I had this same issue of nbcertcmd failing with status 8500.
In my case firewall was blocking 1556 and 13724 from the client to the backup servers.
After opening the ports, I was able to issue the certs and is working now.
Guessing by name oracledmz, this client is behind a firewall with no direct connection to the master server hence nbcertcmd -ping does not work and unable to obtain a host ID certificate. You need to either allow communication between the client and master server through the firewall and retry the installation or obtain the certificate manually (see https://www.veritas.com/support/en_US/article.100039650.html) or use a media server in DMZ to provision it, this is what the installation script is asking
