Btw, is your 2 disks of the same size? Did you get any errors when you did prtvtoc? Why aren't the disks of the same type? Just noticed that..
oh.. The two disks have the same size. below is the output after did the prtvtoc. =)

Code:
root@leo # prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
fmthard:  New volume table of contents now in place.
root@leo # metadb -a -f -c2 /dev/dsk/c1t0d0s4 /dev/dsk/c1t1d0s4
root@leo # metadb
        flags           first blk       block count
     a        u         16              8192            /dev/dsk/c1t0d0s4
     a        u         8208            8192            /dev/dsk/c1t0d0s4
     a        u         16              8192            /dev/dsk/c1t1d0s4

As per Sun SVM process, there is no need to installbootblk
BigAdmin Submitted Tech Tip: Boot Disk Mirroring Using Solaris Volume Manager Software

But technically speaking, if we want to boot from 2nd disk which is mirrored, we have to install the bootblk on the 2nd HDD.

But my question is that whether Syncing process copy the bootbkl from 1st HDD ==> 2nd HDD ???

Vicky

Vicky,I think you are right....
No need to install bootblk .
During sync itself bootblks are copied...

Incorrect. If you want to be able to boot from the second disk the installboot is required.

No it is not copied. Installboot is required.
