Fixed In Version: openstack-ironic-python-agent-1.5.2-4.el7ost python-ironic-lib-2.1.3-2.el7ost
Doc Type: Enhancement
Doc Text:
With this update, bare metal node introspection reports both the /dev/XXX block device name and the /dev/disk/by-path/XXX name. Unlike the /dev/XXX name, the /dev/disk/by-path/XXX name does not change at system reboot and may be the same across similarly configured hardware. This update improves reliability of deployments by using /dev/disk/by-path/XXX information in the cloud configuration.

Comment 2 Sean Merrow 2018-04-09 19:49:29 UTC
This request is to backport the RFE of which this is a clone of, to OSP 10.

Comment 3 Ilya Etingof 2018-04-25 21:48:17 UTC
I have tested this backport on OSP10 - seems to work:

$ openstack baremetal introspection start controller-0
$ openstack baremetal introspection data save controller-0 | python -m json.tool
       "disks": [
                "by_path": "/dev/disk/by-path/pci-0000:00:08.0",
                "model": "",
                "name": "/dev/vda",
                "rotational": true,
                "serial": null,
                "size": 32212254720,

                "wwn_vendor_extension": null,

Verfied Gerrit changes were commited.  Ran openstack baremetal intorspection data save $UUID | jq '.inventory.disks' 

verified output shows the /dev/disk/ in the output.  Please reopen if issue is still present.
