Hello Vimal,

1) Upgrade the Firmware (specially the Controller)

I would recommend using the Firmware Maintenance CD 7.9
http://h18023.www1.hp.com/support/files/server/us/download/27783.html?jumpid=reg_R1002_USEN

This will make sure all the Firmware are updated, including the ones for the HDD;

Regards,
James.
