[. . . ] Use the Cluster Configuration Tool as follows to configure this example NFS service: 1. Verify that the cluster daemons are running in the Cluster Status Tool; if not, choose Cluster => Start Local Cluster Daemons. Choose the Services tab and, if services have already been defined, select one and click New. In this example, assume a failover domain named clu3_domain was previously created using the Cluster Configuration Tool, consisting only of member clu3 with both Restricted failover to only these members and Ordered Failover unchecked. In this way, clu3 is designated as the preferred member for this service. Specify a value of 30 in the Check Interval field to specify that the status of the NFS daemons should be checked every 30 seconds. Consequently, there is no need to create or specify a value for User Script when configuring an NFS service. In the Cluster Configuration Tool, select the service you just created, and click Add Child. On the Add Device or IP Address dialog box, choose Add Service IP Address and click OK. In the Service IP Address field, enter 10. This example assumes a hostname of clunfseng is associated with this IP address, by which NFS clients mount the file system. Note that this IP address must be distinct from that of any cluster member. The default netmask address will be used, so accept the default of None. The default broadcast address will be used, so accept the default of None. Click OK to complete the service IP address configuration. On the Add Device or IP Address dialog box, choose Add Device and click OK. In the Device Special File field, enter /dev/sdb11 which refers to the partition on the shared storage RAID box on which the file system will be physically stored. In the Mount Point field, enter /mnt/users/engineering. In the Options field, enter rw, nosuid, sync. In the Cluster Configuration Tool, select the device you just created, and click Add Child. Enter /mnt/users/engineering/ferris in the NFS Export Directory Name field and click OK. Repeat this step twice, adding NFS export directories named /mnt/users/engineering/denham and /mnt/users/engineering/brown. [. . . ] If either network- or serial-attached power switches are employed in the cluster hardware configuration, install the cluster software and invoke the clufence command to test the power switches. Invoke the command on each cluster system to ensure that it can remotely power-cycle the other cluster members. If testing is successful, then the cluster can be started. The clufence command can accurately test a power switch. [. . . ]
