Spectrum LSF 10.1 Installation and Applying Patch | FP | interim FIX on Linux Platform

IBM Spectrum LSF (LSF, originally Platform Load Sharing Facility) is a workload management platform, job scheduler, for distributed high performance computing (HPC) by IBM. In January, 2012, Platform Computing was acquired by IBM. The product is now called IBM® Spectrum LSF.

IBM® Spectrum LSF is a complete workload management solution for demanding HPC environments that takes your job requirements, finds the best resources to run the job, and monitors its progress. Jobs always run according to host load and site policies.

LSF cluster (source)

  • Cluster is a  group of computers (hosts) running LSF that work together as a single unit, combining computing power, workload, and resources. A cluster provides a single-system image for a network of computing resources. Hosts can be grouped into a cluster in a number of ways. A cluster can contain 1) All the hosts in a single administrative group  2) All the hosts on a subnetwork.
  • Job is a unit of work that is running in the LSF system or  job is a command or set of commands  submitted to LSF for execution. LSF schedules, controls, and tracks the job according to configured policies.
  • Queue is a cluster-wide container for jobs. All jobs wait in queues until they are scheduled and dispatched to hosts.
  • Resources are the objects in your cluster that are available to run work. 

Spectrum LSF 10.1 base Installation  and applying FP /PTF/FIX

Plan your installation and install a new production IBM Spectrum LSF cluster on UNIX or Linux hosts. The following diagram illustrates an example directory structure after the LSF installation is complete.


Plan your installation to determine the required parameters for the install.config file.

a )  lsf10.1_lsfinstall.tar.Z

The standard installer package. Use this package in a heterogeneous cluster with a mix of systems other than x86-64. Requires approximately 1 GB free space.

b)  lsf10.1_lsfinstall_linux_x86_64.tar.Z 


Use this smaller installer package in a homogeneous x86-64 or ppc cluster accordingly . 


Get the LSF distribution packages for all host types you need and put them in the same directory as the extracted LSF installer script. Copy that package to LSF_TARDIR path mentioned in Step 3.

For example:

Linux 2.6 kernel glibc version 2.3, the distribution package is lsf10.1_linux2.6-glibc2.3-x86_64.tar.Z.

Linux  kernel glibc version 3.x, the distribution package is lsf10.1_lnx310-lib217-ppc64le.tar.Z


LSF uses entitlement files to determine which feature set is enabled or disabled based on the edition of the product. Copy  entitlement configuration file to LSF_ENTITLEMENT_FILE  path mentioned in step 3.

The following LSF entitlement configuration files are available for each edition:

LSF Standard Edition  ===>  lsf_std_entitlement.dat

LSF Express Edition   ===>  lsf_exp_entitlement.dat

LSF Advanced Edition  ==>  lsf_adv_entitlement.dat


Step 1 : Get the LSF installer script package that you selected and extract it.

# zcat lsf10.1_lsfinstall_linux_x86_64.tar.Z | tar xvf -

Step 2 :  Go to extracted directory :

 cd lsf10.1_lsfinstall

Step 3 : Configure install.config as per the plan

 cat install.config
  LSF_ADD_SERVERS="myhost1 myhost2 myhost3 myhost4 myhost5 myhost6 myhost7 myhost8"


Step 4:  Start LSF 10.1 base installation 

          ./lsfinstall -f install.config

After installation, remember to bring your cluster up to date by applying the latest updates and bug fixes.

NOTE: You can do LSF installation as  non-root user. That will  be similar but with one extra prompt for multi-node cluster(yes/no)

Step 5 :  This step required only if installation was done by root .

 chown -R lsfadmin:lsfadmin $LSF_TOP

Step 6 :  check the binary files 

cd LSF_TOP/10.1/linux3.10-glibc2.17-x86_64/bin

Step 7 : By default, only root can start the LSF daemons. Any user can submit jobs to your cluster. To make the cluster available to other users, you must manually change the ownership and setuid bit for the lsadmin and badmin binary files to root, and the file permission mode to -rwsr-xr-x (4755) so that the user ID bit for the owner is setuid.

 chown root lsadmin
 chown root badmin
 chmod 4755 lsadmin
 chmod 4755 badmin
 ls -alsrt lsadmin
 ls -alsrt badmin

chown root  $LSF_SERVERDIR/eauth  

chmod u+s $LSF_SERVERDIR/eauth 

Step 8 : Configure  /etc/lsf.sudoers 

[root@myhost1]# cat /etc/lsf.sudoers

NOTE: This lsf.sudoers file is not installed by default. This file is located in /etc. lsf.sudoers file is used to set the parameter LSF_EAUTH_KEY to configure a key for eauth to encrypt and decrypt user authentication data. All the nodes/hosts should have this file . Customers need to configure LSF_EAUTH_KEY in /etc/lsf.sudoers on each side of multi-cluster. 

