Changes to LVM are written to the ODM and onto the disks. They are permanent and can't be resolved by a reboot. After a reboot your box will not come up again, since you destroyed it's rootvg. It is currently only working, because the programs are in memory.
If there is a mirror set up between hdisk0 and 1, the copy will most probably be destroyed as well.
I guess you have to reinstall or restore a backup of your rootvg.
You simply have to take care with what you do.
