Open Stack

Hi, I'm sorry if I reopen this thread, but I cannot find a solution at the
moment. Please, can someone give me some hint on how to detect megaraid
controllers with IPA? I think this could be useful for many users.
PS: I can do any test, I have a 6 servers test environment (5 nodes +
undercloud) with megaraid controllers (Poweredge R620)
Thank you
