Live Upgrade Issue

I tried a live upgrade for one my solaris 10u8 server which didnt go sucessfull and after that i now have following mounts in memory.

df: cannot statvfs /.alt.sol10u8_2/var: No such file or directory
df: cannot statvfs /.alt.sol10u8_2/var/run: No such file or directory
df: cannot statvfs /.alt.tmp.b-Zac.mnt/var/run: No such file or directory

Is there any way if i can remove these one from the system w/o rebooting it ?
