Sometimes when you check Oracle Cluster Status Via “crs_stat -t” :

------------------------------------------------------------
ora.orcl.db    application    ONLINE    ONLINE    rac1
ora....11.inst application    ONLINE    ONLINE    rac1
ora....SM1.asm application    ONLINE    ONLINE    rac1
ora....DC.lsnr application    ONLINE    ONLINE    rac1
ora....idc.gsd application    ONLINE    ONLINE    rac1
ora....idc.ons application    ONLINE    ONLINE    rac1
ora....idc.vip application    ONLINE    ONLINE    rac1
ora....SM2.asm application    ONLINE    UNKNOWN   rac2
ora....C2.lsnr application    ONLINE    ONLINE    rac2

ora....dc2.ons application    ONLINE    ONLINE    rac2
ora....dc2.vip application    ONLINE    ONLINE    rac2

If You try to restart Oracle Cluster via

./crs_stop -all
./crs_start -all

It will not working so you have to do the following simple steps :

 First :

crs_stop -f Service_name
 
Example :
crs_stop -f ora.rac2.ASM2.asm

 Second :

crs_start -f services_name

Example :

crs_start -f ora.rac2.ASM2.asm

Thank you
