SUMMARY: liveupgrade to upgrade form solaris 9 to 10

thanks to all people who responded(bill fitts, tim evans, ade fewings, 
useel lebar, ying xu, charlie giannetto, tom crummey), sorry for late 
summary, we stopped our servers during 2 days...

everyone said: "do what it say!"

but pay attention to what you do, because, to upgrade sol9 to 10, you 
have to have sufficiant space in /, and that's not the case for me!
on solaris 9, / sizes 4.8Gb, and this machine is a v210 with 2 hard 
disks. So want to use second disk to upgrade, and did a fmthard and 
prtvtoc to have the same disk, and liveupgrade failed because sol10 
needs more space than 4.8Gb!
so i have to retry
