I have an adaptec internal wide cable with active termination and the bus looks like this: a: ahc3940UW, xp34300W, xp34300W, narrow nec cdrom, active term. b: (no devices) I was thinking that with the active terminator on the cable I could safely leave the narrow CD player at the end. Anyways, I have two questions: When the system boots, I see this boot message while the unused B channel of the 3940 is probed: ahc1 rev 0 int a irq 10 on pci1:5 ahc1: aic7880 Wide Channel B, SCSI Id=7, 16 SCBs ahc1 waiting for scsi devices to settle ahc1: Someone reset channel A ^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^ ??? The second and more worriesome question has to do with what happened last night when Amanda started reading the disks during backup. After all of the scanning work, Amanda did a small level 1 backup of a small partition, during which I got this: opus /kernel: Queue Full opus /kernel: sd1(ahc0:1:0): timed out in datain phase, SCSISIGI == 0x44 opus /kernel: SEQADDR == 0x5a opus /kernel: sd0(ahc0:0:0): abort message in message buffer opus /kernel: sd0(ahc0:0:0): timed out in datain phase, SCSISIGI == 0x54 opus /kernel: SEQADDR == 0x5a opus /kernel: ahc0: Issued Channel A Bus Reset. 2 SCBs aborted opus /kernel: sd1(ahc0:1:0): UNIT ATTENTION asc:29,2 opus /kernel: , retries:3 opus /kernel: sd0(ahc0:0:0): UNIT ATTENTION asc:29,2 opus /kernel: , retries:3 I have lots of 3940's and atlas-II drives, including another releng_2_2 system that have never ever burped, so I am assuming this problem has to do with my termination scheme (which seemed like a good idea at the time with that big wide terminator coming after the narrow CD player.) Comments? (other than gassing up the LART or whatever :) -Chris
