It's a Cluster?
From 11.2 and above ASM feature is not part of Oracle RDBMS installation. ASM feature is part of Grid Infrastructure Installation.
Oracle Restart for standalone env - option Grid Infrastructure for a Standalone.
Oracle Clusterware for a Clustered env - option Grid Infrastructure for a Cluster.
If you plan to use Oracle Restart or Oracle Automatic Storage Management (Oracle ASM), then you must install Oracle Grid Infrastructure before you install and create the database. Oracle Grid Infrastructure for a standalone server is the software that includes Oracle Restart and Oracle ASM. Oracle combines the two infrastructure products into a single set of binaries that is installed as the Oracle Grid Infrastructure home.
From your OP I think you are using ASM on Standalone host. So, you should be using Grid Infrastructure for Standalone Server ( Oracle Restart).
No more "localconfig"
From 11gR2, you won’t see localconfig file anymore in Oracle Home of Grid Installation.Oracle 11gR2 introduced OHASD (Oracle High Availability Service Daemon) which gets created,at the end of the installation by running root.sh.This OHASD has ora.cssd service which is the CSS service used for synchronization between ASM instance and DB.
At end of your installation OLR is backed up on " $GRID_HOME/cdata/localhost/" if you lost your OLR you should recover then.
