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.

Summary:	[Nimble Storage] Add APTPL flag to fence_mpath and make multipath-tools honor APTPL bit on registrations

Fixed In Version:	device-mapper-multipath-0.4.9-120.el7	Doc Type:	Bug Fix
Doc Text:	multipathd can now correctly set APTPL when registering keys on path devices Previously, the multipathd service did not track which devices registered their persistent reservation keys with the Activate Persist Through Power Loss (APTPL) option. As a consequence, registrations always lost the APTPL setting. With this update, the problem has been fixed: * If you set the "reservation_key" option to a file in the `multipath.conf` configuration file, multipathd now keeps the APTPL setting automatically. * If you set "reservation_key" to a specific key, you can now add the ":aptpl" string at the end of the key in "reservation_key", which enables APTPL for it. Set this to match the APTPL setting used when registering the key.	Story Points:	---

Hello shivamerla1,
Because there is no Nimble Storage in our lab, could you help provide test result once the package is available?
thanks!

Comment 4 Ben Marzinski 2018-06-13 14:29:09 UTC

Multipath now supports an optional extension to the reservation_key parameter. You can now set reservation_key to "<key>:aptpl".  This will inform multipathd to set the APTPL bit when registering keys on paths, when they come back up. For this to work correctly, you must also set --param-aptpl when using mpathpersist to register the key. If you set reservation_key to "file", multipath will automatically track which devices need the APTPL bit set by multipathd, depending on which devices you register keys with using the --param-aptpl option
for mpathpersist.

Hi shivamerla1,
Could you test if the new option works well on Nimble Storage? 
Thanks in advance!
