Itisha,   The latest version of MDSM is included in the MD32xx resource ISO, found here, which includes support for the controller.    Let me know if this helps.    
Can anyone tell me which version of MDSM is compatible with RAID controller firmware: 08.20.20.60 for MD32xx ? The MDSM version 10.84.G6.25 is not compatible; which MDSM version should i install?    
MDSM compatibility version for MD32xx
