The general consensus was to use Veritas and encapsulation to get more than 
7 slices.  There are issues associated with single user-mode, booting from a 
CD that have to be addressed if you actually get the process to work.  In 
general that is the direction that I'll take, Veritas plus encapsulation.

Thanks to all.

Solaris 2.8 more than 8 slices HOW TO?

According to a SUN FE, he claims that the /usr/include/sys
files are not read at boot time.  Is the VTOC size (8 or 16) set as a
kernel parameter?  Does anyone have a procedure for creating more than 8 
slices on a Solaris disk?

The files in question /usr/include/sys:
vtoc.h
dklabel.h
isa_defs.h

isa_defs.h appears to define the number of slices:


*      _SUNOS_VTOC_8:
*              This is a VTOC form which is upwardly compatible with the
*              SunOS 4.x disk label and allows 8 partitions per disk.
*
*      _SUNOS_VTOC_16:
*              In this format the incore vtoc image matches the ondisk
*              version.  It allows 16 slices per disk, and is not
*              compatible with the SunOS 4.x disk label.

#define _SUNOS_VTOC_8 I changed that to #define _SUNOS_VTOC_16

Also, there is NDKMAP to 16?

What I am thinking is about the SUN FE saying that this files are not read 
at boot-time or used by the OS?!

After the changes, I rebooted... however, I was not able to create slices 
higher than 0-7?  What am I missing?  Has anyone done this before?
