Hi,
I have two scsi controllers, a built-in 7890 and a 2940-U2W. When I
installed, bios drive "0" and da0 were at ID 0 of the 7890 controller, so
the boot process and the root filesystem were both on the potentially
buggy 7890.
To see if I could fix the problem by booting from the 2940-U2W, I swapped
the drives from one controller to the other and told the BIOS that the
7890 should *not* be the boot device. ahc0 is the 7890 and ahc1 is the
2940 card.
So it does now boot from that drive, but when it goes to mount root, it
wants to mount the first device on ahc0, which is another drive.
What determines the device mappings here? Can I fix this or must I
reinstall? Why does the built-in controller always get ahc0 instead of
ahc1?
Help.
Charles
