I have dell poweredge R520 with four drives 600gb each in RAID 5. One of the drive is blinking green and amber this means predictive failure. I have VMware 6.0 running on it with several VMs. To change the drive do I have to just take it out and insert the new drive with the server up and running or I have to shutdown the server and then insert the new drive?

Don't shut down a server to replace a hot-swappable drive. Swap it "hot". If it doesn't start rebuilding automatically, you will need to assign it as a hot-spare to start the rebuild.

HOWEVER, with it showing predicted failure, you need to force the drive (or prepare to remove) FIRST. If you don't have the OMSA VIB installed, then you will need to do this from the CTRL-R PERC configuration utility during POST, THEN replace the drive.

You don't need to shut down the server.  It's ok to replace the drive hot (powered up).  BUT, I would first make sure you have a good and tested backup.

When a drive rebuilds, it can put a strain on the other drives and possibly cause a second failure while the rebuild is going on. You do not want this to happen.

So, have a good backup, and replace your drive and let the build go.

scott - you can't do that on a dell server when only a predictive failure
it has to be manually put in a failed state first
hp servers you can do that though

Thanks, yes, it should have read: "you need to force the drive [offline] first"
