A.

online.

B.
Use the operating system utilities to verify that your SCAN addresses are being properly
resolved.

C.
Start Oracle Enterprise Manager and check all monitored targets.

D.
Run the cluvfy comp nodecon �n all �verbose command to verify the entire Grid Infrastructure

Explanation:
Verifying the Grid Infrastructure Installation
Execute the crsctl command as shown in the slide to confirm that all cluster resources are up and
running.
root@racnode01 ~]# /u01/app/11.2.0/grid/bin/crsctl stat res -t
In addition, you should confirm that your DNS is properly forwarding address requests for your
application and SCAN VIPs to your GNS and that they are resolved properly. You can do this with
dig. Execute the dig command with DNS and VIP addresses as shown:
# dig @myDNS.example.com racnode01-cluster01.example.com
