Error while running hostsetup when installing LSF

rtynd4 — Thu, 06 Nov 2025 14:04:44 GMT

Hi,

I installed Platform_Process_Manager (LSF). When I go to execute this command:

sudo /usr/share/lsfm8/10.1/install/hostsetup --top="/usr/share/lsfm8" --boot="y" --profile="y" --start="y"

I go this error:

Logging installation sequence in /usr/share/lsfm8/log/Install.log

------------------------------------------------------------

L S F H O S T S E T U P U T I L I T Y

------------------------------------------------------------

This script sets up local host (LSF server, client or dynamic host) environment.

[Wed Nov 5 15:38:23 EST 2025:hostsetup:ERROR_6012]

Host "xxx" is not defined in the cluster.

When setting the host name in the install.config I set these settings:

JS_HOST=xxx.yyy.zzz
LSF_MASTER_LIST="xxx.yyy.zzz"

No where did I set the host name to just the short name xxx.

Please advise how I might fix this issue.

The script runs the "hostname" command to acquire the local host name and strips the domain if present, so that's where the short name is coming from. The script is checking that hostname against the contents of the lsf.cluster file and not finding a match, causing the error.

You could modify the lsf.cluster file to use the short name to resolve the issue.

I see this file: "lsf.cluster.sas_cluster"

Is this the file you are referring to?

I tried adding the host name as just:

Begin Host
HOSTNAME model type server RESOURCES #Keywords
#apple Sparc5S SUNSOL 1 (sparc bsd) #Example
#peach DEC3100 DigitalUNIX 1 (alpha osf1)
#banana HP9K778 HPPA 1 (hp68k hpux)
#mango HP735 HPPA 1 (hpux cs)
#grape SGI4D35 SGI5 1 (irix)
#lemon PC200 LINUX 1 (linux)
#pear IBM350 IBMAIX4 1 (aix cs)
#plum PENT_100 NTX86 1 (nt)
#berry DEC3100 ! 1 (ultrix fs bsd mips dec)
#orange ! SUNSOL 1 (sparc bsd) #Example
#prune ! ! 1 (convex)
xxx.yyy.zzz ! ! 1 (mg)

xxx ! ! 1 (mg)
End Host

But that did not help.

Could I temporarily change the host name to the short name?

Thanks for the help.

I did change the lsf.cluster.sas_cluster to use just the short name but got the same error.

After editing lsf.cluster.sas_cluster did you run lsadmin reconfig and badmin reconfig? I believe these are required to recognize the new name defined.

Well :),

I just installed this yesterday and this is my first install.

The processes are not running so of course I get this error:

xxx:/usr/share/lsfm8/conf> badmin reconfig

Checking configuration files ...

There are fatal errors.

The server has not been rebooted yet. I may have that done and then try to get the processes running.

What's in this file?
/usr/share/lsfm8/log/Install.log

Re: Error while running hostsetup when installing LSF

MrSantos — Thu, 06 Nov 2025 16:51:00 GMT

If you're installing the first node (or a single one) you probably don't need hostsetup. This link mentions hostsetup as optional following an install: lsfinstall - IBM Documentation

You can find more information on LSF installation here: Install or upgrade IBM Spectrum LSF - IBM Documentation

Not much, just the same output after running the hostsetup command.

Some of the files do not have the setuid set on them.

will this command set them?

sudo /usr/share/lsfm8/10.1/install/hostsetup --top="/usr/share/lsfm8" --setuid

what is top normally set to?

Do I run this for /usr/local/pm too?

Re: Error while running hostsetup when installing LSF

You could add "set -x" to the top of the hostsetup file under "#!/bin/sh", which would write out all the actions the script is performing.

From what I can tell, error 6012 is thrown when the value of $LOCAL_HOST is not in the list of servers and clients it reads from lsf.cluster.cluster-name, if it can find it. If it can't find it, it does check also the LSF configuration directory's hosts file for aliases, if the file exists (e.g. /usr/share/lsfm8/conf/hosts.
So if you changed the lsf.cluster.cluster-name file such that XXX is present there that would make me think that the script is failing to read it at all, or is reading a different file.

I was never able to run badmin reconfig because I cannot get lim to start. I run lsfstartup and it runs a long time. I keep killing it. No log files are created. I am going to let it run with the hope it will finally complete and create a lim.log file.

I had to compare the files with an existing installation to determine which files needed the setuid bit set and had the sysadmin manually set them. I did see in the hostsetup script what files to have that set.

I hardcoded the hostsetup LOCAL_HOST to the fqdn but I still get the same error about the host name not defined in the cluster.

Fyi, I am installing this on the same server as an older LSF install exists. I use a different admin account and different paths for the files.

Thx

I do see when I run lsfstartup this error but it does not exit:

scc8111:/usr/share/lsfm8/conf> sudo -E /usr/share/lsfm8/10.1/sparc-sol10-64/bin/lsfstartup

Do you really want to start up LIM on all hosts ? [y/n]y

The LOCAL_HOST variable is set by the script, setting it beforehand wouldn't change the behavior.

Re: Error while running hostsetup when installing LSF

By default, lsfstartup uses the "rsh" command to run commands on other hosts. This error is saying that you don't have rsh installed for that to work.
You can change this command to ssh using the LSF_RSH option in lsf.conf.

I tried that but I get prompted for the root password which I do not have.

Re: Error while running hostsetup when installing LSF

The lsfstartup command remotely executes the startup commands on each defined server, so your options here would be to set up the lsf sudoers so a non-root account can start LSF services and run lsfstartup using the normal account where you know the password. You could also setup passwordless SSH between the hosts for that account so you are not prompted for a password.

Alternatively you could SSH to each host in your grid and run the individual startup commands as root (e.g. lsadmin limstartup && lsadmin resstartup && badmin hstartup).

rtynd4 — Fri, 07 Nov 2025 16:28:19 GMT

thx for the help.

If the lsfsudoers file is set up correctly would this allow the lsfadmin account to run any of the lsf commands? It looks like it does.

I have been having issues with running the lsfstartup. It was running for hours and not completing. I started up the daemons individually and they are all running. I have been asking the sysdamin to grant sudo privs for each command.

Do you have a sample lsfsudoers file with dummy data?

I was told that I could have two installations of LSF on the same server using different paths and different admin accounts. The other LSF daemons were running while I was running lsfstartup, so not sure if that conflicted, will test. I have changed all the ports that I am aware of.

Yes, the lsf.sudoers file allows the defined non-root users to run LSF commands.

The documentation I linked provides an example of the contents and details about the various options you can set there.

LSF_STARTUP_USERS and LSF_STARTUP_PATH are I think all you'd need to allow a non-root user to start LSF.

Running multiple instances of LSF should be fine if you've changed all the ports in lsf.conf and ego.conf.
