Comment 0 for bug 1863983

Image upload is failing with NoFibreChannelVolumeDeviceFound error after configuring cinder backend (HP3Par FC storage) for the glance service.

The issue here we are facing is that usually cinder calls os_brick with multipath info but in this case glance is doing the call (without passing any multipath info). Cinder driver of glance_store passes 'hard-coded' False as multipath is not used to os_brick library.

In order to fix this we need to add new config option for cinder driver of glance_store 'multipath_enabled' True|False to avoid such issues.

Steps to reproduce:

1. Configure cinder back end(HP3Par FC storage) for the Image service
2. Create image
$ glance image-create --name "cirros2" --file cirros-0.3.0-i386-disk.img --disk-format qcow2 --container-format bare

Output:
500 Internal Server Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500)
