I've searched all over (not totally exhaustive, but close) and can't find an answer that I thought would have come up before. Basically, I need to change the order that the kernel assigns drive names on bootup.
It all started out with an old Intel server board with NCR/Symbios scsi builton. I added a QLogic QLA2100 fibre controller and everything was fine except that it was a little slow and couldn't hold enough ram. I took another (newer) Intel server board and put it in the case. This board has an Adaptec AIC7896 builtin. My custom kernel didn't have the aic driver so I took the opportunity to upgrade to 7.0 and built a new kernel. Everything was fine until I turned on the external fibre chassis and found that my da0 became da7. The board is in a rack-mount case so I cant put the QLA into a different slot and the bios doesn't have any way to change irq settings on the pci slots. I my mind, the logical answer is to tell FBSD to scan ahc0 before isp0. Through all my searching through docs and the mailing list archives, I can't find any mention of how to do this. I did find one mention of turning off the bios on the offending scsi card (it was a system with 2 Adaptecs). Been there, tried that, didn't work. Feel free to slap my face and call me stupid as long as you point my to the proper info if I somehow missed it. Here are the relevant parts of dmesg if that helps (I didn't include the drives themselves since I can't get it boot with the external chassis turned on): FreeBSD 7.0-RELEASE #1: Mon Mar 17 14:43:04 EDT 2008 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/MYKERN Timecounter "i8254" frequency 1193182 Hz quality 0 CPU: Intel Pentium III (596.92-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x681 Stepping = 1 Features=0x383fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,MMX,FXSR,SSE> real memory = 2139029504 (2039 MB) avail memory = 2087882752 (1991 MB) ACPI APIC Table: <Intel N440BX > ioapic0 <Version 1.1> irqs 0-23 on motherboard kbd1 at kbdmux0 acpi0: <PTLTD RSDT> on motherboard acpi0: [ITHREAD] acpi0: Power Button (fixed) Timecounter "ACPI-safe" frequency 3579545 Hz quality 850 acpi_timer0: <24-bit timer at 3.579545MHz> port 0xc08-0xc0b on acpi0 cpu0: <ACPI CPU> on acpi0 pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0 agp0: <Intel 82443GX host to PCI bridge> on hostb0 pcib1: <PCI-PCI bridge> at device 1.0 on pci0 pci1: <PCI bus> on pcib1 pcib2: <PCI-PCI bridge> at device 15.0 on pci1 pci2: <PCI bus> on pcib2 isp0: <Qlogic ISP 2100 PCI FC-AL Adapter> port 0x2000-0x20ff mem 0xf4500000-0xf4500fff irq 19 at device 9.0 on pci0 firmware_get: failed to load firmware image isp_2100 isp0: [ITHREAD] isp0: Board Type 2100, Chip Revision 0x3, resident F/W Revision 1.15.21 pci0: <simple comms> at device 11.0 (no driver attached) ahc0: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0x2400-0x24ff mem 0xf4501000-0xf4501fff irq 19 at device 12.0 on pci0 ahc0: [ITHREAD] aic7896/97: Ultra2 Wide Channel A, SCSI Id=7, 32/253 SCBs ahc1: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0x2800-0x28ff mem 0xf4502000-0xf4502fff irq 19 at device 12.1 on pci0 ahc1: [ITHREAD] aic7896/97: Ultra2 Wide Channel B, SCSI Id=15, 32/253 SCBs Thanks in advance for your help, the archives of this list have been very helpful over the past 5 years. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
