2.5 Support for Multiple Network Interfaces on UNIX Hosts

If any ClearCase host (client or server) running UNIX has two or more network interfaces (two or more separate lines in the /etc/hosts file or the hosts NIS map), you must create a file on that host, /var/adm/atria/config/alternate_hostnames, which lists each of its host names. For example, suppose that the /etc/hosts file includes these entries:

.
.
159.0.10.16 widget sun-005 wid
.
159.0.16.103 widget-gte sun-105
.

In this case, the alternate_hostnames file on this host must contain these entries:

widget
widget-gte

Note that only the first host name in each hosts entry must be included in the file. In general, the file must list each alternative host name on a separate line. There is no commenting facility; all lines are significant. If a host does not have multiple network interfaces, this file must not exist on that host.
