You will need to mount each file system before using the new partitions. As super user mount the UFS file system by using the mount command. (A mount point is a directory to which the mounted file system is attached.)
# mount [-o mount-options] /dev/dsk/device-name mount-point
For example, the following command mounts /dev/dsk/c0t3d0s7 on the
# mount /dev/dsk/c0t3d0s7 /files1
