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 Product Errata RHBA-2017:1961 0 normal SHIPPED_LIVE device-mapper-multipath bug fix and enhancement update 2017-08-01 17:56:09 UTC

Description John Pittman 2017-03-09 20:44:31 UTC
Created attachment 1261696 [details]
patch editing multipath.conf.defaults and hwtable.c

Description of problem:

There are 6 different listings for the Dell 3xxxxx family in the hardware table, and they all have the same settings.  These should be combined using regex in .product line.  This will provide ease of use/viewing in multipath.conf.defaults, multipath.conf,  hwtable.c, and the 'multipath -t' command.

Version-Release number of selected component (if applicable):

device-mapper-multipath-0.4.9-103.el7

How reproducible:

Run 'multipath -t' and observe Dell 3xxxxx hardware table defaults.

Actual results:

6 separate listings

Expected results:

1 listing

Comment 2 Ben Marzinski 2017-03-10 20:13:44 UTC
I don't see a problem with this. However, upstream has already combined them (and some additional devices) into three configs (still identical) based on devices that share the same firmware. I'll ask upstream if anyone objects to combining them further, and I'll pull whatever the upstream result is back into RHEL.

Comment 5 Ben Marzinski 2017-04-25 21:12:46 UTC
Nobody upstream objected to combining them, so I'm fine it. I've also updated the config to use the upstream no_path_retry value (30 checks instead of 15), and changed the product regex to allow the MD38xxx devices as well.
