Thanks to the following for suggestions and possible explanations:

This is how it's done without a cd-device:
Write the disklabel using the a partition
# disklabel -wr -t ufs /dev/rrz6a rz26
# newfs /dev/rrz6a rz26
nfs mount the cd from node pollux
# mount -t nfs pollux:/cdrom /nfs_mnt
Mount the new root disk
# mount /dev/rz6a /mnt
Copy the contents of the cd to the new root disk
# vdump -0 -vf - /nfs_mnt | (cd /mnt; vrestore -x -f -)
path : /nfs_mnt
dev/fset : pollux:/cdrom
type : nfsv3
vdump: Date of last level 0 dump: the start of the epoch
vdump: Dumping directories
vrestore: Date of the vdump save-set: Mon Mar 17 13:46:29 1997
.....
vdump: Status at Mon Mar 17 14:55:54 1997
vdump: Dumped 488022722 of 488022722 bytes; 100.0% completed
vdump: Dumped 747 of 747 directories; 100.0% completed

# umount /mnt
Shutdown the system and reboot from the new root disk.
The trick was to use the a partition and not the c partition
of the new root disk.
