I've got a Dell Poweredge 2850 up and running as our production Web Server. Its got a RAID 1 array for the OS, and a RAID 5 for data. I would like to add an additional drive on it's own (not a member of an array), for backups.
My main question, is since they are hot swappable trays, can I just slap this hard drive in while the server is up, during production hours? Or is the best practice to wait until off hours...and would I need to bring the server down for any reason?
Thanks for any input!
