Volume type support for both HP 3PAR drivers includes the ability to set the following capabilities in the OpenStack Cinder API cinder.api.contrib.types_extra_specs volume type extra specs extension module:

  • hp3par:cpg

  • hp3par:snap_cpg

  • hp3par:provisioning

  • hp3par:persona

  • hp3par:vvs

  • qos:maxBWS

  • qos:maxIOPS

To work with the default filter scheduler, the key values are case sensitive and scoped with hp3par: or qos:. For information about how to set the key-value pairs and associate them with a volume type, run the following command: 

$ 
            cinder help type-key

[Note]Note

Volumes that are cloned only support extra specs keys cpg, snap_cpg, provisioning and vvs. The others are ignored. In addition the comments section of the cloned volume in the HP 3PAR StoreServ storage array is not populated.

The following keys require that the HP 3PAR StoreServ storage array has a Priority Optimization license installed.

  • hp3par:vvs - The virtual volume set name that has been predefined by the Administrator with Quality of Service (QoS) rules associated to it. If you specify hp3par:vvs, the qos:maxIOPS and qos:maxBWS settings are ignored.

  • qos:maxBWS - The QoS I/O issue count rate limit in MBs. If not set, the I/O issue bandwidth rate has no limit.

  • qos:maxIOPS - The QoS I/O issue count rate limit. If not set, the I/O issue count rate has no limit.

If volume types are not used or a particular key is not set for a volume type, the following defaults are used.

  • hp3par:cpg - Defaults to the hp3par_cpg setting in the cinder.conf file.

  • hp3par:snap_cpg - Defaults to the hp3par_snap setting in the cinder.conf file. If hp3par_snap is not set, it defaults to the hp3par_cpg setting.

  • hp3par:provisioning - Defaults to thin provisioning, the valid values are thin and full.

  • hp3par:persona - Defaults to the 1 – Generic persona. The valid values are, 1 – Generic, 2 - Generic-ALUA, 6 - Generic-legacy, 7 - HPUX-legacy, 8 - AIX-legacy, 9 – EGENERA, 10 - ONTAP-legacy, 11 – VMware, and 12 - OpenVMS.
