Some general ideas.

Well firstly before you cluster anything make sure your application can run on it's own without any problems ie make sure it's not buggy or crashes often, if it does crashes or problematic never ever cluster it, resolve all the problems first before clustering.

before clustering test out the sequence manually

ifconfig ce0:1 plumb
ifconfig ce0:1 xxx.xxx.xxx.xxx netmask 255.255.255.0 <<<--- usually the clusterservice group IP is also the IP that oracle listener uses

vxdg import <diskgroup>
vxvol -g <diskgroup> startall
mount /dev/vx/dsk/cXtXdXsX /oracle
mount /dev/vx/dsk/cXtXdXsX /oracle/u01
mount /dev/vx/dsk/cXtXdXsX /oracle/u02
mount /dev/vx/dsk/cXtXdXsX /oracle/u03
<oracle database starts with dbstart>
<listener starts lsnrctl start>

stop the application and umount in reverse
<listener stop lsnrctl stop>
<dbshut>
umount /dev/vx/dsk/cXtXdXsX /oracle/u03
umount /dev/vx/dsk/cXtXdXsX /oracle/u02
umount /dev/vx/dsk/cXtXdXsX /oracle/u01
umount /dev/vx/dsk/cXtXdXsX /oracle
vxvol -g <diskgroup> stopall
vxdg deport <diskgroup>
ifconfig ce0:1 down

Then on the other host try to bring up manually also using the sequence, make sure everything working without problem before you cluster anything.

I have very limited knowledge, some years back I migrated 4 node cluster into 2 node cluster merging a total of 38 oracle instances, how I did it was by a lot of pain and much trial and error and many change window (so painful) and I did it mostly by vi and editing the main.cf file, you can use vcs command line or easier use the gui. if you want to use command line because you dun have a console then better start checking up support.veritas.com, if you have a lot of instances to add then I feel it is easier to spend some time studying the main.cf and how you can go about modifying it to suite your needs.

then hacf -verify to check your main.cf script ( as long as the cf file check out without errors after modification it's fine)

Because everytime vcs starts it will read main.cf and automatically convert into main.cmd which contains vcs commands.

but if you still interested in command line, then here are some ideas.

best of luck

mmount

mmount(1)						      General Commands Manual							 mmount(1)

Name
       mmount - mount an MSDOS disk

Note of warning
       This  manpage  has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete.  See the
       end of this man page for details.

Description
       The mmount command is used to mount an MS-DOS disk. It is only available on Linux, as it is only useful if the OS kernel allows to  config-
       ure the disk geometry. Its syntax is:

       mmount msdosdrive [mountargs]

       Mmount  reads  the  boot  sector of an MS-DOS disk, configures the drive geometry, and finally mounts it passing mountargs to mount.  If no
       mount arguments are specified, the name of the device is used. If the disk is write protected, it is automatically mounted read only.

       Mtools' texinfo doc

Viewing the texi doc
       This manpage has been automatically generated from mtools's texinfo documentation. However, this process is only  approximative,  and  some
       items, such as crossreferences, footnotes and indices are lost in this translation process.  Indeed, these items have no appropriate repre-
       sentation in the manpage format.  Moreover, not all information has been translated into the manpage version.  Thus I strongly  advise  you
       to use the original texinfo doc.  See the end of this manpage for instructions how to view the texinfo doc.

       *      To generate a printable copy from the texinfo doc, run the following commands:

		     ./configure; make dvi; dvips mtools.dvi

       *      To generate a html copy,	run:

		     ./configure; make html

       A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html'

       *      To generate an info copy (browsable using emacs' info mode), run:

		     ./configure; make info

       The  texinfo  doc looks most pretty when printed or as html.  Indeed, in the info version certain examples are difficult to read due to the
       quoting conventions used in info.
