Installing LSF-HPC With SLURM Into an Existing Standard LSF Cluster

LSF_RSH=ssh
Save and exit the file.
4. Optional: Configure any special XC-specific queues.
For HP XC V2.1, HP recommends that you use a JOB_STARTER script, configured for all queues
on a XC system. The default installation of LSF on XC provides queue configurations in the
/opt/hptc/lsf/etc/configdir/lsb.queues. file. The JOB_STARTER script and its
helper scripts are located in the /opt/hptc/lsf/bin/ file. Depending on how they are
configured for use, you might need to move the scripts to a shared location. If you move the
scripts, edit the job_starter.sh script, updating its definition of loc, which provides the
location of the helper scripts.
The JOB_STARTER script minimizes the impact when a is launched on a non-XC node and you
can configure it on all queues, but use good judgement in employing this script on your cluster.
5. Optional: Adjust the LSF environment files if necessary.
When you install a new or different version of LSF, it renames the old profile.lsf and
cshrc.lsf files before replacing them with the files from the most recent installation. Ensure
that these files are consistent with the XC default LSF environment files, as configured previously.
Configuring the XC LSF alias
Having completed the XC LSF installation, log out and log back into XC to establish the proper LSF
environment.
The next step is to configure the LSF alias on XC. An alias is used on XC to prevent hardwiring LSF to
any one node, so that the LSF node in XC can fail over to another node if the current node becomes
compromised (hung or crashed). XC provides infrastructure to monitor the LSF node and fail over the
LSF daemons to another node if necessary.
The selected IP and host name must not be in use but must be known on the external network. The
example is using 'xclsf' with an IP address of '16.32.2.140', and the head node for the XC cluster is
'xc-head'.
To verify that the selected external host name is not currently in use, ping it as follows:
[root@xc128 conf]# ping xclsf
PING xclsf.lab.mycorp.com (16.32.2.140) 56(84) bytes of data.
From xc128.lab.mycorp.com (16.32.2.128) icmp_seq=0 Destination Host
Unreachable
Configure controllsf (which manages LSF setup on XC) with the new alias, as follows:
[root@xc128 root]# controllsf set virtual hostname xclsf
Confirm that the alias is set, as follows:
[root@xc128 root]# controllsf show
LSF is currently shut down, and assigned to node .
Failover is disabled.
Head node is preferred.
The primary LSF host node is xc128.
SLURM affinity is enabled.
The virtual hostname is "xclsf".
Starting LSF on XC
To update LSF with the latest configuration changes use the lsadmin reconfig and badmin
reconfig commands within the existing LSF cluster (on node plain in the example). Subsequent
