R720XD with H710p controller. Drive is a Dell 600B SED drive P/N: YJTKX , Drive is used if that makes a difference. Upgraded firmware on controller to 21.3.4-0001. Drive shows blocked. Only option available in controller screen is under security I am able to create and delete security keys so don't think that is the issue. On the drive itself only option available is to blick the led. Tried resetting controller to factory default. This is just a test server so this is the only drive I have in it at the moment.
Any Ideas?
