In your current configuration, you can't mirror all four drives. You could mirror /data2 and /data3 to c1t3 and c1t5 (this is assuming that you aren't using them at this time for anything).

If you wanted to mirror all drives, then you would have to free up one drive to allow 3 empty/unused drives. Since you haven't put the partition tables, it is hard to tell what space is being used by swap.

A possible solution is to move /export/home to c1t0 but even this would cause issues since you have both the OS partitions and /data on the same drive. Performance may be effected in attempting to have so much on c1t0.
There is also an issue with /data2 and /data3 - if they are using all the space on the drive, then you would have nothing left for a metadb (which doesn't require much space, maybe 1 cylinder but it would still cause a possible issue if you have to reformat /data2 and /data3)

Currently:
c1t0d0 - / /var /data /opt 116477898
c1t1d0 - /export/home 49580320
c1t2d0 - /data2 141065220
c1t3d0
c1t4d0 - /data3 141065220
c1t5d0

Possible solution ( Don't assume this will work - it doesn't take into account your swap partition and metadb slices or the effect of /data on c1t0)
c1t0d0 - / /var /data /opt /export/home 128885302
c1t1d0 - mirror c1t0
c1t2d0 - /data2 141065220
c1t3d0 - mirror c1t2
c1t4d0 - /data3 141065220
c1t5d0 - mirror c1t4

All in all, you really need to rethink what this needs and how to set it up. Having /data on the same drive as /, /var, /opt will possibly cause issues with the drive and how many writes will be going to that one drive (and then if it's mirrored, to the mirrored drive). Post the partition table of c1t0.

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.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
