Package: libaio-0.3.105 (x86_64) - This is a prerequisite condition to test whether the package "libaio-0.3.105 (x86_64)" is available on the system.
Expected Value

Actual Value
 : missing
 Details:
 - 
PRVF-7532 : Package "libaio(x86_64)-0.3.105" is missing on node "ITL-BMRTEST1"  - Cause:  A required package is either not installed or, if the package is a kernel module, is not loaded on the specified node.  - Action:  Ensure that the required package is installed and available.

But when I do

rpm -qa|grep libaio-0.3.105
>libaio-0.3.105-2

Can any one tell me what I need to do?

Thanks
