I have a Dell 29xx running windows server 2008.  One of the drives on the RAID 5 has failed.  Has a blinking Orange and is indicated as RAID 5 'Degraded' and the drive status 'Failed' in openManage.
What is proper way of replacing the failed drive I have Dell OpenManage Version 7.4.0
Thanks,
Joe

Replace it "hot" (while the server is running). Pull the drive, wait 30 seconds, put in replacement. If the drive does not start rebuilding automatically, assign it as a hot-spare (on either the Physical Disks or Virtual Disks page). If the drive is showing as "foreign", you need to first CLEAR the foreign configuration (OMSA, Storage, PERC, Information/Configuration, Foreign/Clear from dropdown menu of Available Tasks).

On the App under Virtual Disks.  I have an option to "Replace Member Disk" .  Should I select that 1st?

NO, do not do anything under the VD app.  Just pull out the old one put in the new one with system running.   Note - It is always best practice to backup anything that is vital before a rebuild.  Rebuilds touch 100% of the blocks on the drive.  It is also quite stressful. If you don't have a current backup, you don't want to risk losing a 2nd drive.

Just ONE unreadable block on the surviving disks means you will likely have some data loss.

(You won't get any foreign disk messages if this is a virgin drive that hasn't been yanked from a system that was already using a PERC controller).

No, you can just pull the disk if it is already offline/failed.
