Good to hear you're starting to work with server set ups, if you're into tech stuff you'll find it a very interesting.
Regarding your questions, It is very important to bear in mind that the idea of having a drive array is to provide redundancy on the data stored in those drives, in any of the cases as soon as a drive is shown as failed it most be replaced as soon as possible once the drive is replaced the raid manager (software or hardware) in most cases will start rebuilding the array with the new drive automatically bringing it back online, please note that raids 1 and 5 will support up to 1 drive failure at the time meaning that if 1 of the other members fails data will be lost, raid 6 could support up to 2 drives failed under certain circumstances, which means the top priority in these scenarios is to replace the failed drives as soon as it is possible. Then when the array is shown as degraded it normally is because one drive is under predictive failure status (it is online but will fail soon) or one of its raid partners is missing or failed and it will come back to normal once that status is corrected.
