Replacing failed disk

Hi,
I have a 36 disk dss v6 server with 2 x 17 disk RAID6 arrays and 2 global hotspares.

One disk failed but one of the global hotspares kicked in and rebuilt correctly.

I replaced the failed disk with a new one and it is now displaying as "good" in SETUP / H/W RAID.

However, under Physical Disk Configuration it says "Warning - Some of the disk are foreign" and under Foreign Configuration Restore I have options to Apply or Clear "Configuration:0" and/or" Configuration:all".

Please can you advise what actions I need to take to change the replacement disk from "good" to make it "online" so I can then make it my replacement Global Hotspare?

Thanks
