I tried adding a pair of 4TB WD RE disks to a HP Proliant ML350 G6 server, but the ACU utility shows them as having a capacity of 0.0 GB.
Is this a known issue? From the documentation for the Smart Array P410 Controller, I believe it should support 4TB drives. I am not planning on using them as a boot drive either, just to add some RAID1 storage to the box.
