ORA-01031: insufficient privileges On ASM – Grid Infrastructure 11gR2

Today like any other day started with customer call , Telling me There is problem on Grid infrastructure after restarting both node, They change heartbeat from cables to connected on switch after i told them to do this.

The Error in the logs like the  below :-
CRS-5011:Check of resource “+ASM” failed: details at “(:CLSN00006:)”

Node #2 was running without any problem , the issue was with node #1 and nothing changed recently.

The Error in Node #1 :-

crsctl start cluster

PRCR-1079 : Failed to start resource ora.asm
ORA-01031: insufficient privileges
CRS-5017: The resource action “ora.asm start” encountered the following error:
ORA-01031: insufficient privileges
. For details refer to “(:CLSN00107:)” in “/u01/app/grid/”.

as you see from the above error “ORA-01031: insufficient privileges” i was running this command as root.
After check node #1 the solution so simple :-

Under $GRID_HOME/network/admin
vi sqlnet.ora


which is wrong and to be changed to the following value :-


Reboot Node #1 and everything running successfully.

Thank you
