Symptom:
Takes time to execute an operation command of a Redundant Line Control Function.
Takes time to activate a service or to switch nodes at the cluster operation.
Corrective action:
When a host name or an IP address specified in the information of a virtual interface, the monitor-to information, etc. is not described in /etc/hosts file, or when "files" are not specified at the top in an address solution of /etc/nsswitch.conf, occasionally it takes time to process an internally executed name-address conversion. Therefore, it takes time to execute a command, or for the cluster state to change. Check that all IP addresses and host names to use in a Redundant Line Control Function are described in /etc/hosts, and that /etc/hosts is referred first at name-address conversion. Also, enable the hostname resolution function (set by hanetparam -h), which allows you to change the host name to the IP address using only the /etc/hosts file without depending on the /etc/nsswitch.conf file setting.
