Hi, With reference of your tweet in twitter, I have replied on your enquiry. Check it out. Let me know.  
Hello All, I ask how to test that my Raid 1 installed and working good? And if I use OMSA tool, how to no that? I was test it by unplug one hard drive and work with only one and it was working. After i plug the second one with the first one it was missing and i make rebuild, now both are online and work. But to be sure?  Thanks
