You'll want to connect using the host's IP address, not the iDRAC IP. 2 commons issues I see when trying to connect to a new OMSA instance on ESXi is that the host doesn't get rebooted after installing the package, and the other is trying to access the host's OMSA instance from a VM on the host. Would either of these apply here?
I currently have a dell R620 server, with 1 raid1 SSD setup as a virtual disk. I want to add another SSD to this system, to be accessible from esxi that's running on this server.  To be clear: I don't want to expand the existing raid, I want to add this single drive as a new virtual disk (because this is the only way esxi will be able to "see" this disk?) As this will be a single SSD drive, only stripe(0) is possible, but as far as I can find, the only way to add a new virtual disk, is trough the PERC configuration tool when booting the server? As this server is running esxi with a lot of VM's, if there is a possibillity to create a virtual disk without having to reboot, this would be nice.   Any ideas here?
