I was wondering how one can add a drive into an existing RAID array while ESXi is still running. I have read that you are able to use Dell OpenManage to do this. I have installed OMSA 7.0 on the VMWare ESXi host (5.0 and fully updated) and I've installed OpenManage Essentials on a Windows Server 2008 R2 guest. The issue that I'm having is that OpenManage is unable to see my RAID controller. I have seen videos and photos as parts of guides on how to do this online, so I would assume that the functionality exists and I just have it set up wrong.

You already asked this question… but I closed that as a dupe of this one for you – Iain Jun 27 '12 at 20:06
Okay, thanks. I was not sure how to delete the old one but i wanted to re-post as i didn't even get 1 reply before. – yoyomommy Jun 27 '12 at 20:45
@yoyomommy What kind of RAID controller is it? – Shane Madden Jun 28 '12 at 0:30

It would be helpful to know the RAID controller, but I think this may be a limitation of OME+ESXi as discussed here. It's possible you can manage the storage via OMSA Managed Node (as opposed to OME) from the Windows box.
