Only after the system was updated to 4.2-STABLE as of 2-18-2001 to fix the security vunerability in FreeBSD-SA-01:24 did this problem manifest itself. >How-To-Repeat: Install/run 4.2-STABLE (>11-18-2001) on a IFT-3102 RAID controller. At the start of filesystem mount kernel errors related to ahc SCB's. >Fix: Apply the following patch to /usr/src/sys/cam/cam_xpt.c which adds a quirk entry for the IFT-3102 to limit the number of tags to use to the controller default of 32 per host LUN: 84a385,396 > /* > * Infortrend IFT-3102 has a global host scsi channel > * configuration paramater that determines the maximum > * number of tags that each host lun (logical drive presented > * by the raid controller to the host controller) > * can handle. By default this is 32 tags per lun. > */ > { > { T_DIRECT, SIP_MEDIA_FIXED, "IFT", "3102", "*" }, > /*quirks*/0, /*mintags*/2, /*maxtags*/32 > }, > Another possible workaround is to try to increase the number of tags per host LUN to 255, but this might have other adverse affects on controller performance. I didn't test this as this controller handles 4 production systems with two different OSes (FreeBSD and NT) and I cannot risk stability problems on these other systems. >Release-Note: >Audit-Trail: >Unformatted: controller To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