Step 9 : check $LSF_SERVERDIR/eauth   and copy  lsf.sudoers to all hosts in the cluster

 ls  $LSFTOP/10.1/linux3.10-glibc2.17-x86_64/etc/

scp /etc/lsf.sudoers myhost02:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost03:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost04:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost05:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost06:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost07:/etc/lsf.sudoers
scp /etc/lsf.sudoers myhost08:/etc/lsf.sudoers

Step 10 : Start LSF  as lsfadmin and check base Installation using  lsid command.

Step 11 : Check binary type with  lsid -V

binary type: linux3.10-glibc2.17-x86_64

NOTE:  Download required FP and interim fixes from 

Step 12 : Before applying PTF12 and interim patches , bring down the LSF daemons.  Use the following commands to shut down the original LSF daemons

 badmin hshutdown all
 lsadmin resshutdown all
 lsadmin limshutdown all

Deactivate all queues to make sure that no new jobs can be dispatched during the upgrade:

badmin qinact all 

Step 13: Then, become the root to apply FP12 and interim patches . 

Set LSF environment :   .   LSF_TOP/conf/profile.lsf

.   /nfs_shared_dir/LSF_HOME/conf/profile.lsf

Step 14: Apply  FP 12 on LSF BASE installation.  The patchinstall is available in $LSF_TOP//install directory

         # cd $LSF_TOP/10.1/install

Perform a check on patches running. It is recommended to check for the patch before its installation

ClusterName      Servers
CLUSTER1       (cloudhost)
CLUSTER2       (myhost1)
CLUSTER3       (remotehost2)

          End Cluster

Step 19 : Switch back to  user lsfadmin. Use the following commands to start LSF using the newer daemons.

  lsadmin limstartup all
lsadmin resstartup all
badmin hstartup all

Use the following command to reactivate all LSF queues after upgrading: badmin qact all

Step 20 : Modify Conf files as per requirement add queues, clusters...etc . Then run badmin reconfig or lsadmin reconfig as explained in LSF configuration section below.  Restart LSF as "lsfadmin" user .

Spectrum LSF Cluster Installation and FP12 upgradation completed successfully  as per the details copied above.

You must run hostsetup as root to use --boot="y" option to modify the system scripts to automatically start and stop LSF daemons at system startup or shutdown. . The default is --boot="n".

1. Log on to each LSF server host as root. Start with the LSF master host.

2. Run hostsetup on each LSF server host. For example:

# cd $LSF_TOP/10.1/install

# ./hostsetup --top="$LSF_TOP" --boot="y"

NOTE: For more details on hostsetup usage, enter hostsetup -h.

In case of multi-cluster environment, reinstalling  master cluster would show status=disk  after issuing bclusters command. 

[smpici@c656f7n06 ~]$ bclusters
[Job Forwarding Information ]

            Queue1              send                     CLUSTER1          disc
            Queue2              send                     CLUSTER2          disc
            Queue3              send                     CLUSTER3          disc

where status=disc means communication between the two clusters is not established. The disc status might occur because no jobs are waiting to be dispatched, or because the remote master cannot be located.

Possible solution is to cleanup all the LSF daemons on all clusters. Note : lsfshutdown leaves some of the daemons on Master node. So , you need to manually kill all the LSF daemons on all master nodes.

Later,  bclusters should show the status as shown below:

[smpici@c656f7n06 ~]$ bclusters
[Job Forwarding Information ]

Queue1                              send        CLUSTER1                     ok
Queue2                              send        CLUSTER2                     ok
Queue3                              send        CLUSTER3                     ok


======================= LSF configuration section ===========================

After you change any configuration file, use the lsadmin reconfig and badmin reconfig commands to reconfigure your cluster. Log on to the host as root or the LSF administrator (in our case "lsfadmin")

Run lsadmin reconfig to restart LIM and checks for configuration errors. If no errors are found, you are prompted to either restart the lim daemon on management host candidates only, or to confirm that you want to restart the lim daemon on all hosts. If unrecoverable errors are found, reconfiguration is canceled. Run the badmin reconfig command to reconfigure the mbatchd daemon and checks for configuration errors.

  • lsadmin reconfig to reconfigure the lim daemon
  • badmin reconfig to reconfigure the mbatchd daemon without restarting
  • badmin mbdrestart to restart the mbatchd daemon
  • bctrld restart sbd to restart the sbatchd daemon

Spectrum scale :High-performance storage GPFS cluster Installation and setup

IBM Spectrum Scale(formerly GPFS) is a scale-out high performance global parallel file system (cluster file system) that provides concurrent access to a single file system or set of file systems from multiple nodes. Enterprises and organizations are creating, analyzing and keeping more data than ever before. Islands of data are being created all over the organization and in the cloud creating complexity, difficult to manage systems and increasing costs. Those that can deliver insights faster while managing rapid infrastructure growth are the leaders in their industry. In delivering those insights, an organization’s underlying information architecture must support the hybrid cloud, big data and artificial intelligence (AI) workloads along with traditional applications while ensuring security, reliability, data efficiency and high performance. IBM Spectrum Scale™ meets these challenges as a parallel high-performance solution with global file and object data access for managing data at scale with the distinctive ability to perform archive and analytics in place.

