Warning: you will need to re-install all software and restore user data
from backups after changing the partition layout.  Changing partitions
will cause all data on the drive to be lost.  Be sure you have the drive
backed up if it contains any user data.  Continue? y
After changing the partition, the other partitions will
be adjusted around it to fit the change.  The result will be
displayed and you will be asked whether it is OK, before the
change is committed to disk.  Only the standard partitions may
be changed with this function.  Type ? at prompts for a list
of possible choices

You can now add the s1 swap partitions to the /etc/fstab file like this:

/dev/dsk/dks12d3s1 swap swap pri=2 0 0

the machine will add the swap space on the next reboot, or you can add by hand:

# swap -a /dev/dsk/dks12d3s1
