Hello,
FDE drives are not supported with an MSA P2000. Additionally, if the drives are secured there will be no way to unsecured them unless you have the encrytpion key.
HPE systems (both storage and servers) generally use HPE firmware on their drives. I am not certain about NetApp, but it is likely the same scenario. This vendor specific fimrware will limit the ability to transport drives between different companies hardware.
Cheers,
Shawn
