Hi,

   Output for few CLI commands are quite straight forward, say just
reading a file content from that filer.  =20

But when those command support are extended in a cluster environment (to
get each node information), we need a daemon which can service that
request.

=20

We request for inputs/feedback if we can provide this support in
chassisd for the following commands.

=20

1.	"system version" reads the file "/version" (in that filer) to
get the EverON version. While this command is moved to a cluster level,
we need a daemon to service the same during cross-node request. Can this
system specific request be serviced in daemon chassisd? Also to note,
"system show version" is already being serviced in this daemon.=20
2.	New CLI command "system show users", reads the file
"/var/run/utmp" to get the logged in user details ("who" equivalent).
Can this login in specific request also be serviced in chassisd?=20

=20

Thanks & Regards,

Yuva.
