MD3000i in reset state (probably)

Hello,

we add one HD ST1000NM0045 (labeled Dell) to expand a VirtualDisk on our md3000i. A few seconds after the disk is inserted (warm), the md3000i goes offline, the steady orange led means "reset state".
Even with cold insert, same result. No led blinks on the disk.

First thing I thought it was a compatibility problem, but cannot find the HD Support matrix anymore. Purchasing manager told me he bought those disk from Dell, stressing they are for an md3000i.

Thank you.
