PCPKTech,   With the images you provided, as well as a translator, it appears that 0:1:0 is in a Ready state, and isn't Online. So there wouldn't be a need to force it offline, as it isn't showing currently in the Virtual Disk. Would you confirm if you are seeing the dirve listed as Foreign anywhere?   That being said, what I suggest you start with is updating the servers BIOS, iDrac, and the H710 to current. Then see ifthe situation and information is the same, if so then you should be fine removing and replacing, but lets confirm that after updating.   Let me know what you see.  
Hello, we have a Dell PowerEdge R320 Server with a PERC H710 Mini Controller which reports a soon to fail RAID10 Member (0:1:0). We have 4x 300GB 2,5" SAS Drives connected to 0:1:0, 0:1:1, 0:1:2 and 0:1:3 at the backpane. The operating system is a Windows Server 2012 R2 Standard and the Dell OMSA is v7.4.0 [IMAGE][IMAGE] I already received two spare drives and would now like to know how to replace the drives, if possible without shutting down the server. In the menu at the screenshot I can only select the task to let the tray blink which houses the member disk. Do I just pull it out and replace it? I found no possibility to take it offline.   Thanks in advance and let me know if you need additional Information.
