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 John Pittman 2018-06-04 20:30:24 UTC

Description of problem:

The --allow option is present in the 'mpathconf --help' menu, but there is no description in the man page.

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

device-mapper-multipath-0.4.9-119.el7.x86_64

Steps to Reproduce:

Run 'man mpathconf' and check for --allow option

Actual results:

No explanation

Expected results:

Explanation of option in the man page, including the expected way to specify more than one wwid to allow (this is what I was looking for in the man page).

Comment 2 Ben Marzinski 2018-06-22 16:21:15 UTC

The man page has been updated to describe --allow as well as --outfile

Comment 4 Lin Li 2018-07-26 17:04:08 UTC

Verified on device-mapper-multipath-0.4.9-121.el7
[root@storageqe-06 ~]# rpm -qa | grep multipath
device-mapper-multipath-libs-0.4.9-121.el7.x86_64
device-mapper-multipath-0.4.9-121.el7.x86_64

Run 'man mpathconf' and check for --allow option
       --allow <device>
              Modifies  the  /etc/multipath/conf  blacklist  to
              blacklist  all wwids and the blacklist_exceptions
              to whitelist <device>. <device>  can  be  in  the
              form  of  MAJOR:MINOR,  a  wwid, or the name of a
              device-mapper device, either a multipath  device,
              or  any  device  on stacked on top of one or more
              multipath devices. This command can be used  mul‐
              tiple  times  to  allow  multiple devices.  NOTE:
              This action will create a configuration file that
              mpathconf  will not be able to revert back to its
              previous state. Because  of  this,  --outfile  is
              required when using --allow.
       --outfile <filename>
              Write the resulting multipath configuration to <filename>
              instead of /etc/multipath.conf.


Test result: The man page has been updated to describe --allow as well as --outfile
