/sbin/zonename file giving me problems

I'm trying to install the recommended patch cluster on a x86 Solaris 10 box.
I get this error:

ERROR: /sbin/zonename cannot be found. install_cluster for 10_x86 patch cluster not applied. Exiting.

I tried touching the file and it gave a different error of: expected argument..

anyone have this happen?

/sbin/zonename sounds like a command binary --- touching the file will not make it work ... see if you could copy it from somewhere ... try the install disk or another Solaris 10 x86 box ... good luck!
