Re: PowerEdge r710 rebooting - storage error
Is the drive showing predicted failure in OMSA?
Never shutdown to introduce a hot-swappable drive. In OMSA, force the drive offline (prepare to remove, etc.), then pull the drive, wait at least 60 seconds, then put the new drive in. It will probably rebuild automatically, but if it doesn't, you will need to assign the new disk as a hot-spare to start the rebuild.
Problem is that issues with a single disk should not cause the server to reboot, so you may have some corruption in your actual array. If you check the controller log, you may see references to a "puncture".
