Objective:
1. Dual IBM 160MB/sec drives on one channel of aic7899 controller
2. DVD-RAM, ZIP, etc on other channel of aic7899
Bottom line:
failure
Operating System
FreeBSD 5.0-CURRENT
buildkernel slice 03 Oct 1200 GMT (no GEOM)
buildworld slice 27 Sep 1200 GMT (too many errors since then)
Hardware
Tyan 2642 SMP Thunder K7
2 X 1.2GHz Athlon
512M DDR266 memory
dual channel aic7899 SCSI controller
dual 3com 'xl' NIC
Matrox Millenium II with 8 MB
2 x 9G 10,000 RPM 160 MB/sec ~4ms access drives
Creative 5.2G DVDRAM
Iomega ZIP 100
modus operandi:
installed da0/1 on channel A of aic3899
channel A and B report in run-up (dmesg)
ahc0: <Adaptec aic7899 Ultra160 SCSI adapter> port 0x1400-0x14ff mem 0xf4002000-
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
ahc1: <Adaptec aic7899 Ultra160 SCSI adapter> port 0x1800-0x18ff mem 0xf4003000-
ahc1: bus_alloc_resource() failed to allocate IRQ
device_probe_and_attach: ahc1 attach returned 12
prior to 27 Sep, dmesg did not report ahc1; both were
reported as ahc0 and which ever channel was in use
reported the "SCSI Id=7, 32/253 SCBs". I don't know what
the controller reported on 31 Dec 01 except that it worked
correctly with 5.0-CURRENT at that time. I have another
machine I can bring on line as soon as I can get a KVM and
display card shipped out here to the boonies and I intend
to find out.
This message was printed when da0/1 were attached to
Channel A and the DVDRAM and ZIP were attached via a 68-50
adaptor to Channel B --if Channel B was recognzed, it
would also have printed "SCSI Id=7, 32/253 SCBs". If the
installation was reversed (da0/1 on Channel B), although
the loader would boot from da0, at the pass off to the
kernel it would try to load from da2 (ZIP) which, of
course, failed and panic'd.
installing da0/1 on Channel B, although recognized in the
BIOS display, and the loader, the loader would and bring
up the prompt:
mountroute>
All of these modes were done both with and without
hints. Hints had no effect on the results. I tried at
least 15 permutations of cabling and hints to the same
bottom line.
Net result:
installed da0/1 on Channel A of aic7899
installed cd0 (DVDRAM) and da2 (ZIP) on Tekram DC395U
see hints file following, although hints were not required.
it works, but it is a bit absurd, given that there is a
[supposedly] perfectly good Channel B lying around and the
Tekram DC395U/W is unsupported, therfore requiring me to patch
it back in every twelve hours at cvsup time.
patches and suggestions welcome --and reasonable ones will be
tested. After I shakedown the 04 Oct 1200Z kernel, I will
enable GEOS and shake it down. Then PHK has a patch for the
SCSI cd code which I will implement and shake --if I get that
far!
----- appendix -----
N.B. I have copies of way too many variations of loading and
their hints if you wish to peruse the permutations.
