Hammer & Screwdriver Assigning disks to grid user Solaris 11

hello....am trying to install Oracle 11gR2 RAC on Solaris 11 using Oracle Virtualbox, am stucked somewhere when trying to assign disk to grid user......I created five disks of 5GB each for ASM, I formatted them successfully but when trying to assign them to grid user, there is no changes as still appear that root is the owner

--Here are my disks
Code:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1t0d0 <ATA-VBOX
HARDDISK-1.0-40.00GB>
/pci@0,0/pci8086,2829@d/disk@0,0
1. c1t1d0 <ATA-VBOX HARDDISK-1.0 cyl
2558 alt 2 hd 128 sec 32>
/pci@0,0/pci8086,2829@d/disk@1,0
2. c1t2d0 <ATA-VBOX HARDDISK-1.0 cyl
2558 alt 2 hd 128 sec 32>
/pci@0,0/pci8086,2829@d/disk@2,0
3. c1t3d0 <ATA-VBOX HARDDISK-1.0 cyl
2558 alt 2 hd 128 sec 32>
/pci@0,0/pci8086,2829@d/disk@3,0

Specify disk (enter its number): 1     
selecting c1t1d0
[disk formatted]
No Solaris fdisk partition found
format> p

Type "y" to accept the default partition, otherwise type "n" to edit the partition table. y
format> p
partition> 0
Enter partition id tag[unassigned]:
Enter partition permission flags[wm]:
Enter new starting cyl[0]: 1
Enter partition size[0b, 0c, 1e, 0.00mb, 0.00gb]: 4.95g
partition> print
partition> label
Ready to label disk, continue? y
partition> quit
format> volname ASMDISK1
format> verify

I repeated same steps for the rest of the disks then as root user I changed the ownership to grid
Code:
chown grid:asmadmin /dev/rdsk/c1t1d0s0
chown grid:asmadmin /dev/rdsk/c1t2d0s0
chmod 660 /dev/rdsk/c1t1d0s0
chmod 660 /dev/rdsk/c1t2d0s0

---but when issued below command the disks still appear to be owned by root
Code:
ls -altr  /dev/rdsk/c1t1d0s0
# ls -altr  /dev/rdsk/c1t1d0s0
lrwxrwxrwx   1 root     root          51 Dec  7 21:40 /dev/rdsk/c1t1d0s0 -> ../../devices/pci@0,0/pci8086,2829@d/disk@1,0:a,raw

--grid user attributes
Code:
# id -a grid
gid=500(oinstall) groups=500(oinstall),501(asmadmin),502(asmdba),503(asmoper)

Might be due to the fact you're dealing with a symlink. Try -h (if available on your system); man chown:
Quote:
--dereference
affect the referent of each symbolic link (this is the default), rather than the symbolic link itself

-h, --no-dereference
affect symbolic links instead of any referenced file (useful only on systems that can change the ownership of a symlink)

Code:
thanks RudiC, using -h option saved my day, the disks are now assigned to grid user as expected.
chown -h grid:asmadmin /dev/rdsk/c1t1d0s0
