Which two types of IP address details are administered using the srvctl command for Oracle Clusterware 12c?
A.
the Grid Naming Service (GNS) VIP
B.
public IP addresses
C.
High Available VIP (HAIP) addresses
D.
Single Client Access Name (SCAN) VIPs
E.
Storage Network IP addresses
Explanation:
A: To convert a cluster that is not running GNS to a GNS server cluster, run the following command as root, providing a valid IP address and a domain:
# srvctl add gns -vip IP_address -domain domain
D: Example:
1. Modify the VIP using a VIP name that resolves to IPv6 by running the following command as root:
# srvctl modify vip -node node_name -address vip_name -netnum network_number
Do this once for each node.
2. 2. Modify the SCAN using a SCAN name that resolves to IPv6 by running the following command:
$ srvctl modify scan -scanname scan_name
Incorrect Answers:
C: The oifcfg command is used configure HAIP addresses. For example:
oifcfg setif -global eth3/172.16.2.0:cluster_interconnect

A,D CORRECT
To convert from a standard cluster to a Flex Cluster, an administrator should first ensure that GNS is configured with a fixed VIP. If GNS is not configured with a fixed VIP, the remainder of the procedure will fail.
srvctl add gns -i -d

The srvctl modify scan command modifies the SCAN
VIP configuration to match that of another SCAN VIP:
# srvctl modify scan –scanname cluster01-scan
I think so!
“B” – public is used for the server/node and cannot be normally altered
“C” – HAIP is for INTERCONNECT and they can not be normally altered too.
“E” – Storage is administered normally by S.O.
Normally, VIP are virtual and made to be moved and realocated, so GNS VIP’s and SCAN VIP’s…
