HP XC System Software Installation Guide Version 2.1

Review the Maui Documentation
Before installing and configurin g the Maui Scheduler on your XC s ystem , review the
information available at the following Web sites:
• http://www.chpc.utah.edu/docs/manuals/software/maui.html
• http://supercluster.org/research/papers/xlinux99.shtml
• http://www.clusterresources.com/products/maui/
Ensure That LSF HPC Is Not Activated
HP does not support the use of the Maui Scheduler with the HP XC version of LSF HPC. These
schedulers have not been integrated and will not work together on an HP XC system.
Before you install the Maui S cheduler on an HP XC system, you must be sure that the HP
XC version of LSF HPC is not activated on your system. If LSF HPC is activated, you must
deactivate it before proceeding.
The following procedure describes how to determine if LSF HPC is activated and running on
your system, and how to deactivate it. Deactivating LSF HPC consists of first stopping the LSF
service if it is running and then disabling it.
1. Determine if the LSF service is running on your system:
# controllsf status
This command will return either up (running) or down (not runn ing).
• If the LSF service is running, perform step 2 to stop the service, then step 3 to disable
LSF HPC on the system.
• If the LSF service is not running, perform step 3 to disable LSF HPC on the system.
2. Stop the L SF service by issuing the following comm a nd from the head node:
# service lsf stop
3. Disable LSF HPC by issuing the follow ing c om mand from the head node:
# chkconfig lsf off
Ensure That SLURM Is Installed and Running on the System
SLURM must be installed and running on th e system before you install the Mau i Scheduler.
SLURM is normally installe d and running by default.

# pdsh -a service slurm status
n15: slurmd (pid 2682) is running...
n14: slurmd (pid 2372) is running...
n16: slurmctld (pid 3111) is running...
