Can we have attribute like misc_nova in cinder?

[shuo zhang]

I am going to set these attributes in cinder.conf:
storwize_svc_volpool_name, storwize_svc_vol_iogrp, storwize_svc_connection_protocol
But since I am using another volume-driver different from the ones conditioned in cinder.conf.erb, I cannot set these attributes.

So, can we add some attribute like misc_cinder to let me set these attributes?
Or I have to change the cinder.conf.erb to add our driver to it. Can you accept it?

openstack-block-storage/templates/default/cinder.conf.erb

add:

<% if node["openstack"]["block-storage"]["volume"]["driver"] == "cinder.volume.drivers.zvm.storwize_svc.StorwizeSVCZVMDriver" %>
######## defined in cinder.volume.zvm.storwize_svc ########

storwize_svc_volpool_name=<%= node["openstack"]["block-storage"]["storwize"]["storwize_svc_volpool_name"] %>
#### (StrOpt) Storage system storage pool for volumes

# The I/O group in which to allocate volumes (integer value)
storwize_svc_vol_iogrp=<%= node["openstack"]["block-storage"]["storwize"]["storwize_svc_vol_iogrp"] %>

# Connection protocol (iSCSI/FC) (string value)
storwize_svc_connection_protocol=<%= node["openstack"]["block-storage"]["storwize"]["storwize_svc_connection_protocol"] %>
<% end %>
