Sorry there isn’t much in the way of comments or coloring.  It was just copied from the terminal window.  The procedure below does create the ZFS filesystem, clone it, move it, then deletes the old ZFS information.

The procedure uses disks mapped from and EMC array.  The reason it was needed is that a new EMC was introduced so the data needed to be copied from the old EMC to the new EMC disks, and the old EMC disks needed to be disconnected.

The procedure will walk through creating a volume, adding data to it, cloning it, swapping volumes, and deleting the original.

done

Once you know the PID’s of the processes you can determine all of the atributes of the applications using pargs, instead of ps. In Solaris 10 the /usr/ucb/ps is the same AT&T version as /bin/ps, so the output is not very handy.

sudo pargs PID

The output for both will look like the following
