errcode=00000, errmsg=Unexpected error: <Exception: ha_check_hostname_ip
failed:<Exception: check srv('192.168.2.21') hostname/IP failed! => <Exception: Invalid hostname/IP configuration: hostname=OracleVM;ip=127.0.0.1>
its not a HA server, we didnt enable the HA
Pls helo me

Answer 1

You do not need to setup or configure a DNS server in a private LAN, unless you want to be reachable beyond your local home network. The local hosts file provides the same functions in terms of mapping a TCP/IP number to a name and vice versa like a DNS server. It is not designed to maintain large corporate networks with dynamic IP addresses, but easy to maintain in your small home network. Your DSL modem is most likely the a gateway for all internet traffic outside your private LAN and also re-routing DNS requests for public host resolving. Unless you explicitly configured an authoritative internet domain name for your home LAN on your DSL modem your computers may not have been assigned internet host and domainname via DHCP.
To analyze your current situation you can use the following commands:
# hostname
If this shows something like "localhost.local" this means you do not have given your computer a hostname and domainname and it is using defaults.
# domainname
It will be "blank" if not configured.
# ping localhost.local
This should show resolve in your real IP address like 192.168.2.1, but will show nothing if DNS or /etc/hosts is not configured properly.
# ping localhost
This should result in 127.0.0.1, which is a looback interface of the TCP/IP stack.
You need to make appropriate entries in your /etc/hosts file if you cannot use a DNS server.
192.168.2.1 localhost.local ovmserver
127.0.0.1 localhost
If this does not resolve the issue you can try the below. This is not a very clean configuration, but could work.
192.168.2.1 localhost.local ovmserver localhost
127.0.0.1 localhost
If you have any entry like:
127.0.0.1 ovmserver - this is wrong and needs to be removed.
Be aware of possible network address translation if you use VMware, in which case you need to configure your VMware network interface accordingly.
BTW: Error status on newly created pool
