2.Click the Cluster Configuration Diagram button to answer this item.

Fill in the indicated disk device files on the Cluster Configuration Diagram using c?t?d? format.

Correct:
3.Click the Task button to begin. Configure a Serviceguard package by dragging and dropping the appropriate options into the empty field locations. There is more than one possible answer. The package will be called 'missionspace' and will have an IP address of 10.20.30.10 on the 10.20.30.0 network. A failure of the 10.20.30.0 network will cause the package to fail over to the adoptive node. The package will run on FIONA as the primary node and fail back from SHREK manually. A service process called space_monitor will be used to monitor the health of the package. The monitor is started by running the script /etc/cmcluster/EPCOT/spaceman and passing it the argument A failure of this process 2 times will cause the package to fail to the alternate node without affecting the node it is running on. The package mounts the logical volume /dev/vg04/moonvol at the directory /opt/moon. The filesystem type should be the Veritas file system and mounted with a delaylog option. The application is started by the command: /opt/moon/missionspace/takeoff.sh and stopped by the command: /opt/moon/missionspace/touchdown.sh.

The package has the following characteristics: The package will be called 'toystory' and will have an IP address of 15.31.54.64 on the 15.31.54.0 network. A failure of this network will NOT affect the package running on the node. The package will run on WOODY as the primary node and fail back from BUZZ manually. The package will mount the following veritas logical volumes with the delaylog option: /opt/vgtoys/lvo11 /opt/bin/toystory /opt/vgtoys/lvo12 /opt/bin/toystory/logs /opt/vg06/datavo1 /toydata A service process called 'andy_room_mon' will be used to monitor the health of the package. The service process will have no restarts. The starting, stopping, and monitoring is run by using the script /etc/cmcluster/TOYS/andy_room.
