5.1.3 Installation on an Aura7 NVMe device

Installation fails if the target device is an Aura7 NVMe add in card with 2 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.

To work around the issue, disable multipath at boot for the installation by using the installer boot argument nompath. After installation, blacklist the NVMe block devices for multipath configuration on the system by editing /etc/multipath.conf, or disable device mapper multipath altogether. See Oracle® Linux 7: Administrator's Guide for more information on configuring multipath. (Bug ID 27638939)
