I have a Penguin Server with 6 1TB Seagate drives in a RAID 5 configuration. One of the drives failed during a power outage. What are the criteria for replacing the failed drive (size, manufacturer, etc)?
If you have a decent raid engine, all you have to do it insert a NEW drive - prefer a same model, same firmware...but bigger and same type still work
If the rebuilt function auto is enable - Insert the HDD while raid is running, it should rebuilt.
Some raid controllers need to set the NEW HDD as hot spare before it can rebuilt.
So look at the raid GUI, after insert the HDD you should be able to figure it out
As long as you did not initialize/delete an array, you should be safe to explore the RAID manager to rebuilt the raid
