Openmanage server administrator available task - "offline"

I am in Openmanage server administrator for my T320 server, the available task I am trying to accomplish is to take offline a "foreign" Dell W347K 600GB 15K SAS 3.5" OEM Hard Drive in Dell Hot Plug Tray. Inside the "Physical Disks on Controller PERC H710 Adapter", and "available tasks", I pull down the menu and it only allows "blink" and "unblink", but has no option of "offline" on any of the 4 drives I have.

I need to take the plug-n-play hard drive offline in order to replace it. I have a dell spare and ready, just need to get pas this bump in the road.