Manually installing the IBM Spectrum Scale software packages on POWER nodes myhost1, myhost2 and myhost3

The following packages are required for IBM Spectrum Scale Standard Edition on Red Hat Enterprise Linux:

  1. gpfs.base*.rpm
  2. gpfs.gpl*.noarch.rpm
  3. gpfs.msg.en_US*.noarch.rpm
  4. gpfs.gskit*.rpm
  5. gpfs.license*.rpm

Step 1:Download spectrum scale SE package from fix central and Install RPM packages on all nodes:

 rpm -ivh gpfs.base*.rpm gpfs.gpl*rpm gpfs.license.std*.rpm gpfs.gskit*rpm gpfs.msg*rpm*rpm

Step 2 : Verify installed GPFS packages

 [root@myhost1 ]# rpm -qa | grep gpfs

Step 3 : Build GPL ( module by issuing command mmbuildgpl on all nodes in cluster.

Step 4 : Verify GPFS packages installed on all nodes with GPL module built properly.

              Export the path for GPFS commands. 

              export PATH=$PATH:/usr/lpp/mmfs/bin

Step 5 : Use the mmcrcluster command to create a GPFS cluster

mmcrcluster -N NodeFile -C smpi_gpfs_power8

                    where NodeFile has following entries

#cat NodeFile

Step 6: Use the mmchlicense command to designate licenses as needed. This command controls the type of GPFS license associated with the nodes in the cluster. -- accept indicates that you accept the applicable licensing terms. 

 mmchlicense server --accept -N serverLicense

Step 7: mmgetstate command. Displays the state of the GPFS™ daemon on one or more nodes.

 mmgetstate -a

Step 8: mmlslicense command displays information about the IBM Spectrum Scale node licensing designation or about disk and cluster capacity.

 mmlslicense -L

Step 9: The mmcrnsd command is used to create cluster-wide names for NSDs used by GPFS. This is the first GPFS step in preparing disks for use by a GPFS file system.

 mmcrnsd -F NSD_Stanza_smpi_gpfs_power -v no

 where NSD_Stanza_smpi_gpfs_power has

#cat NSD_Stanza_smpi_gpfs_power



Step 10: Use the mmlsnsd command to display the current information for the NSDs belonging to the GPFS cluster.

 mmlsnsd -X

Step 11: Use the mmcrfs command to create a GPFS file system

 mmcrfs smpi_gpfs -F NSD_Stanza_smpi_gpfs_power

Step 12: The mmmount command mounts the specified GPFS file system on one or more nodes in the cluster.

 mmmount smpi_gpfs -a

Step 13 : Use the mmlsfs command to list the attributes of a file system.

 mmlsfs all

Step 14: The mmlsmount command reports if a file system is in use at the time the command is issued.

 mmlsmount all

step 15: How to change the mount point from /gpfs to /my_gpfs 

 mmchfs gpfs -T /my_gpfs

Step 16:  GPFS auto start and auto mount  setup

This Quick Start automatically deploys a highly available IBM Spectrum Scale cluster on the Amazon Web Services (AWS) Cloud. This Quick Start deploys IBM Spectrum Scale into a virtual private cloud (VPC) that spans two Availability Zones in your AWS account. You can build a new VPC for IBM Spectrum Scale, or deploy the software into your existing VPC. The deployment and configuration tasks are automated by AWS CloudFormation templates that you can customize during launch.

IBM's container-native storage solution for OpenShift is designed for enterprise customers who need global hybrid cloud data access. These storage services meet the strict requirements for mission critical data. IBM Spectrum® Fusion provides a streamlined way for organizations to discover, secure, protect and manage data from the edge, to the core data center, to the public cloud.

Spectrum Fusion

IBM launched a containerized derivative of its Spectrum Scale parallel file system called Spectrum Fusion. The rationale is that customers need to store and analyze more data at edge sites, while operating in a hybrid and multi-cloud world that requires data availability across all these locations. The ESS arrays provide Edge storage capacity and a containerized Spectrum Fusion can run in any of the locations mentioned. It’s clear that to build, deploy and manage applications requires advanced capabilities that help provide rapid availability to data across the entire enterprise – from the edge to the data center to the cloud. 

Spectrum Fusion combines Spectrum Scale functionality with unspecified IBM data protection software. It will appear first in a hyperconverged infrastructure (HCI) system that integrates compute, storage and networking. This will be equipped with Red Hat Open Shift to support virtual machine and containerized workloads for cloud, edge and containerized data centres.

Spectrum Fusion will integrate with Red Hat Advanced Cluster Manager (ACM) for managing multiple Red Hat OpenShift clusters, and it will support tiering. Spectrum Fusion provides customers with a streamlined way to discover data from across the enterprise as it has a global index of the data it stores. It will manage a single copy of data only – i.e. there is no need to create duplicate data when moving application workloads across the enterprise. Spectrum Fusion will integrate with IBM’s Cloud Satellite, a managed distribution cloud that deploys and runs apps across the on-premises, edge and cloud environments.
