I do all this, before I'm going to contact you! I use the Seagate DAT at both busses (see appended E-Mail below a AH2940 and a AH2940UW). The last test was the ST15150N disk and the Seagate DAT at the 2940 with a very short internal 50 pol ribbon cable. The disk terminates the bus as usual, termpower from bus is o.k. No external devices. No of the disks or the HP DAT at the same bus direct before the Seagate DAT ever have such a problem, even under heavy load. The SCB timeout only occures when disk and DAT are under 'heavy' load, i.e. backup onto the DAT with dump or some other backup software. Using the same configuration and the HP DAT as the destination runs without any problems!!! Again. I've checked all terminators, etc. several times, it's all o.k! Here are the configurations I've tested: ADIC : ADIC 1200 autochanger with build in HP 1533A DDS2 DAT StDAT : Seagate DDS2 DAT, Phyton 28388 (8000 Series) WangQIC: Wangtec ES5525 525MB QIC Tape drive The total cable lengthe never exceeds 2.5 meters!

Before I make an PR, I want to query you as an SCSI expert! I read some mails in the list, concerning SCB problems on Adaptec host adapters. The solution named are ofter termination check/problems. After changing from NCR815 cotroller to 2940U, I run into such trouble, too. I do some debuging and testing on my SCSI buses (2940UW with 2 ST32171UW+Pioneer DR466 CDROM and 2940U ST15150N+Seagate Python 28388 DAT+Wangtec ES5525+Adic Changer with HP1533). It's definitely NOT a termination problem, and only the Seagate DAT has these problems on both busses! If I use dump or some other tool with constant high data flow, I get the messages like this (both are from the Seagate DAT, st0 on the 2940U, st3 same on 2940UW): Jan 31 18:29:03 odie /kernel: st3(ahc1:4:0): SCB 0x7 - timed out in command phase, SCSISIGI == 0x84 Jan 31 18:29:06 odie /kernel: SEQADDR = 0x41 SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Jan 31 18:29:06 odie /kernel: st3(ahc1:4:0): abort message in message buffer Jan 31 18:29:06 odie /kernel: st3(ahc1:4:0): SCB 0x7 - timed out in command phase, SCSISIGI == 0x94 Jan 31 18:29:06 odie /kernel: SEQADDR = 0x41 SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Jan 31 18:29:06 odie /kernel: st3(ahc1:4:0): no longer in timeout And sometimes Jan 25 15:26:36 odie /kernel: SEQADDR = 0x41 SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Jan 25 15:26:36 odie /kernel: st0(ahc0:1:0): abort message in message buffer Jan 25 15:26:36 odie /kernel: st0(ahc0:1:0): SCB 0x1 - timed out in command phase, SCSISIGI == 0x94 Jan 25 15:26:36 odie /kernel: SEQADDR = 0x41 SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Jan 25 15:26:36 odie /kernel: st0(ahc0:1:0): no longer in timeout Jan 25 15:26:36 odie /kernel: ahc0: Issued Channel A Bus Reset. 4 SCBs aborted Jan 25 15:26:36 odie /kernel: sd0(ahc0:0:0): UNIT ATTENTION asc:29,0 Jan 25 15:26:36 odie /kernel: sd0(ahc0:0:0): Power on, reset, or bus device reset occurred field replaceable unit: 1 Jan 25 15:26:36 odie /kernel: , retries:3 Jan 25 15:26:36 odie /kernel: st0(ahc0:1:0): Target Busy I append my kernel config file. --==_Exmh_5296095340 Content-Type: text/plain ; name="ODIE"; charset=us-ascii Content-Description: ODIE Content-Disposition: attachment; filename="ODIE" # # ODIE kernel config file # machine "i386" cpu "I686_CPU" # aka Pentium Pro(tm) ident ODIE maxusers 16 config kernel root on sd1 # This allows you to actually store this configuration file into # the kernel binary itself, where it may be later read by saying: # strings /kernel | grep ^___ | sed -e 's/^___//' > MYKERNEL # options INCLUDE_CONFIG_FILE # Include this file in kernel # # Under some circumstances it is convenient to increase the defaults # for the maximum number of processes per user and the maximum number # of open files files per user.

The problem is with the disk geometry. The geometry for the drive should be 6311/4/175 (according to www.seagate.com). However, when I'm installing and get to the part where I'm to partition the drive, FreeBSD gives me a Warning: invalid geometry. FreeBSD detects a 6313/4/175 geometry and says it is using a "more likely geometry, which is something like 240/240/175 and proceeds with the install. However, this geometry doesn't seem to work as I get page faults and the system crashes. I've tried to use the (G) command to reset the geometry to 6311/4/175, but the install program says that is incorrect also. I'm curious, when the install program "detects" the geometry, is it getting it right from the hard disk or from the SCSI controller BIOS? I've played around with some of the options concerning disk geometry in the SCSI controller BIOS and FreeBSD still says the geometry is 6313/4/175. And yes, I have set the CMOS BIOS to have "none" hard disks. What do I have to do to get this to work? Is the disk defective? Both the disk and controller are still under warrenty against defects, so sending either one back for replacement is not a problem. :) I was looking at the (A) option for partitioning the whole disk for FreeBSD. Would that eliminate the page faults? The machine is to be a server, so I plan to only have FreeBSD on it. Any assistance on this would be greatly appreciated.

Netware 4.1) The first year or so of production of ST-410800N's (hmm: I don't think that number is quote right, ST418000N maybe? ST4108000N?) we had saw 100% failure rate. Eventually the replacements held up. Not sure it was the only change but I think the good drives have firmware 0025. The failure mode was the drive was dead if power was interupted in service. No bad blocks or anything like that, just nothing on the SCSI bus. We became terrified of turning them off. Once running they were fine. You know that is a monster 5-1/4" drive? Needs lots of cooling and power. IMHO you would be better off with either an ST19171W or IBM DCHS09. Street prices have plumetted to under $800. IBM DCAS 34330 drives are around $300 (only 4G) but are faster than many 7200 RPM drives and quieter than anything. Two of those would be better and cheaper than one 9G drive. Maybe not total less power than a 9G. With the IBM DCHS09 watch out because the same drive was sold in Ultra and Fast versions. Probably you would rather have Ultra. I think the DCAS drive was only sold in Ultra. A couple of ST19171W's arrived at work this week. $799 each from http://www.insight.com and each included an internal wide SCSI cable. Now we have about 25 of them. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
