[root@node-01 install]#
Solution:
The ASM Lib configuration was done with oracle id,But the grid installation i am doing with grid user.
[root@node-02 11202stage]# /usr/sbin/oracleasm configure
ORACLEASM_ENABLED=true
ORACLEASM_UID=oracle
ORACLEASM_GID=dba
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER=""
ORACLEASM_SCANEXCLUDE=""
ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"
[root@node-02 11202stage]#
Update the configuration of ASMlib
/usr/sbin/oracleasm configure -u grid
[root@node-02 11202stage]# /usr/sbin/oracleasm configure
ORACLEASM_ENABLED=true
ORACLEASM_UID=grid
ORACLEASM_GID=asmadmin
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER=""
ORACLEASM_SCANEXCLUDE=""
ORACLEASM_USE_LOGICAL_BLOCK_SIZE="false"
[root@node-02 11202stage]#
For fresh installation delete the Disk group at asmlib.
/usr/sbin/oracleasm deletedisk OCR_VOTE01
/usr/sbin/oracleasm deletedisk ASM_DATA01
/usr/sbin/oracleasm deletedisk ASM_FRA01
And Recreate
/usr/sbin/oracleasm createdisk OCR_VOTE01 /dev/sde1
/usr/sbin/oracleasm createdisk ASM_DATA01 /dev/sdf1
/usr/sbin/oracleasm createdisk ASM_FRA01 /dev/sdg1
/usr/sbin/oracleasm listdisks
/usr/sbin/oracleasm scandisks
Now rerun the root.sh
