Please desccribe your setup!

What is your storage?
How is it connected to your system?
Which driver do you use? (and whichc version?)
Do you use multipathing software?

etc.....

Sorry to be blunt, but without knowing what your system looks like the chance of finding the culprit in your setup is zero.
