How early in the boot is this? Have you done 'vinum start' yet?
If that doesn't work, does 'vinum read vinumdrive0 vinumdrive1' work?
Other simple things to check: if you've booted single-user, be sure to remount
the root filesystem read-write by doing
mount -o rw /
before vinum can create devices. You can force vinum to recreate the device
nodes by doing
If all that doesn't work I'm also at a loss as to what it can be.
