Before loading the OpenBSD kernel, at the bootloader type `boot -s`.
This boots the system in single user mode. Now you can manually mount
the root filesystem (`mount -u -w /`), and you can then fix your
/etc/fstab to exclude the broken disk.
Note that in single user mode, many userland tools are not available
if /usr is on a separate partition (which is a sane default). You'll
have to fix /etc/fstab with tools like cat and ed, or mount /usr.
Once things are fixed, unmount everything that you manually mounted,
and remount the root filesystem read-only again (`mount -u -r /`).
Then exit the single user shell, the system should continue booting
from there.
