Description Nikola Dipanov 2015-12-29 13:01:38 UTC 
Description of problem:

As per the bug #1203160 - invocation described in the doc text is wrong. Doc text suggests:

$ nova-manage migrate-rhos-6-pci-device-data

while the actual call should be

$ nova-manage db migrate_rhos_6_pci_device_data --max-number X

where X is the maximum number of device to be migrated in one run.

This will be valid only after #1274625 is fixed.

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

All rhos 7 versions before openstack-nova-2015.1.2-12.el7ost

Assigning to Martin for review.

Martin - this should be a quick fix; no need for QA on this one.

Updated doctext in BZ#1203160:

----
After fully upgrading to Red Hat Enterprise Linux OpenStack Platform 7 from version 6 (and all nodes are running version 7 code), you should start a background migration of PCI device NUMA node information from the old location to the new location. Version 7 conductor nodes will do this automatically when necessary, but the rest of the idle data needs to be migrated in the background. This is critical to complete before the version 8 release, where support for the old location will be dropped. Use '$ nova-manage db migrate_rhos_6_pci_device_data --max-number X' to perform this transition (where X is the maximum number of devices to be migrated in one run).
Note that this is relevant only for users making use of the PCI pass-through features of Compute.
