Hi All.  While installing Spectrum Control 5.4.13 GUI installation,  it get stuck forever at a stage and remains at 0%.  IBM DB2 is installed successfully and can connect to db2 etc. Other validations related to DB2 works fine.  But SC didn't gets installed at all.  OS is Linux RHEL 9.  The filesystems /, /home and /tmp have quite sufficient space , so space issue is not there for sure.  

And, then it remains here for ever. No progress.  Only 0%. 

No folders or directories gets created at all -

Anyone has experience with the install.  Any pointers.  Installation manual has no such screenshots on the installation steps at all.
Thanks

Hi All.

1. Installation stuck forever with 0% progress. Lax*err*Logs shows /tmp low on space. Increased /tmp by 50G.
2. In next run installation stuck forever with 0% progress. Logs have java.lang.NullPointerException: errors. Found a KB with eerily similar error message, but that was for IBM TSM Sterling Client - https://www.ibm.com/support/pages/installation-fails-javalangnullpointerexception
So, accordingly cleared the left-over folders of previous install attempts.
3. In next run installation failed at 14% (not stuck but failed). Logs have some IPv6 errors. So, disabled IPv6 by commenting its entry in /etc/hosts. db2stop/start.
4. In next run installation failed at 15% while creating DB Repository. Logs showed Database connection fails with authentication error SQL1639N
Resolved it via - https://www.ibm.com/support/pages/database-connection-fails-authentication-error-sql1639n
5. In next run installation failed at 34%, and DB Repository and few other components successfully installed. Did a partial rollback. Error was - BUILD FAILED: Exception caught updating device server status with the data server. TPC Data Server was not started.
Followed this link - https://www.ibm.com/support/pages/apar/IT09402#:~:text=Temporary%20fix,to%20resume%20the%20failed%20upgrade. It basically asks to first Start the Data Server manually via script and then retry the upgrade.  Didn't work though.
6. In next run installation still gives the same error of data server, and fails exactly at 34%, and exactly same messages in the logs like above Point#5.
7. It's enough now, so thought about trying with one version lower - Spectrum Control 5.4.12. Prior to this again downloaded a fresh copy of 5.4.13 in another server, brought it back here and again tried. Still same error of Point#5 above. Linux version of 5.4.13 may not be good copy at IBM PAO site. And they have not provided any checksum value to validate after the download. So, not sure.
8. Finally, tried installing Spectrum Control 5.4.12, and it completed without a single error. Yaay, Wow.
Thanks

Hi, 

1. Are you installing spectrum control using root user ? If no, will suggest doing it via root user and source the db2profile before install.

2. Check the lax.out / lax.err file which are present in /tmp folder. These files will have traces about the installation progress/possible failure reasons.

I will suggest opening a support case if possible..

Hi Jaideep. Thanks. Yes, using root account and output redirected to MobaxTerm X11 Windows GUI. Db profile executed first as well as per manual. Thanks

Hi Jaideep.  Almost all of the lax-xxxxxxxx-err.out files created after multiple runs, show this at the end, and rest not errors at all :

Also, during the same timeline,  we see DB2 logs with some errors like:

Required steps:
There were some errors detected during DB2 installation. To collect the information files from the system, run the "db2support -install" command with the proper options before reporting the problem to IBM service. For information regarding the usage of the db2support tool, check the DB2 Information Center.
DB2 Setup log file finished at:  Tue Aug 12 05:10:55 PM 2025 -05

DB2 was already installed and validated, as it was one of the pre-requisites. So, it seems it installs it once again when installing SC.

Thanks

Hi Bacil,

Glad to hear that you were finally able to complete the installation. Really appreciate your strong troubleshooting skills :)

The checksum values for installation images are linked in the SC download page( Download Packages Section) for individual Versions:

5.4.13 Download Page: https://www.ibm.com/support/pages/node/7180309

Hi Jaideep.  Thanks again. And thanks for letting me know that there indeed exists the checksum values at site for these downloads.  Good to know.

And I've seen lots of contents from you on Spectrum Control at few places on Spectrum Control Migrations and stuff and other SAN Performance stuff using Spectrum Control etc. And then was not getting much ahead with Support as well, so I thought on spending lots of time on this stuff to troubleshoot.  And finally, 5.4.12 got installed successfully.

Best Regards...
