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 Lin Li 2021-07-15 09:00:53 UTC 
Description of problem:
[power9]multipath.conf has usage typo error for checker_timeout

Version-Release number of selected component (if applicable):
device-mapper-multipath-0.8.4-14.el8.ppc64le

How reproducible:
always

Steps to Reproduce:
1.[root@ibm-p9z-20-lp13 ~]# rpm -qa | grep multipath
device-mapper-multipath-libs-0.8.4-14.el8.ppc64le
device-mapper-multipath-0.8.4-14.el8.ppc64le
2.[root@ibm-p9z-20-lp13 ~]# man multipath.conf
       checker_timeout  Specify the timeout to use for path checkers and prioritizers, in sec-
                        onds.  Only prioritizers that issue scsi commands use checker_timeout.
                        Checkers  that  support  an asynchronous mode (tur and directio), will
                        return shortly after being called by multipathd, regardless of whether
                        the  storage  array  responds.  If the storage array hasn't responded,
                        mulitpathd will check for a response every second, until checker_time-
                        out seconds have elapsed.

                        The default is: in /sys/block/sd<x>/device/timeout


Actual results:
mulitpathd will check......

Expected results:
multipathd will check

Comment 1 Lin Li 2021-07-15 09:17:06 UTC 
I found the issue on IBM power9 server. But I guess the issue exists all arches.
Comment 2 Ben Marzinski 2021-07-26 16:55:09 UTC 
Typo fixed.
