5. Click Scripts > Load Script.

6. (Conditional) If this is an NSS volume or a shared pool, use a load script similar to the following example, depending on the configuration of your cluster and nodes:

   #!/bin/bash 
   . /opt/novell/ncs/lib/ncsfuncs
   
   # mount filesystem
   exit_on_error ncpcon mount /opt="noatime,nodiratime" volume_name=volume_ID
   
   # add IP address
   exit_on_error add_secondary_ipaddress messenger_partition_ip_address
   
   # start service
   exit_on_error /etc/init.d/novell-nmma start
   exit_on_error /etc/init.d/novell-nmaa start
   
   # return status
   exit 0
   

   1. In the mount filesystem section, specify the volume name and volume ID of the Messenger partition that you are clustering (System Clustering Worksheet item 5).

   2. In the add ip address section, specify the secondary IP address of the Messenger partition (Messenger Clustering Worksheet item 6 or Messenger Clustering Worksheet item 7).

   3. In the start service section, provide the commands to start the Messaging Agent first, following by the Archive Agent.

7. (Conditional) If this is a traditional Linux volume, use an unload script similar to the following example, depending on the configuration of your cluster and nodes:

   #! /bin/bash
   . /opt/novell/ncs/lib/ncsfunc
   
   # define IP address
   RESOURCE_IP=messenger_partition_ip_address
   
   # define filesystem type
   MOUNT_FS=filesystem
   
   # define device (if using EVMS)
   exit_on_error evms -f /var/opt/novell/ncs/ContainerActivate -rl
                                                    Share ‘uname -n‘
   MOUNT_DEV=/dev/evms/Share/dat
   
   # define mount point
   MOUNT_POINT=/mnt/mount_point_directory
   
   # mount file system
   exit_on_error mount -t $MOUNT_FS $MOUNT_DEV $MOUNT_POINT -o noatime,nodiratime
   
   # add IP address
   exit_on_error add_secondary_ipaddress $RESOURCE_IP
   
   # start service
   exit_on_error /etc/init.d/novell-nmma start
   exit_on_error /etc/init.d/novell-nmaa start
   
   exit 0
   

   1. In the define IP address section, specify the secondary IP address of the Messenger partition (Messenger Clustering Worksheet item 6 or Messenger Clustering Worksheet item 7)

   2. In the define filesystem type section, specify the filesystem type that is in use on nodes in the cluster (System Clustering Worksheet item 5).

   3. In the define mount point section, specify the mount point directory in use for the nodes in the cluster (System Clustering Worksheet item 5).

8. Click Apply to save the load script.

1. On the iManager Cluster Resource Properties page of the Monitor Agent cluster resource, click Scripts > Unload Script.

2. (Conditional) If this is an NSS volume or a shared pool, use an unload script similar to the following example, depending on the configuration of your cluster and nodes:

   #!/bin/bash
   . /opt/novell/ncs/lib/ncsfuncs
   
   # request service stop
   ignore_error /etc/init.d/novell-nmma stop
   ignore_error /etc/init.d/novell-nmaa stop
   
   # stop service otherwise
   sleep 8
   ignore_error pkill -fx "'/etc/init.d/novell-nmma stop'"
   ignore_error pkill -fx "'/etc/init.d/novell-nmaa stop'"
   
   # delete IP address
   ignore_error del_secondary_ipaddress messenger_partition_ip_address
   
   # unmount filesystem
   exit_on_error umount /mnt/mount_point_directory
   
   # return status
   exit 0
   

   1. In the stop service otherwise section, adjust the sleep command as needed so that the Messenger agents can shut down normally on your system without being inadvertently killed by the pkill command that follows.

   2. In the delete IP address section, specify the secondary IP address of the Messenger partition.

   3. In the unmount filesystem section, specify the mount point directory in use for the nodes in the cluster.

   4. (Conditional) If you are running the GroupWise High Availability service (gwha), stop it before the script stops the Messenger agents, then start it again at the end of the unload script.

      This prevents the GroupWise High Availability service from trying to restart the Messenger agents while the script is trying to stop them.

      Add the following section before the request service stop section:

      # Temporarily disable the gwha service under xinetd
      ignore_error /sbin/chkconfig -s gwha off
      ignore_error kill -HUP `pidof xinetd`
      

      Add the following section before the return status section:

      # Restart the gwha service under xinetd
      ignore_error /sbin/chkconfig -s gwha on
      ignore_error kill -HUP `pidof xinetd`
      

3. (Conditional) If this is a traditional Linux volume, use an unload script similar to the following example, depending on the configuration of your cluster and nodes:

   #!/bin/bash
   . /opt/novell/ncs/lib/ncsfuncs
   
   # request service stop
   ignore_error /etc/init.d/novell-nmma stop
   ignore_error /etc/init.d/novell-nmaa stop
   
   # stop service otherwise
   sleep 8
   ignore_error pkill -fx "'/etc/init.d/novell-nmma stop'"
   ignore_error pkill -fx "'/etc/init.d/novell-nmaa stop'"
   
   # define IP address
   RESOURCE_IP=messenger_partition_ip_address
   
   # define mount point
   MOUNT_POINT=/mnt/mount_point_directory
   
   # delete IP address
   ignore_error del_secondary_ipaddress $RESOURCE_IP
   
   # umount filesystem
   exit_on_error umount $MOUNT_POINT
   
   # return status
   exit 0
   

   1. In the stop service otherwise section, adjust the sleep command as needed so that the Messenger agents can shut down normally on your system without being inadvertently killed by the pkill command that follows.

   2. In the define IP address section, specify the secondary IP address of the Messenger partition.

   3. In the define mount point section, specify the mount point directory in use for the nodes in the cluster.

   4. (Conditional) If you are running the GroupWise High Availability service (gwha), stop it before the script stops the Messenger agents, then start it again at the end of the unload script.

      This prevents the GroupWise High Availability service from trying to restart the Messenger agents while the script is trying to stop them.

      Add the following section before the request service stop section:

      # Temporarily disable the gwha service under xinetd
      ignore_error /sbin/chkconfig -s gwha off
      ignore_error kill -HUP `pidof xinetd`
      

      Add the following section before the return status section:

      # Restart the gwha service under xinetd
      ignore_error /sbin/chkconfig -s gwha on
      ignore_error kill -HUP `pidof xinetd`
      

4. Click Apply to save the unload script.

1. On the iManager Cluster Resource Properties page of the Messenger cluster resource, click General.

   The default policy settings are often appropriate. By default, a cluster resource:

   • Fails over automatically if the node it is running on fails

   • Starts automatically on the next node in its failover list

   • Continues running at its failover location, even after its most preferred node is again available

     If you are considering changing these defaults, see the Novell Cluster Services Administration Guide for Linux for your version of OES Linux.

2. Under Preferred Nodes, arrange the nodes in the cluster into the desired failover list for the Messenger agents (under Messenger Clustering Worksheet item 3).

3. Click OK.
