HP XC System Software Installation Guide Version 3.1

Before you install the Maui Scheduler on an HP XC system, you must be sure that the HP XC version of
LSF-HPC with SLURM is not activated on the system. If LSF-HPC with SLURM is activated, you must
deactivate it before proceeding.
The following procedure describes how to determine if LSF-HPC with SLURM is activated and running
on the system and how to deactivate it. Deactivating LSF consists of first stopping the LSF service and
then disabling it.
1. From the head node, determine if LSF is installed on the system:
# which lsid
This command fails if LSF is not installed.
2. If the lsid binary is found, ensure that LSF is not running:
# lsid
• If the LSF service is running, perform step 3 to stop the service, then step 4 to disable LSF on the
system.
• If the LSF service is not running, perform step 4 to disable LSF on the system.
3. Stop the LSF service:
# pdsh -a /sbin/service lsf stop
4. Disable LSF:
# pdsh -a /sbin/chkconfig lsf off
Ensure That SLURM Is Installed and Running on the System
SLURM must be installed and running on the system before you install the Maui Scheduler.
Enter the following command to verify that SLURM is running on the system:
# pdsh -a service slurm status
n15: slurmd (pid 2682) is running...
n14: slurmd (pid 2372) is running...
n16: slurmctld (pid 3111) is running...
n16: slurmd (pid 3120) is running...

The Maui Scheduler Administrator’s Guide has a section called “Building and Installing Maui” which is very
useful. You can find this guide at:
