However this was 2 node cluster and the output as we can see was showing 3 resources which was causing confusion. After checking MOS, as per Doc ID 2341248.1,

It is an expected behavior in 12.2,with Oracle Flex ASM, you can consolidate all the storage requirements into a single set of disk groups. All these disk groups are mounted by and managed by a small set of Oracle ASM instances running in a single cluster.  Irrespective of number of nodes in the cluster, only three ASM instances will be created

 

 

Solution:-

To disable it run the following.

-bash-5.2$ srvctl config asm ASM home: <CRS home> Password file: +DATA/orapwASM Backup of Password file: +DATA/orapwASM_backup ASM listener: LISTENER ASM instance count: 3 Cluster ASM listener: ASMNET1LSNR_ASM     -bash-5.2$ srvctl modify asm -count all
