Solution:

Check for the shared disk permission is under grid user and grid primary group

Eg:

Here the permission of the shared asm disks are under root

[root@testdb01 dev]# ls -ltr test_data test_fra test_ocr
brw-rw---- 1 root disk 253, 3 Dec  2 12:36 test_data
brw-rw---- 1 root disk 253, 5 Dec  2 12:36 test_fra
brw-rw---- 1 root disk 253, 6 Dec  2 12:36 test_ocr
[root@testdb01 dev]#

Change the owner to grid with oinstall and start the serevices

[root@testdb01 dev]# chown grid:oinstall test_data test_fra test_ocr
brw-rw---- 1 grid oinstall 253, 3 Dec  2 12:36 test_data
brw-rw---- 1 grid oinstall 253, 5 Dec  2 12:36 test_fra
brw-rw---- 1 grid oinstall 253, 6 Dec  2 12:36 test_ocr
[root@testdb01 dev]#
