SCSI 160 Hard drive woes.

SCSI 160 Hard drive woes.

It just isn't my week.

I just upgraded the HD on my main server, (here is the info from the
logfiles

Mar  5 15:51:29 rascal /kernel: FreeBSD 4.0-RELEASE #0: Thu Sep 21 06:27:55
CDT 2000
.
Mar  5 15:51:30 rascal /kernel: ahc0: <Adaptec 19160B Ultra160 SCSI adapter>
port 0xec00-0xecff mem 0xd8000000-0xd8000fff irq 10 at device 10.0 on pci0
Mar  5 15:51:30 rascal /kernel: ahc0: aic7892 Wide Channel A, SCSI Id=7,
16/255 SCBs
.
Mar  5 15:51:31 rascal /kernel: da0 at ahc0 bus 0 target 0 lun 0
Mar  5 15:51:31 rascal /kernel: da0: <SEAGATE ST39204LW 0006> Fixed Direct
Access SCSI-3 device
Mar  5 15:51:31 rascal /kernel: da0: 80.000MB/s transfers (40.000MHz, offset
63, 16bit), Tagged Queueing Enabled
Mar  5 15:51:31 rascal /kernel: da0: 8750MB (17921835 512 byte sectors: 255H
63S/T 1115C)

Ever since upgrading the hard drive, and SCSI controller, this machine is
rebooting itself at least once per day.
There is no error messages being recorded in the log, so I am at a loss as
to what might be causing this problem.
If anyone can shed some light on this, it would be apprecieated.

I have found some information on using camcontrol to turn off WCE and
tagging.  It made no difference, the machine rebooted itself at 2:30am this
morning anyways.  I also found several references that this problem seems to
be associated uniquly with this hardware.

What recommendations do all you FreeBSD users have for something in a 9G
SCSI 160  that can acctually attain 160M transfers, and will work well with
FreeBSD (I still have time to return this drive and controller, and replace
it with something else.)

        I have a 29160 (in 32 bit mode) and 1x18GB IBM U2W drive and
   1x36GB IBM U160 drive. Since installing the controller, I had the
   machine up for 45 days, then installed more memory. Since it has
   been running for 9 days.

        I don't believe there is a disk out there, SCSI, ATA or
   otherwise, that will do 160MB transfers, except in burst mode,
   but only to the limit of its cache. Where you will get the 160MB
   is via groups of disks (or, I suppose, the proper format RAID)
   that can run the SCSI bus at 160MB or somewhat close.

1. Ultra 160 SCSI Hard Disk !

Hi there,

I have an Asus board with an adaptec SCSI host on it (aic7892)
And 2 HD Quantum Atlas IV Connected to the Ultra 160 port !

So, the SCSI bios are tune to match Ultra 160 devices...

But, when FreeBSD (4) start, in the /var/log/messages files, it's only
seems to config itself for a transfert of 80.000MB/s in the place of 160
MB/s

May I set this feature somewhere...Does it's support 160....??
Thanks in advance !
