5.1.5 Installation fails on Aura7 NVMe device

Installation fails if the target device is an Aura7 NVMe add-in card with two block devices. Although the card has two independent NVMe controllers and devices, they are assigned identical WWIDs. The multipath device mapper maps the two block devices to the same WWID, resulting in a bogus multipath configuration that prevents installation.

The workaround for this issue is to disable multipath for the installation at boot time by using the installer boot argument nompath. After the installation completes, black list the NVMe block devices for the multipath configuration on the system by editing the /etc/multipath.conf file. Or, you can disable device mapper multipath altogether. See Oracle® Linux 7: Administrator's Guide for more information about configuring multipath.
