Read about what new firmware fix from the olders. A lot of hw/sw problem in raid are just for an outdated firmware (is common for example, in the IBM 8k raid to have raid crashes with some fw versions... the common procedure is: if you have NO problems, never update any fw (unless some driver or something requires). If you have problem, update to last level and test again.
Next time please... take note (or a picture with your phone) of the exact error... that would help us to help you in a better way! :P
