How to mount two or more devices in the same mount point?

1. Creating a mount point
bash-3.00# mkdir /mnt/new

2. Mounting the device in the created mount point
bash-3.00# mount /dev/dsk/c1d0s4 /mnt/new/

3. Verifying the device mounted & its mount point
bash-3.00# df -hFilesystem size used avail capacity Mounted on
/dev/dsk/c1d0s0 9.9G 3.2G 6.5G 34% /
/devices 0K 0K 0K 0% /devices
ctfs 0K 0K 0K 0% /system/contract
proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
swap 22G 736K 22G 1% /etc/svc/volatile
objfs 0K 0K 0K 0% /system/object
/usr/lib/libc/libc_hwcap2.so.1
9.9G 3.2G 6.5G 34% /lib/libc.so.1
fd 0K 0K 0K 0% /dev/fd
swap 22G 48K 22G 1% /tmp
swap 22G 40K 22G 1% /var/run
/dev/dsk/c1d0s4 2.0G 2.0M 1.9G 1% /mnt/new

4. Now if we try to mount another device in the same mount point, we face the following error message:
bash-3.00# mount /dev/dsk/c1d0s5 /mnt/new/
mount: /dev/dsk/c1d0s5 is already mounted or /mnt/new is busy

5. So, to mount another device in the same mount point,
bash-3.00# mount -O /dev/dsk/c1d0s5 /mnt/new/

6. Verifying the device mounted & its mount point
bash-3.00# df -hFilesystem size used avail capacity Mounted on
/dev/dsk/c1d0s0 9.9G 3.2G 6.5G 34% /
/devices 0K 0K 0K 0% /devices
ctfs 0K 0K 0K 0% /system/contract
proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
swap 22G 736K 22G 1% /etc/svc/volatile
objfs 0K 0K 0K 0% /system/object
/usr/lib/libc/libc_hwcap2.so.1
9.9G 3.2G 6.5G 34% /lib/libc.so.1
fd 0K 0K 0K 0% /dev/fd
swap 22G 48K 22G 1% /tmp
swap 22G 40K 22G 1% /var/run
/dev/dsk/c1d0s4 2.0G 2.0M 1.9G 1% /mnt/new
/dev/dsk/c1d0s5 2.0G 2.0M 1.9G 1% /mnt/new
