The unload script from the generic file system template should appear similar to the following
script. Modify the variable values in the definition lines. For an example of the customized
unload script, see
Section 11.5.2, “Sample Unload Script for the Linux POSIX Volume Cluster
Resource,” on page 175 .

2 Below the script editing area, specify the Unload Script Timeout value, then click Next .
The timeout value determines how much time the script is given to complete. If the script does
not complete within the specified time, the resource becomes comatose when migrating to
another node. Cluster Services marks the process as failed right after the defined timeout
expires, but it must wait for the process to conclude before it can start other resource
operations.
3 Continue with Section 11.3.5, “Enabling Monitoring and Configuring a Monitor Script for a
Linux POSIX Volume Cluster Resource,” on page 166 .
11.3.5 Enabling Monitoring and Configuring a Monitor Script
for a Linux POSIX Volume Cluster Resource
The cluster resource monitor script specifies the commands to monitor the cluster resource.
The generic file system template you specified in Step 6 when you created the cluster resource
contains a monitor script that you must edit to supply information specific to your file system
resource. Use the same values for the defined variables that you used in the load script in
Section 11.3.3, “Configuring a Load Script for a Linux POSIX Volume Cluster Resource,” on
page 164
