NFS Control Scripts for pkg02

The nfs.cntl Control Script

This section shows the NFS control script (nfs2.cntl) for the pkg02 package 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 are omitted.

function customer_defined_run_cmds

{

/etc/cmcluster/nfs/nfs2_xmnt start

remsh thyme /etc/cmcluster/nfs/nfs2_xmnt start

}

The function customer_defined_run_cmds calls a script called nfs2_xmnt. This script NFS-mounts the file system exported by the package pkg02. If you configured the file system in the /etc/fstab file, the package might not be active yet when the servers tried to mount the file system at system boot. By configuring the NFS control script to NFS-mount the file system, you ensure that the package is active before the mount command is invoked.
