127.0.0.1 loopback localhost
192.168.5.11 mclnode2-adm mclnode2
Above is one of Our HACMP Cluster node(two node HACMP) /etc/hosts file. Please let us know are there are any errors in that.
“_” were used in the host name for server ip “10.1.1.26”, I think underscore is not allowed in hostnames.
eg: 10.1.1.26 mclnode2_boot1
I doubt using dash character in hostname
I think in the entry “192.168.5.11 mohclnode2-adm mohclnode2” is wrong it should be like
eg: “192.168.5.11 mclnode2-adm.abc.com mclnode2-adm”

Re: need help to verify /etc/hosts file2012-02-22T06:14:02ZThis is the accepted answer. This is the accepted answer.By the RFC you can use only leters, numbers and dash in host name and (as I remember) you cant start the hostname with dash. So your supposition is correct. Will be wise to follow the rules, because some software will not run on the machine with such hostname
