I have a poweredge r415. There are 4 front-bays, 2 of which are occupied by 300gb SAS drives configured in a raid0 array.
I would like to add a SATA drive to the third bay so that I can perform backups to it; so it would not be part of the RAID array and would be seen as /dev/sdb or whatever by the OS.
I already have a drive and a caddy lying around and have installed it but cannot see it in the OS.
I assume this is because of the backplane and raid controller and am starting to think this isn't possible.
Is this possible? Do I need to enabled a specific 'sata port' in the bios?
Any help is greatly appreciated, thanks!
