The hanfs.sh Control Script
This section shows the NFS control script (hanfs3.sh) for the pkg03 package in this sample
configuration. This example includes only the user-configured part of the script; the executable
part of the script and most of the comments are omitted. This example does not enable the File
Lock Migration feature.

Example Two - One Adoptive Node for Two Packages with File Lock
Migration
This configuration has two packages, each owned by a different server. The adoptive node for
both packages is the same host. This sample configuration uses the package control option, which
prevents the adoptive node from adopting another package if it has already adopted one.
Figure 5-3 illustrates this configuration.
