I searched around any saw nothing on this issue. I have an ML350 G4p box with 641 array controller and a full cage of 36gig drives on raid 5. During warm boots sometimes one or more of the disks will go offline. I have to power the box off and cold boot to get the array online again. I have replaced the controller card, the cage backplane, the cable and the drives and still get the same issue. I suspect some system board firmware issue at this point. Any thoughts or advice would be greatly appreciated.
