HP XC System Software Administration Guide Version 2.1

virtual IP is an internal IP on the HP XC Administr
ation network, and the virtual ho stname is
lsfhost.localdomain. The LSF-HPC Execution H
ost is configured to host the vIP, then
the LSF-HPC daemons are started on that node.
The Nagios infrastructure contains a module that monito rs the LSF-HPC virtual IP. If it detects a
problem with the virtual I P (for example, the inabi lit y to ping it), the m onitoring code assum es
the node is down and chooses a new LSF-HPC Execution Ho st from the backup candidate
nodes on wh ich to set up the virtual IP and restart LSF-HPC.
12.2 Installation of LSF-HPC on SLURM
LSF-HPC for SLURM is installed by defaul
tduringcluster_config execution. This
installation is sufficient i f you inte
nd to keep the LSF cluster confined to the HP XC system
nodes. T his LSF installation can al
so be configured with another LSF cluster by purchasing
Platform’s MultiCluster license a
nd performing the appropr iate Mu ltiCluster config uration. See
Section 12.12 for information on c
onfiguring an exter nall y visibl e L SF - HP C vi rtu al hostname
for com munication on the externa
lnetwork
The LSF-HPC for SLURM tar files to be installed are located in the
/opt/hptc/lsf/files director y. Before the installation begins you are prompted for
the follow ing information:
• Primary LSF Administrator.
This user account is necessary
for establishing ownership of the LSF configuration file. If
the lsfadmin user account doe
s not exist, it will be created locally within HP XC. O ther
LSF a dm inistrators can be con
figured after the installation has comple ted. See the manual
titled Administerin g P latf
orm LSF from Pl atform Co mputing for more details.
• The name of the LSF cluster.
This nam e must be unique and unrelated to any network hostname. It is most useful in this
instance in identifying thi s HP X C system in a multicluster configuration.
The default name is hptclsf
.
After these values are obtained and verified, the LSF-HPC for SLURM installation runs
installing the appropriate files under /opt/hptc/lsf/top/. On completion, the following
post-installation procedures are performed:
• LSF-HPC directories are relocated to take ad vantage of the HP XC file system hierarchy.
The location of the LSF-H
PC inst allat ion is /opt/hptc/lsf/top, which contains
four directories:
conf
The conf directory is m oved to /hptc_cluster/lsf/conf;itis
linked through a soft link to /opt/hptc/lsf/top/conf.
work
The work directory is m oved to /hptc_cluster/lsf/work;itis
linked through a soft link to /opt/hptc/lsf/top/work.
log
The log directory is moved to /var/lsf/log; it is linked through a soft
link to /opt/hptc/lsf/top/log.
This ensures that all LSF logging remains local to the node cu rrently ru nning
LSF-HPC.
6.0
This directory remains in place and is imaged to each node of the HP XC
system.
• The SLURM resource is added to the configured LSF execution host
