Specify GNS in Grid Infrastructure installation
As a part of the configuration, you need to specify the Hub nodes and Leaf nodes. For example, Figure

shows
a seven-node Flex Cluster with three Hub nodes and four Leaf nodes.
Figure 4-4.
Specify the role of the Cluster nodes
As a part of Flex Cluster configuration, Oracle Flex ASM is implicitly enabled.
After the successful installation of the GI, you should be able to verify the cluster is in Flex Cluster.
crsctl get node role {config|status} [-node <nodename> | -all]
For example, to check the role of the current cluster node:
$ crsctl get cluster mode status
Cluster is running in "flex" mode
List all roles of all the nodes in a cluster by running this on any node:
$ crsctl get node role status -all
Node 'knewracn1' active role is 'hub'
Node 'knewracn2' active role is 'hub'
