I just got thru building a disaster disk for my system, after reading 
some articles from others on the net who have done the same 8^).
The place for you to start is make a copy of your ESIX boot/install
diskette.  Put the diskette in the drive and mount it like so:
mount /dev/dsk/f0 /mnt.  You'll get a message warning you about
install mounted on /mnt, this is because the disk file system name
doesn't match the name of the dir you're mounting it on (see labelit(1M) ).
Now you can just cd into /mnt and start exploring.  The biggest problem
I ran across was disk space, my floppies only hold 1.2MB and I was hard
pressed to fit everything I wanted on the disk.  You may want to strip
all the utilities on the disk and replace the unix on the disk with a
minimally configured kernel you build via kconfig.  It can have *just*
those drivers required, mine has the Wangtek driver in it so I can 
boot from floppy, much around with the drive with the disk* utilities,
do my mkfs's and restore from tape. Remember to mknod the tape devices
on the disaster floppy after copying your minimally configured unix
to it.
