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-0.4.9-121.el7
Doc Type: Bug Fix
Doc Text:
The `multipathd readsector0` checker now returns the correct result Previously, in some cases the `multipathd` daemon was incorrectly calculating the I/O size to use with the `readsector0` checker, causing it to do a 0 size read. This could cause the `multipathd readsector0` checker to return the wrong result. It is also possible that some SCSI devices do not treat a 0 size read command as valid. With this fix, `multipathd` now uses the correct size for the `readsector0` checker.

Comment 5 Ben Marzinski 2018-06-22 17:08:36 UTC 
Multipathd will now request the correct number of blocks for the readsector0 checker in all cases.  I don't know if that's the root cause of this issue, but it should make the checker issue the correct command.  If the controller is still not honoring it, it is more likely a controller issue.
