Answer:
i only received 2 answers so far, they both are great !!
Glenn help me to solve my first problem:
mount: /dev/md/dsk/d10 write-protected
James answered my second question:
metattach: shadow: d11: can't attach labeled submirror to an unlabeled mirror
Even I did not try, but I believe that he is right, since i am trying use
the partition c0t4d0s0 as mirrow which has start address 0.
See the attached e-mail for both answers.
Thanks for the responses.

In this case d10 is the sub-mirror and d1 is the mirror
metadevice, so in /etc/vfstab you should be mounting
/dev/md/dsk/d1. Note that it doesn't have to be mounted to
attach the second sub-mirror. Your syntax for metattach is
correct though.
The output for metastat on these devices would be useful for diagnosing.

I don't know about the write protect problem,
But on the metattach error about submirrors,
The problem is that one partition includes the boot block, and the
other partition doesn't. DiskSuite doesn't like this. One way around this
is to define all your disk partitions starting at cyl 1 instead of cyl 0
(Except for your root and mirrored-root partitions of course).
Hope that helps you.
