Once again, the logs were not collected with DEBUG enabled. Please enable DEBUG and collect the cinder-volume logs.

My understanding is the os-brick package was a hotfix. Was the hotfix installed by customizing the cinder-volume container image on the director, followed by having the director deploying the hotfixed c-vol image? Or was the os-brick RPM patched into the running c-vol container? I ask because I'd like to confirm the c-vol process was restarted after the os-brick RPM was updated.

The symptoms match a known problem with the 3par driver [1]. The LP bug
describes a situation where the FC zoning doesn't allow the controller to
access all target ports on the 3par backend, and the 3par driver happens
to pick a port that isn't accessible.

[1] https://bugs.launchpad.net/cinder/+bug/1809249

Per LP bug, a workaround is to set use_multipath_for_image_xfer=True, which 
will force the driver to scan all ports.

If setting use_multipath_for_image_xfer=True doesn't correct the problem, then
we may need to get HPE involved. If that's necessary, then please set
hpe3par_debug=True and capture more cinder-volume logs.
