I am using Brocade FC switch in my OpenStack environment. I have a question about OpenStack cinder zonemanger driver.

I find that [fc-zone-manager] can only configure one zone driver. If I want to use two FC switches from different vendors at the same time.

One is Brocade FC switch, the other one is Cisco FC switch. Is there a method or solution configure two FC switch zone driver in one cinder.conf ?

I want them both to support Zone Manager.

Unfortunately that is not possible. You are correct that only one zone driver can be configured. There isn't a lot of attention to the zone manager code these days - though FC just won't die! :) - but if you are motivated enough, you could try implementing multi-driver support. https://opendev.org/openstack/cinder/src/branch/master/cinder/zonemanager I don't know if this would help, or make it worse, but here is the change that added multibackend support for volume drivers: https://opendev.org/openstack/cinder/commit/6c708d12f58eb20fce6733f1f6fd08d9...
