I've a problem with a Compaq ProLiant 1600 which on which I've been installing FreeBSD (stable, as of about a week ago). I have 3 4.3Gb disks, and 2 18.2Gb disks connected to the internal SCSI (no SMART Array controller). This machine has had Linux installed for the best part of two years and has been fine, but times move on and now the hardware is supported in FreeBSD, and I want to Go There. The problem is that the kernel can see all the disks except one of the 18.2Gbs. They are all visible in the BIOS as the machine boots up, and "lsdev" in the BTX loader will display them all, but when the kernel boots, it doesn't see the second 18.2. Moving disks into different bays or removing some makes no difference: it flawlessly detects all installed installed disks except this particular one. As I mentioned, Linux can see it and use it OK. I guess it must be something to do with the firmware revision of this disk, and FreeBSD not liking it for some reason, but I'm at a loss as to how to proceed, so am seeking advice, or maybe some recognition of this problem from others. The problem disk has a slightly different code/revision from the one that is detected fine, and I think this must be the issue, but quite why FreeBSD doesn't like it when Linux is happy, I don't know. If it's helpful, the working 18.2 Gb disk is: AD018322C8 Rev A019 (Linux also reports scsi rev 02, and offset 15) (A Fujitsu, according to Compaq) The non-working one is: AD01832375 Rev ACJC (Linux also reports scsi rev 03, and offset 16) (A Quantum) I don't understand the significance of the difference in the scsi rev/offset numbers, not being a low-level hardware techie: forgive me. I've tried to upgrade the disks firmware, but according to the Options ROMPaq there are more recent ROM upgrades for the 18.3 disks available. The 4.3s were upgraded by it though. There's a similar-sounding problem at: http://www.FreeBSD.org/cgi/getmsg.cgi?fetch=487847+489731+/usr/local/www/db/text/2000/freebsd-questions/20001015.freebsd-questions which could boil down to the same issue: I couldn't find any follow-ups to that. Any advice welcome. Ta, Jethro. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
