I had similar issues & had to rely on iLo or iDRAC.
The installation guide makes a reference to being unable to boot via CD, DVD, or USB; however, I haven't bothered looking into the aspects of UEFI & Secure Boot to understand what's prevent us from booting directly off a USB stick.

Best of luck,

Subject: Aruba Airwave 8.3 Installation issues
Has anyone had any luck installing Aruba Airwave version 8.3? I downloaded the installation ISO file, verified the checksum, and made a bootable USB with Rufus. The installation will start but gets stuck every time on a "Started cancel waiting for multipath siblings of sda" message. (Which appears to be a Red Hat bug.) I was running this on an Aruba AirWave DL360 Professional Edition Hardware Appliance, which is basically and DL360 Gen9. I was running in the LegacyBIOS boot mode but I've also tried it with UEFI boot mode with the same results. Is this why the 8.3 software has been hidden in the ASP portal filter? You can still get to the files directly from the link sent out in the weekly release email. Just curious if there's something else I should try before opening a support ticket.
