HPE 3PAR Fibre Channel and iSCSI drivers in Configuration Reference

[Bernd Bausch]

The 3par driver page misses an important detail: The user configured in cinder.conf needs not only the edit role, but must also have a domain setting of "all".

This is mentioned in the HPE white paper "OpenStack HPE 3PAR StoreServ Block Storage Driver Configuration Best Practices", but not on this page.

I'm afraid it's not a bug. The following paragraph is mentioned in the HPE white paper "OpenStack HPE 3PAR StoreServ Block Storage Driver Configuration Best Practices", too.

CPGs used by the HPE 3PAR StoreServ Block Storage Drivers are no longer required to belong to a domain. The "hp3par_domain" configuration setting in the cinder.conf file has been removed.

[Chason Chan (chen-xing)]

Another paragraph:

The hp3par_domain in the cinder.conf file has been deprecated in the Havana release and removed in the Icehouse release. The driver now looks up the domain based on the CPG specified in either the cinder.conf file (or hp3par:cpg extra-spec volume type setting prior to Kilo only).

[Bernd Bausch (berndbausch)]

Nevertheless, the user configured in cinder.conf needs not only the edit role, but must also have a
domain setting of "all". As documented in HPE's white paper: "The drivers username credentials can have an “edit” role and domain set to “all”, the drivers no longer require a “super” role."

[Chason Chan (chen-xing)]

It should be fixed in the cinder.conf locate in Cinder project first, then we can fix it in openstack-manuals.
