check here...

yes I am root user.

It is not an NFS mount or a directory set in Automounter? /home is a typical example of this.

I bet you are in a sparse zone. If thats the case, then these filesystems are readonly in the zone:

  • /lib
  • /platform
  • /sbin
  • /usr

If you have to make changes to these directories then you have to do it in the global zone.

To verify that you are in a non-global zone, type

zonename

If it prints something different than "global", you are in a zone.
