Hello. Yes, take it offline before swapping it out with a replacement drive. Monitor the automatic rebuild process within OpenManage. If it does not automatically rebuild, assign the drive as a hot spare.
I have a Power Edge R420 with a Perc H310 mini and 3 disk raid 5 configuration. One of my disks is flashing amber with a "failure predicted" message in open manage administrator. Do I have to take the failed drive offline before replacing it? Thanks
