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.

Description Bryan Gurney 2019-04-02 20:49:40 UTC 
Description of problem:
lshw currently does not list NVMe solid state drives as "disk" nodes.

Currently, for each NVMe device, lshw shows the "storage" node, which details the capabilities of the NVMe "controller", but it does not show a "disk" node, which details the size of the device.  This means that users of lshw (including beaker) will not be able to determine the device's size.

Version-Release number of selected component (if applicable):
lshw-B.02.18-12.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. Install RHEL 7.6 on a system with at least one NVMe solid state drive.

Actual results:
lshw lists each NVMe device as a "storage" node under "pci", but there is no corresponding "disk" node.

Expected results:
lshw lists each NVMe device as a "storage" node under "pci", and each NVMe device has a corresponding "disk" node.

Additional info:

Here's a quick example of the current results:

Thanks.
Comment 14 Jeff Bastian 2020-01-03 19:16:42 UTC 
This is partially fixed for RHEL-7.8: NVMe drives now have an nvme node in lshw output as shown below.  The node is still missing the disk size, though.  More work is needed upstream to fix this.  We're tracking this in bug 1763316 for RHEL8; it can possibly be backported to RHEL7 when it's ready.  I'll move this bug to VERIFIED and we'll continue the work in bug 1763316.
