The current setup is a two node standard cluster.
$ crsctl get cluster mode status Cluster is running in "standard" mode $ asmcmd ASMCMD> showclustermode ASM cluster : Flex mode disabledThere are few per-requisites to converting ASM to flex ASM, these include that OCR, SPFile and password file all stored in a disk group and this group have ASM compatibility (COMPATIBLE.ASM) set to 12.1 or higher. If this is not the case then make the necessary changes to move these files to disk group. As the current setup is a newly installed 12c cluster (as oppose to upgraded to 12c) these files all reside in disk group.
A point to note is that the diskgroup with above mentioned files has the size of 5114MB (below output has been modified by omitting some columns).

One of the key features of flex ASM is there's no one-one relationship between ASM instance and database instance. In a non flex ASM configuration failure of ASM instance would mean that database instance on that node will also fail. However with flex ASM in the event of an ASM instance failure the database instance is free to continue using a remaining ASM instance. This could be tested by stopping an ASM instance in one of the nodes
