Special thanks to Gobinda for finding out this issue
Comment 3 SATHEESARAN 2020-05-01 11:35:10 UTC 
Tested with cockpit-ovirt-dashboard-0.14.5-1.el8ev.noarch with the following steps:

1. Started the RHHI-V deployment from web console
2. Provided the values for hosts, volumes.
3. On the bricks tab, with the default 'blacklist gluster devices' enabled,
also enabled 'lvmcache' SSD device as '/dev/sdg' and provided the details.

The generated inventory file included this LVM device also under blacklist_mpath_devices

[root@ ~]# grep blacklist_mpath /etc/ansible/hc_wizard_inventory.yml -A5
      blacklist_mpath_devices:
        - sdb
        - sdc
        - sdd
        - sdg
