I have a problem which probably has a very simple solution, but as I'm
inexperienced with configuring multiple SCSI drives, I'm currently at a
loss.
I have FreeBSD installed on my machine, and need to add a RAID to it.
Apparently, the problem is that the device id's are being assigned
incorrectly upon booting, because the machine boots just fine with
nothing plugged into the secondary SCSI controller (aha2940 I believe...
it sees the drives okay in any event, so I doubt that's the problem).
When I plug in the RAID, the BIOS sees the drives just fine, FreeBSD
recognizes the drives correctly, but I get a "panic: cannot mount root"
at the very end, which leads me to believe that it's assigning the
devices incorrectly, and thinks that the first SCSI drive in the RAID is
the root filesystem. I assume I'll have to hard-code in the devices, so
everything gets assigned in a consistent manner, but I'm not sure, and
am not clear on how to do this anyway (and don't want to waste my time
playing around with it if this isn't going to solve the problem). With
the RAID plugged in, sysinstall sees *only* the first four drives in the
RAID (on the _secondary_ controller card), but unplugged it sees the
three internal drives (primary card). Any ideas, or details on what
additional information I should provide to somebody assisting me with
this?
This is a dual pentium-pro 200mhz with 200M ram (waiting for 3.0 to
enable SMP support), with a 4-Gig internal boot, 2 9-Gig internal (ccd
works fine for them) drives, and 5 2-Gig drives (in a RAID cabinet)
hooked into the secondary controller card (everything SCSI). This
machine will be used as a secondary machine for our web site, probably
spitting out around 100,000 pages per day (if it keeps pace with it's
twin) -- which is why we're using FreeBSD rather than NT.
Thanks
