Hi,
I am experimenting with Oracle 12c ASM on RHEL 7.1 GA. I am able to create a DG and mount it. But when I query v$asm_diskgroup, it returns no rows. Here is the necessary screenshots:
From alert.log:

When I login to the ASM instance:
-bash-4.2$ !sql
sqlplus "/ as sysasm"

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Automatic Storage Management option
SQL> select name,state from v$asm_diskgroup;
no rows selected
My environment variables for the user:
GRID_HOME=/oracle/grid
ORACLE_HOME=/oracle/grid
Please help! I suspect that this is preventing the oracle DB installation from recognizing the ASM DG during installation.
