yes, storage info are stored in /etc/ovirt-hosted-engine/hosted-engine.conf.
By the way, if you want to propagate the info on new hypervisors when you run deploy on them, you should also update the answer file in
/etc/ovirt-hosted-engine/answers.conf so it will be configured automatically in newly installed hypervisors
