The hanfs.sh Control Script
This section shows the NFS control script (hanfs2.sh) for the pkg02 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 enables the File Lock
Migration feature.

NFS File Lock Migration and Monitor Scripts for pkg02
The nfs.flm Script
This section shows the NFS File Lock Migration (nfs2.flm) script for the pkg02 package in
this sample configuration. This example includes only the user-configured part of the script; the
executable part of the script and comments are omitted.

The nfs.mon Script
This section shows the NFS Monitor (nfs2.mon) script for the pkg02 package in this sample
configuration. This example includes only the file lock migration related part of the script; the
remaining script is omitted.
NFS_FILE_LOCK_MIGRATION=1

Example Three - Three-Server Cascading Failover
This configuration has two packages and three servers. One server is the primary node for both
packages. The other servers are adoptive nodes for the two packages. Figure 5-5 illustrates this
configuration. Dotted lines indicate which servers are adoptive nodes for the packages.
