HP-UX High Availability Sample Questions:

1. DRAG DROP
Configure a Serviceguard package by dragging and dropping the appropriate options into the empty fields.
The package will be called 'missionspace' and will have an IP address of 15.20.30.10 on the 15.20.30.0 network. A failure of the 15.20.30.0 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/spacemon and passing it the argument "monitor".
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.

On this two node cluster, what happens if the heartbeat LAN on system_a fails?

A) The package ora_pkg will failover to node system_b.
B) On system_a the standby LAN card will be configured as heartbeat LAN card and the cluster status will not change.
C) Node system_a will TOC and node system_b will reform a one node cluster.
D) Both systems will try to grab the lock_disk and whoever activates the lock_vg first will reform the cluster and the other node will TOC.
