ACTUAL BEHAVIOR
---------------
While attempting to setup udev rules for ASM disks, the following "link" errors are seen. The same setup is working on other systems.
Command used to test setup:
udevadm control --reload-rules && udevadm trigger --action=add
"symlink '../../sdc' '/dev/oracleasm/disks/DATA.tmp-b8:32' failed: Operation not permitted"
UDEV rules file : /etc/udev/rules.d/99-oracle-asmdevices.rules
