You need to put a VTOC on the drive by using the fmthard(1M) command.
This command is defined in the System Administration Reference Manual.
Also, take a look at the prtvtoc(1M) command to see what the vtoc table
should look like.  The task before you is to enter a vtoc as
shown in the example with the prtvtoc(1M) command into a file, then
execute the the fmthard(1M) command as given here:

fmthard -c2 -m -s file_with_vtoc -n volume_name /dev/rdsk/c?d?s6

I am assuming with the -c2 option that this is the second disk.  If this
second disk is daisy chained off of the root drive, then the device to
use is most likely /dev/rdsk/c1d1s6, if this is a disk off of a XDC card,
then the device might be /dev/rdsk/c2d0s6 or /dev/rdsk/c2d1s6.  Determining
the correct device name is left as an exercise for the student.
