RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Bugzilla 1695343 0 medium CLOSED lshw does not list NVMe storage devices as "disk" nodes 2023-04-29 10:49:04 UTC

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.
