PERC H700 RAID 5, 3 Drives, Reporting 1 failed and 1 predictive failure

Hi:

I have a PowerEdge T410 with a PERC H700, RAID 5 w/3 drives.  The controller reported a failed drive so I replaced it last week with a new/refurbished drive.  Now just 1 week later it's reporting a different drive failed and the replaced drive as predictive failure.  Seems suspicious, i.e. I'm doubting the controller card.  

I'm thinking to update the controller firmware first but not sure if I should replace the failed drive first, i.e. if updating firmware could cause array to fail.

Also, if I install OpenManage on a VM (host is ESXi 4.1), does OM see the controller?

Thank you!
