HP XC System Software Administration Guide Version 3.1

NodeName=n[1-5] Procs=2 RealMemory=1994
NodeName=n[6-8] Procs=2 RealMemory=4032
These lines change to:
NodeName=n[1-5] Procs=2 RealMemory=1994
NodeName=n[6-8] Procs=2 RealMemory=4032
NodeName=n9 Procs=2 RealMemory=2008
NOTE: If node the value for the RealMemory characteristic of n9 were 4032 in the example,
the portion of the file would be changed to the following:
NodeName=n[1-5] Procs=2 RealMemory=1994
NodeName=n[6-9] Procs=2 RealMemory=4032
The order of NodeNames arguments listed in this file is important because SLURM uses this to
determine the contiguity of the nodes.
b. Locate the line that begins with PartitionName=. Add the node name of the new node to the
list of nodes.
PartitionName=lsf RootOnly=YES Shared=FORCE Nodes=n[1-9]
c. Save the file and exit the editor.
6. Ensure that SLURM is running by issuing the following command:
# service slurm status
slurmd (pid PID) is running...
where PID is the process identifier.
If SLURM is not running, start it with the following command:
# service slurm start
7. Execute the following command to reconfigure SLURM:
# scontrol reconfigure
8. Verify the configuration with the following command:
# sinfo
PARTITION AVAIL TIMELIMIT NODES STATE NODELIST
lsf up infinite 9 idle n[1-9]
NOTE: If SLURM is not started on the new node, the sinfo command output shows it as down.
Restart SLURM in that instance.
14.10 Removing SLURM
The HP XC system installation process offers a choice of two different types of LSF. The default choice,
LSF-HPC with SLURM, requires that SLURM is installed and configured. The other choice is standard
LSF, which does not require nor interact with SLURM. If you choose standard LSF, SLURM is not configured.
If SLURM has been installed and configured but is not required, use the following procedures to deactivate
it:
