JOnathan539,   This would be dependent on the configuration, as well as the state of the disk in question. If the drive in question is Online, but indicating a Predicted Failure, you would need to Force Offline that drive prior to replacement. A predicted failure often is displayed on the drive by the lights going from red to green and back again or from Openmanage. Now if the drive is already failed, and it is a backplane system, it would be just removing the failed drive, wait 20 seconds, then insert its replacement. The rebuild of the failed drive should start automatically, but if it doesn't then you just assign the replacement as a hotspare and that will initiate the rebuild. Now if the drives are cabled, it would require shutting down the server and replacing the drive.     Let me know if this helps.
Hi All,  Can someone outline the proper procedure for replacing a failed HDD in a RAID 5 Array on a PE T430 with a PERC H330 RAID Adapter? Thank you in advance,
