This configuration has two NFS servers and one NFS package,
One server is the primary node and the other server is the adoptive
node for the NFS package. As shown in Figure 3-7 this sample configuration enables the File Lock
Migration Feature.
Figure 3-8 shows the same
configuration after one primary server has failed. Figure 3-6 shows this sample configuration
after host basil has failed. Host sage has adopted pkg02.

Package Control Script for pkg01
This section shows the package control script (pkg01.cntl) for the package pkg01 in this sample configuration.
Only the user-configured part of the script is shown; the executable
part of the script and most of the comments have been omitted.

function customer_defined_run_cmds
{ $HA_APP_SCRIPT lock_migration:${IP[0]}
test_return 51
} |
The function customer_defined_run_cmds calls
the toolkit.sh script with lock_migration:<IP_address> parameter for file lock migration. The argument to be passed to
the HA_APP_SCRIPT for lock migration should contain
the same name or IP address used by the clients while mounting the
exported file system.
