nslookup -> that depends on your DNS server
what do you see in?
$ srvctl config scan
Oracle suggests 3 IPs, so you can have 2 IPs for SCAN.
>Has anyone used the srvctl add scan_listener command
nope, I added IP SCAN and scan listener by using "crsctl"
Example:
# crsctl status res ora.LISTENER_SCAN1.lsnr -p
and then check attribute for using with SCAN2 Listener
and use
> crsctl add resource
