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.

Fixed In Version: device-mapper-multipath-0.4.9-80.el6_6.2
Doc Type: Bug Fix
Doc Text:
Previously, the first time the multipath utility recognized a path device, the path device was not claimed in the udev utility, and other programs could race multipath to claim it. As a consequence, multipath systems could fail to boot during installation. With this update, the multipathd daemon now checks the kernel command line on startup. If it has recognized any parameters with a World Wide Identifier (WWID) value, it adds those WWIDs to the list of multipath WWIDs. Devices with those WWIDs are thus claimed the first time they are recognized. As a result, if multipath systems do not boot successfully during installation, users can add mpath.wwid=[WWID] to the kernel command line to work around the problem.
