Earlier this week I posted a message to freebsd-hardware about SCSI errors using the NCR driver with both an 860 and 875 based controllers. Since the problem was identified, here is a followup. The problem with the NCR 875 card (JBond) was the card itself. After replacing the card with another one from the dealers inventory, the NCR driver was able to address all devices without difficulty. The only sensible conclusion about the 860 controller is that it is defective as well, just not to the point of failure. Both of the SCSI cards were JBond (www.jbond.com) which, IMHO, says something about their quality control. Thanks to those who resonded with suggestions and past experience. -- jmastrol@mcs.net #import <std_disclaimer.h> For public PGP Key 'finger jmastrol@mcs.net' -----Forwarded message from John Mastrolia <jmastrol@Mcs.Net>----- Date: Sat, 28 Mar 1998 23:04:19 -0600 From: John Mastrolia <jmastrol@Mcs.Net> To: freebsd-hardware@FreeBSD.ORG Subject: SCSI card difficulties X-Mailer: Mutt 0.84 X-Loop: FreeBSD.org I am getting a few error messages with my Symbios 53C860 based SCSI card that seem a bit unusual. First, I'm running FreeBSD 2.2.5-RELEASE on an asus P55T2P4 3.10 motherboard with an AMD K6-233. Devices include two Seagate ST31200N's, a DEC RZ26L, an External Zip (SCSI), a Plextor 12/20-PLEX cd-rom, and (the problem) an Exabyte 4200-c DAT tape drive. With the ncr 860 card the tape drive works as expected faithfully completing backups. The errors only occur on start up. Here's a snippit of dmesg: --- begin --- (ncr0:4:0): "EXABYTE EXB-4200c 149" type 1 removable SCSI 2 st0(ncr0:4:0): Sequential-Access ncr0: SCSI phase error fixup: CCB address misma tch (0xf0852400 != 0xf06a6400) np->ccb = 0xf06a6400 st0(ncr0:4:0): phase change 6-7 6@004bf5d8 resid=4. st0(ncr0:4:0): asynchronous. st0(ncr0:4:0): M_REJECT received (4:8). density code 0x13, drive empty --- end --- The device is setup to 5MB/sec with queue tags disabled, 8 bit width in the 860's setup. The machine is running flawlessly and I did not notice any problems until I made the mistake of upgrading the SCSI card to an NCR 53C875. The darn system would not boot until the tape was removed from the chain. I have the error messages if anyone is interested, but thought I would address these oddities with my narrow card before jumping further into the fire. Any suggestions or info appreciated. Thanks in advance. -- jmastrol@mcs.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message -----End of forwarded message----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
