Description Jeff Bastian 2019-04-11 19:30:35 UTC

Description of problem:
Some of the latest ARM servers (SmartNICs in particular like the Mellanox Bluefield) use MMC storage, but lshw does not report this as a disk.  As a result, tools like Beaker think the servers have no storage available.  Please report MMC storage as disks, too.

Version-Release number of selected component (if applicable):
lshw-B.02.18-16.el8

How reproducible:
always

Steps to Reproduce:
1. run lshw on a system with MMC for primary storage

Actual results:
no disks reported

Expected results:
/dev/mmcblk0 is reported as a disk

Additional info:
See also bug 1695343 for a similar problem with NVMe storage.

Comment 7 Jeff Bastian 2020-08-05 22:29:33 UTC

Verified with lshw-B.02.19.2-2.el8.
