How to use kudzu to find new disks in RHEL 5

[liuyl_it]

HP BL460c with 8Gbps VC-FC、 HP EVA8000 and RHEL 5.4

Can I use kudzu to find new disks/LUNs in RHEL 5,  instead of using echo "---" > /sys/class/scsi_host/hostX/scan ?
Notes: although I can normally run the kudzu successfully,  but in fact no any new disks can be found！

Thanks！ And I review the above link for the kudzu bug fix. 
But it just contains the two bugs::  sound card and net MAC！
So I think this should have nothing to do with adding new disks！
