Assuming a newdisk c0t1d0. Create the new 6GB filesystem and name it /var2 on c0t1d0s5

shutdown server
sync;sync;sync;init 0
boot cdrom -s

(cdrom single usermode )
# mount /dev/dsk/c0t0d0s0 /mnt <---- mount your OS disk
# mount /dev/dsk/c0t1d0s5 /a <---- mount /var2

cd /mnt/var
tar cvfp - * | (cd /a;tar xvfp -)

TERM=vt100;export TERM
EDITOR=vi;export EDITOR

cd /mnt
mv var var1
cd /mnt/etc
cp -p vfstab vfstab.`date +%d%m%y`

vi vfstab

'#' off the entry for var if any
add the entry (make sure there are 7 columns)
/dev/dsk/c0t1d0s5 /dev/rdsk/c0t1d0s5 /var ufs 1 no logging

save+quit vi

umount /mnt
umount /a
fsck /dev/dsk/c0t0d0s0
fsck /dev/dsk/c0t1d0s5
stop-a
boot
if server comes up with no problem, that's fine, if any problem, just boot cdrom and revert everything back(mv var1 to var) + cp vfstab.`date +%d%m%y` vfstab

Ater that create your metadevices and mirror for the new /var (from here on I assume you shud know what to do)

If you are new to Sun my advice is don't experiment or do any personal R&D learning/testing on your production server.

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris	invokes  the  Solaris  Install	program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

	   Minimum physical memory for all installation types

       128 MB

	   Minimum physical memory required for windowing system

       384 MB

	   Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

	   Minimum physical memory for all installation types

       256 MB

	   Minimum physical memory required for windowing system

       512 MB

	   Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris	exists	only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.
