Make sure you reboot after adding that to /etc/system for making a safe clone I know there must be other ways to do it, but you could make a new zpool and do a zfs send/receive from old zvols to new ones.

Under Solaris 10 that I'm using now to recover this rpool I have rpool named as mypool01 it should not collide with a affected rpool that I want to recover and import or? So, "zpool import rpool rpool2" should only rename and import the pool with a new name? I'm wondering if I need to use -f to force it that I do not lose or damage something if "zpool import -f rpool rpool2" hangs again. Anyway, I will try this that you've suggested with settings in the /etc/system and to mount using zpool import -f -R /mnt rpool Do you know is there anyway to make the safe clone of affected disk?
