Your device file isn't under a VG directory. It should be:

pvcreate /dev/rdsk/c2t3d4

Hello Eberno,
as already mentioned you are using wrong device file. you should create disks using
pvcreate /dev/rdsk/CxtXdX and not /dev/vgXX/cXtXdX.

your second problem, Do you want to mirror the disk? If yes, use the following steps.

1. pvcreate /dev/rdsk/CxtXdX (with your new disk)
2. vgextend /dev/vgxx /dev/dsk/CxtXdX (With your new disk)
3. use lvextend command to copy the logical volumes
#lvextend -m 1 /dev/vgxx/LVNAME /dev/dsk/CxtXdX.

If you are note sure with the steps, use SAM.
