HP-UX High Availability - HP0-093 Exam Practice Test
A package along with its associated volume groups and data are being migrated from one Serviceguard cluster to another. The volume groups were exported from the old cluster and imported into the new one.
The following error is produced by cmcheckconf:
Error: Volume group /dev/vg70 currently belongs to another cluster.
It cannot be included in this one.
Error: Volume group /dev/vg75 currently belongs to another cluster.
It cannot be included in this one.
Maximum configured packages parameter is 30.
Configuring 7 package(s).
23 package(s) can be added to this cluster.
cmcheckconf : Unable to verify cluster file:
/etc/cmcluster/cmclconf.ascii.
Cross-device link.
What change is required to resolve this error?

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.

In a two node cluster, two identical servers (same CPU, memory, and I/O card configurations) are designed to host the application and database servers of a 3-tier application. Under normal operations the database is hosted on server A and the application server is hosted on server B,each server with load at 90% of capancity.
What is likely to occur in the event of a single server failure, after both applications have migrated to the surviving node?
