hello, world\n I bought me a brand new shiny IBM DDYS-T18350N Ultra160LVD drive. My host adapter at this time does not support U160 SCSI, it's an ASUS P2L97S with on-board SCSI provided by an Adaptec AIC 7880. My understanding however is that the U160 drive will adapt to the slower bus (I may well be doing something silly here...) , which it apparently does (snippet from dmesg): da2 at ahc0 bus 0 target 12 lun 0 da2: <IBM DDYS-T18350N S96H> Fixed Direct Access SCSI-3 device da2: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing Enabled da2: 17501MB (35843670 512 byte sectors: 255H 63S/T 2231C) da1 at ahc0 bus 0 target 8 lun 0 da1: <FUJITSU MAA3182SC 0106> Fixed Direct Access SCSI-2 device da1: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing Enabled da1: 17422MB (35680750 512 byte sectors: 255H 63S/T 2221C) da0 at ahc0 bus 0 target 2 lun 0 da0: <IBM DCAS-34330 S65A> Fixed Direct Access SCSI-2 device da0: 20.000MB/s transfers (20.000MHz, offset 15) da0: 4134MB (8467200 512 byte sectors: 255H 63S/T 527C) Unfortunately, with the new drive installed, I seem to have problems with another drive in the system, the IBM DCAS-34330. After a short time after boot (~1 min) I get the following: (da0:ahc0:0:2:0): SCB 0x1a - timed out in Data-out phase, SEQADDR == 0x77 STACK == 0x93, 0x18c, 0x15c, 0x0 SXFRCTL0 == 0xa0 SCB count = 30 QINFIFO entries: 25 10 29 22 27 16 3 24 4 1 7 6 5 14 15 2 18 28 Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 15 9 5 4 6 2 8 1 10 7 13 14 11 0 12 Pending list: 28 18 2 15 14 5 6 7 1 4 24 3 16 27 22 29 10 25 26 Kernel Free SCB list: 9 13 12 11 23 17 0 19 21 20 Untagged Q(2): 26 sg[0] - Addr 0x1b9a000 : Length 4096 sg[1] - Addr 0x1bdb000 : Length 3072 (da0:ahc0:0:2:0): BDR message in message buffer (da0:ahc0:0:2:0): SCB 0x1a - timed out in Data-out phase, SEQADDR == 0x76 STACK == 0x93, 0x18c, 0x15c, 0x0 SXFRCTL0 == 0xa0 SCB count = 30 QINFIFO entries: 25 10 29 22 27 16 3 24 4 1 7 6 5 14 15 2 18 28 Waiting Queue entries: Disconnected Queue entries: QOUTFIFO entries: Sequencer Free SCB List: 15 9 5 4 6 2 8 1 10 7 13 14 11 0 12 Pending list: 28 18 2 15 14 5 6 7 1 4 24 3 16 27 22 29 10 25 26 Kernel Free SCB list: 9 13 12 11 23 17 0 19 21 20 Untagged Q(2): 26 sg[0] - Addr 0x1b9a000 : Length 4096 sg[1] - Addr 0x1bdb000 : Length 3072 (da0:ahc0:0:2:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 19 SCBs aborted My cabling is aic7880(50pin)--cd1--cd0--da0(Terminated) aic7880(68pin)--da1--da2--ActiveTerminationPlug and the board manual says that aic7880(68pin) is always terminated. I've played around with the "Force Single Ended" jumper of the da2, but to no avail. Even with only one device on each bus I get timeouts about every minute on both cables, e.g. aic7880(50pin)--cd0(Terminated) aic7880(68pin)--DDYS:ID9--ActiveTerminationPlug When installing FreeBSD from a cd in cd0 every now and then: (da0:ahc0:0:9:0): SCB 0x43 - timed out in Data-In Phase, SEQADDR == 0x14 (da0:ahc0:0:9:0): BDR Message in Message Buffer (da0:ahc0:0:9:0): SCB 0x43 - timed out in Data-In Phase, SEQADDR == 0x15 (da0:ahc0:0:9:0): no longer in timeout, status = 34b Can anyone please clue me in what I am doing wrong or what else I can try to get all devices to work?
