HP XC System Software Installation Guide Version 4.0

Verifying HP Serviceguard
Enter the following commands to verify the installation and configuration of Serviceguard:
1. List the nodes that are members of availability sets:
# shownode config hostgroups
hostgroups:
headnode: n16
serviceguard:avail1: n14
n16
In this example, one availability set, avail1, has been configured.
2. On one node in each availability set, view the status of the Serviceguard cluster:
# pdsh -w n14 /usr/local/cmcluster/bin/cmviewcl
NOTE: The /usr/local/cmcluster/bin directory is the default location of the
cmviewcl command. If you installed Serviceguard in a location other than the default, look
in the /etc/cmcluster.conf file for the location of the Serviceguard bin directory.
Successful command output is similar to the following:
CLUSTER STATUS
avail1 up
NODE STATUS STATE
n14 up running
PACKAGE STATUS STATE AUTO_RUN NODE
sim.n14 up running enabled n14
kdump.n14 up running enabled n14
nat.n14 up running enabled n14
lvs.n14 up running enabled n14
nagios.n14 up running enabled n14
dbserver.n14 up running enabled n14
hptc_cluster_fs.n14 up running enabled n14
NODE STATUS STATE
n16 up running
PACKAGE STATUS STATE AUTO_RUN NODE
nat.n16 up running enabled n16
8.3 Running the OVP to Verify Software and Hardware Components
The operation verification program (OVP) verifies the major HP XC software and hardware
components to provide a level of confidence that the system has been installed and configured
correctly.
The OVP performs various tests to verify the following:
• The interconnect is functional.
• Network connectivity has been established.
• The administration network is operational.
• A valid license key file is installed and the license manager servers are up.
• All compute nodes are responding and are available to run applications.
• SLURM control daemons are responding and partitioning is valid if LSF with SLURM is
configured.
• LSF is up and running, if LSF is configured.
• An MPI job can be compiled, launched, and executed (through the xring test)
• Serial and parallel applications can be submitted and executed through LSF from all compute
nodes, if LSF is configured.
• CPU usage on all nodes except the head node (by default).
