I logged in NetApp Management console today, and 4 new added filers are still not there.
So on only ONE of 4 new filers, I did:
options httpd.admin.enable on
options httpd.admin.ssl.enable on
Other items suggested by Roger Bergling have already done.
THEN LOGOUT Management Console, then log back in. Now, all 4 new filers show up under "Global".
I just don't know why it works, since I only did that two options commands on one filer, and why all the suddent all 4 filers come up.
