Serviceguard NFS Toolkit A.11.11.06, A.11.23.05 and A.11.31.07 Administrator's Guide (September 2010)

e. Comment out the failover_policy and failback_policy since this package will run on
each server and will not failover if a server fails.
# failover_policy configured_node
# failback_policy manual
f. Add node_name variables for each server in the cluster that will run the export package
(the order of the servers does not matter).
node_name thyme
node_name basil
g. Set the dependency_name, dependency_condition, and dependency_location variables
so that the export package will only run if the Serviceguard CFS multi-node packages
are already running. Since there are two CFS file systems in this example, there are also
two CFS multi-node packages.
dependency_name SG-CFS-MP-1-dep
dependency_condition SG-CFS-MP-1=up
dependency_location same_node
dependency_name SG-CFS-MP-2-dep
dependency_condition SG-CFS-MP-2=up
dependency_location same_node
h. Comment out the service_name, service_cmd, service_restart, service_fail_fast_enabled
and service_halt_timeout variables.
# service_name nfs.monitor
# service_cmd "$SGCONF/scripts/nfs/nfs_upcc.mon"
# service_restart none
# service_fail_fast_enabled no
# service_halt_timeout 0
NOTE: The NFS export multi-node package does not monitor exported file systems
(for example if a file system becomes unexported or inaccessible). It checks if the CFS
dependent packages have access to the file systems. If the NFS failover package loses
access and cannot read or write to the disk, it will fail (the exportfs multi-node package
will not fail).
Starting a Serviceguard NFS export package
Use the following procedure to start an export package.
1. Verify the cluster and package configuration files on each server.
# cmcheckconf -k -v –C /etc/cmcluster/cluster.conf –P /etc/cmcluster/nfs_modular/nfs-export.conf
2. Verify and apply the cluster package configuration files on a single server.
# cmapplyconf –v –C /etc/cmcluster/cluster.conf –P /etc/cmcluster/nfs_modular/nfs-export.conf
3. Run the export package on a single server with the following command:
# cmrunpkg –v SG-NFS-XP-1
4. You can verify if the export package is running with the cmviewcl command. The output
is similar to the following:
# cmviewcl
CLUSTER STATUS
cluster1 up
NODE STATUS STATE
thyme up running
NODE STATUS STATE
basil up running
