SCAN name: cluster1-scan, Network: 1/12.168.1.0/255.255.255.0/eth0
SCAN VIP name: scan1, IP: /12.168.1.2/12.168.1.2
SCAN VIP name: scan2, IP: /12.168.1.3/12.168.1.3
SCAN VIP name: scan3, IP: /11.168.1.1/11.168.1.1

edit konfigurasi scan di DNS misal dalam grid.zone.nl( sesuaikan dengan settinga DNS masing 2)
cluster1-scan A 11.168.1.1
cluster1-scan A 12.168.1.2
cluster1-scan A 12.168.1.3

ubah menjadi :
cluster1-scan A 12.168.1.1
cluster1-scan A 12.168.1.2
cluster1-scan A 12.168.1.3
