Have a PowerEdge R510 with a PERC H700 / RAID 5. Logs showed drive 3 failed but spun up. We replaced it (hot swap) with a new one (from Dell). Server administrator still shows drive 3 as failed but spun up, the logs show nothing except blinking / unblinking the failed drive before it was removed (logs don't show the removal / replacement or a rebuild starting). Is there something we're missing in the H700? Thanks.
