbus0 target 2 lun 0 (pass2) <TOSHIBA CD-ROM XM-6401TA 1009> at scbus0 target 4 lun 0 (pass3,cd0) < > at scbus0 target -1 lun -1 () scbus-1 on xpt0 bus 0: < > at scbus-1 target -1 lun -1 (xpt0) Target 0 is an SCSI-2 harddisk, and the targets 1 and 2 are SCA disks, plugged in with some SCA-SCSI-2 adapter. The main disk (target 0) is working: da0 at sym0 bus 0 target 0 lun 0 da0: <IBM DDRS-34560 S97B> Fixed Direct Access SCSI-2 device da0: 20.000MB/s transfers (20.000MHz, offset 15), Tagged Queueing Enabled da0: 4357MB (8925000 512 byte sectors: 255H 63S/T 555C) But the two other disks show up these errors: sym0: SCSI parity error detected: SCR1=1 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=3 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=1 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=3 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=1 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=3 DBC=11000000 SBCL=29 sym0: SCSI parity error detected: SCR1=1 DBC=11000000 SBCL=29 (da1:sym0:0:1:0): got CAM status 0x50 (da1:sym0:0:1:0): fatal error, failed to attach to device (da1:sym0:0:1:0): lost device (da1:sym0:0:1:0): removing device entry (da2:sym0:0:2:0): got CAM status 0x50 (da2:sym0:0:2:0): fatal error, failed to attach to device (da2:sym0:0:2:0): lost device (da2:sym0:0:2:0): removing device entry Since i used to have an adaptec 1542cf before, i'm quite sure that the disks and the SCA adapters are ok, because the system was running fine with the old card (yes, i know it's a shame to run fast SCA disks with this setting, but i got them really cheap :). After switching to the new motherboard, the old adaptec was unusable because it was an ISA card (new board only supports PCI). The CDROM was the last device in the chain and was terminating. I have changed this now, and have terminated the chain with an active terminator at the end of the SCSI cable. But, the errors keep showing up and the devices are not useable. Can you perhaps give me any hints on that problem? -- Fachbegriffe der Informatik einfach erklaert, Teil 6: "Globale Variable" == "Parameteruebergabemechanismus in 4GLs" (Marit Koehntopp) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
