Then look back the Cluster Resource Issue

at first ,we try to start res db manually using srvctl .

checked 
the dependency for the database resource

 

Solution:

 

Since ASM diskgroup FRADG has been physically dropped. We should to remove FRADG resource from CRS start/stop dependency for database resource ora.db.db.

Cleanup Diskgroup Cluster resources

How 
to drop asm groups in RAC? sqlplus in asm, asmca, EM. either ones will 
work.

 

A FAQ in OTN

Question then is, is there one command that I can run which will do both? drop the diskgroup AND as a RAC resource.
If you use SQLPLUS to drop Diskgroup you must to use "srvctl remove diskgroup -g" to remove diskgroup from OCR.

If you use ASMCA one step remove both.

No, there is no one command to do it.... but is easy with 4 command.
e.g:
oracle@node1 > sqlplus / as sysasm
SQL> sqlplus / as sysasm

SQL> ! srvctl status diskgroup -g DATA
Disk Group DATA is running on node1,node2,node3

SQL> ! srvctl stop diskgroup -g DATA -n node2,node3

SQL> DROP DISKGROUP DATA;

SQL > ! srvctl remove diskgroup -g DATA

On release 11.2.0.2, after drop a diskgroups ASM is not releasing file descriptors on the raw devices.
Document 4693355.8 states that this problem (Bug:4693355 & Bug:7225720) is fixed on release 11.2.0.1.0, but the problem persists on release 11.2.0.2.0. Even if DROP DISKGROUP or DISMOUNT DISK GROUP scenarios.

Note that the forced disk group dismount will cause all datafiles in that database to go offline, which means they will need recovery (and restore if I drop disk group PLAY)
