SCAN Listener configuration for monitoring
Following are scan configuration:
SCAN Name : akrfa.corp.adobe.com
SCAN VIP name: scan1, IP:/akrfa/10.5.106.86 LISTENER_SCAN1 akrfa-scan2.corp.adobe.com 1789
SCAN VIP name: scan2, IP:/akrfa/10.5.106.87 LISTENER_SCAN2 akrfa-scan3.corp.adobe.com 1789
SCAN VIP name: scan3, IP:/akrfa/10.5.106.85 LISTENER_SCAN3 akrfa-scan1.corp.adobe.com 1789
Now, in grid control all SCAN listeners (LISTENER_SCAN1, LISTENER_SCAN2 and LISTENER_SCAN3) are pointing to akrfa.corp.adobe.com and port 1789.
As per my understanding, LISTENER_SCAN1 should point to akrfa-scan2.corp.adobe.com or 10.5.106.86, LISTENER_SCAN2 should point to akrfa-scan3.corp.adobe.com or 10.5.106.87 and LISTENER_SCAN3 should point to akrfa-scan3.corp.adobe.com or 10.5.106.85 in Grid Control. This will help to monitor which scan listener is down and up.
