we had a 1TB Seagate SAS drive go bad in a Dell PowerEdge. We purchased a matching drive from Amazon and replaced in the server. The drive shows READY - but we can't seemingly add the drive back into the RAID array. The only option we get when selecting F2 (Operations) is to "Make Global HS"....we can't move the cursor to Replace or Rebuild options on the menu. any help greatly appreciated!
