ZFS root Issue

I jumpstarted a solaris sun4u box from WANboot and it completed but while coming up it gives following error and panics

I booted the system into single user mode and mounted rpool and found that the bootfs ID no. is 47 on this no. which needs to be higher ..

So my question is .. Is there any way to do this ? The flash archive being used is from solaris10 u9 system running on M5K domain.
