Today i was trying to see why the ZFS Administration interface was not included on the web console’s application list. Well, i have a solaris 10 u4 (8/07) installation, and i think it should be enabled already. Maybe the fact that i did a “Secure by Default” installation has something to do with it… i don’t know what was the exact problem that answer the question “why“, but with a quick google search i could get half of the answer to “how to fix“. The other half is: the path has changed
The command i have used to register the ZFS administration interface was:

smreg add -a /usr/share/webconsole/webapps/zfs

And after that i need to restart the webconsole:

svcadm restart svc:/system/webconsole:console

Now, everything is fine…
