Resize root volume with Solaris Volume Manager

I've got myself in a predicament. I'm tyring to resize the / partition
on a 220R with Solaris 9 using SVM. I was able to successfully resize
the submirrors d10 and d20 from 4gb to 20gb. But as you can see below:

bash-2.05$ metastat d0
d0: Mirror
    Submirror 0: d10
      State: Okay
    Submirror 1: d20
      State: Okay
    Pass: 1
    Read option: roundrobin (default)
    Write option: parallel (default)
===> Size: 8389656 blocks (4.0 GB)

d10: Submirror of d0
    State: Okay
    Size: 43889688 blocks (20 GB)
    Stripe 0:
        Device Start Block Dbase State Reloc Hot Spare
        c0t0d0s0 0 No Okay Yes

d20: Submirror of d0
    State: Okay
    Size: 43889688 blocks (20 GB)
    Stripe 0:
        Device Start Block Dbase State Reloc Hot Spare
        c0t1d0s0 0 No Okay Yes

Device Relocation Information:
Device Reloc Device ID
c0t0d0 Yes id1,sd@SSEAGATE_ST336704LSUN36G_3CD2297600007147HCBZ
c0t1d0 Yes id1,sd@SSEAGATE_ST336704LSUN36G_3CD224FS00007147K1KH

my mirror volume d0 is still showing a size of 4gb. Trying run growfs
-M / /dev/md/rdsk/d0 ends up hanging. I'm guessing because the volume
isn't any bigger it really can't create a larger filesystem.

Any suggestions on how to grow d0 so that I can grow the filesystem?

Much thanks.

Here's my df -hk just in case:

bash-2.05$ df -hk
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d0 3.9G 1.5G 2.4G 40% /
/proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
fd 0K 0K 0K 0% /dev/fd
/dev/md/dsk/d5 3.9G 179M 3.7G 5% /var
swap 5.6G 24K 5.6G 1% /var/run
swap 512M 0K 512M 0% /tmp
/dev/md/dsk/d6 3.9G 27M 3.9G 1% /opt
