What are the steps to replacing a hard drive in a RAID on a Dell Power Edge T620?
There are four hard drives. I believe it is a RAID 10 configuration. Two of the four hard drives are blinking an amber light in addition to the green light. I believe that indicates imminent failure and that is why I'm asking about replacing them. The customer has two identical hard drives installed that are brand new but not part of the RAID. Is it simply a matter of pulling the "bad" drives out and replacing them with the spares or must I configure the RAID in some way via software or BIOS?
However, when I put in my credentials, it pauses for a few seconds and prompts me for the information again.
Did I perhaps download the wrong program or maybe miss some fundamental step?
yes..flashing both means predictive failure
if there are 2 identical drives just like the others sitting there doing nothing, you need to assign those drives as global hot spares. once that is done, you need to mark the predictive failing drives as failed which will trigger a rebuild on the hot spare. however, you must only do one at a time else you risk losing the entire array if both failing drives are part of the same stripe set. make sure you have a good backup before doing any of this in case something goes wrong.
once one drive is completely done rebuilding and is healthy, you can mark the other drive as failed which will trigger a rebuild on the other hot spare. the time it takes for a rebuild depends on a number of factors including drive speed, size and load on the server
this can be done either with OMSA (which OS is on this system?) or by rebooting and going to the controller during POST
