smartd is using a deprecated SCSI ioctl, please convert it to SG_IO

Hi All,
I have installed GNU Red Hat Linux on my server. The installation is successful except that it gives out a display as following:

program smartd is using a deprecated SCSI ioctl, please convert it to SG_IO

Please let me know if anyone has come across such an error and know the solution.

Thanks!

I used Google with "redhat smartd" and found in about 20 seconds:

linux.redhat: Re: My "smartd failed to start"?? what does that mean?

Also someone mentioned to simply disable it, if you don't use it.
