NFS Control Scripts for pkg01
The nfs.cntl Control Script
This section shows the NFS control script (nfs1.cntl) for the pkg01
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.
PATH=/sbin:/usr/bin:/usr/sbin:/etc:/bin

VXVOL="vxvol -g \$DiskGroup startall" #Default
FS_UMOUNT_COUNT=1
FS_MOUNT_RETRY_COUNT=0

function customer_defined_run_cmds
{
/etc/cmcluster/nfs/nfs1_xmnt start
remsh basil /etc/cmcluster/nfs/nfs1_xmnt start
}
The function customer_defined_run_cmds calls a script called
nfs1_xmnt. This script NFS-mounts the file system exported by the
package pkg01. 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.
