Emergency boot floppy set and mirrored root disks
If you have a mirrored root configuration, there are
several important considerations when creating and using an
emergency boot floppy set:
If you create a mirrored root filesystem, create a new emergency boot
floppy set immediately. If possible, create a system-specific Boot
Disk rather than a generic one.
If you must create a generic Boot Disk (when the system-specific kernel
does not fit on a floppy disk), then only the original piece of the
mirror will open when the system is booted. You cannot use this Boot
Disk on another system with a mirrored root.
When using the emergency boot floppy set to boot the system, use this
bootstring instead of just pressing <Enter> at the Boot prompt:
defbootstr fd(60)unix.Z root=vdisk(1) swap=none dump=none
If root is not directed to
vdisk(1), then the two halves of
the mirror will become out-of-date, which could corrupt the filesystem
when the machine is next booted from the hard disk.
