I have PowerVault MD 3200 and I expanded it by PowerVault MD1200
When I connect MD 1200 it doesn't show up on Storage Manager and I get error message in Event log says that"Physical physical disk has unsupported capacity" message is repeated by each slot no.
My MD1200 consist of 12 Dell Hard Disks (SAS 12Gbps - 512e - RPM 7.2K - 6 TB)
I even tried to put single HD with 6 TB but didn't work out so, I know that it seems unsupported Hard Disk capacity but, having read the specification sheet for MD1200 it confirm that it support up to 10 TB.
