Oracle 12c: Rre-Create Scan Listeners

During our recent installation/configuration of pushing agents out for OEM Cloud 12c, my team somehow deleted or removed (2) of our Scan_Listeners.  Prior to our mishap with OEM Cloud, we had all (3) Scan_Listeners:

Scan_Listener01
Scan_Listener02
Scan_Listener03

Now we are only left with a single, Scan_Listener01. Does this seem appropriate to recreate:

[grid@mynode]$ srvctl add scan_listener -netnum 2 -listener testscan  -endpoints TCP:1528
 
[grid@mynode]$ srvctl config scan_listener -netnum 2 SCAN Listener TESTSCAN_SCAN1_NET2 exists. Port: TCP:1528 Registration invited nodes: Registration invited subnets:
 
[grid@mynode]$ srvctl start scan_listener -netnum 2
 
[grid@mynode]$ srvctl status scan_listener -netnum 2 SCAN Listener TESTSCAN_SCAN1_NET2 is enabled SCAN listener TESTSCAN_SCAN1_NET2 is running on node SalesSrv146

I believe these scan listeners are initially created during the Grid Infrastructure installation.

Hi,

During downtime:
#stop scan
srvctl stop scan_listener
srvctl stop scan
#update config by setting it back again
srvctl modify scan -n <put your scan address here>
srvctl modify scan_listener -u
#get  current config
srvctl config scan
srvctl config scan_listener
#if all seems fine
srvctl start scan
srvctl start scan_listener

Believe scan commands must be run by root.  At minimum the "scan update".
