+
+Here the Name column shows the RELEASE NAME, In our case we want to try the
+scale operation on cassandra, thus the RELEASE NAME would be dev-cassandra.
+
+Now we need to obtain the chart name for cassandra. Use the below
+command to get the chart name::
+
+ > helm search cassandra
+
+Below is the example for the same::
+
+ > helm search cassandra
+ NAME CHART VERSION APP VERSION DESCRIPTION
+ local/cassandra 10.0.0 ONAP cassandra
+ local/portal-cassandra 10.0.0 Portal cassandra
+ local/aaf-cass 10.0.0 ONAP AAF cassandra
+ local/sdc-cs 10.0.0 ONAP Service Design and Creation Cassandra
+
+Here the Name column shows the chart name. As we want to try the scale
+operation for cassandra, thus the corresponding chart name is local/cassandra
+
+
+Now we have both the command's arguments, thus we can perform the
+scale operation for cassandra as follows::
+
+ > helm upgrade dev-cassandra local/cassandra --set replicaCount=3
+
+Using this command we can scale up or scale down the cassandra db instances.
