SnapCenter Linux plug-in installation fails to start SPL on RHEL 8.4 and higher

Last Updated:

Applies to

  • SnapCenter Plug-in for Oracle (SCO) on Linux 4.5
  • SnapCenter Plug-in for SAP HANA (SCHANA) on Linux
  • SnapCenter Plug-in for Creator (SCC) on Linux
  • RedHat Enterprise Linux (RHEL) 8.4


After the installation of the plug-in on Linux runs through without any errors, the post-installation check, accessing the SPL to check, fails with:
ERROR SnapManagerWeb_<JOB> PID=[3772] TID=[225] WebException caught while invoking https://<RHEL-HOST-FQDN>:8145...DiscoverPlugin
ERROR SnapManagerWeb_<JOB> PID=[3772] TID=[225] WebException Encountered, Response null
ERROR SnapManagerWeb_<JOB> PID=[3772] TID=[225] Exception in method: InvokeXML.

INFO  SnapManagerWeb_<JOB> PID=[3772] TID=[225] Enter RemoveHostTogMSAMapping
DEBUG SnapManagerWeb_<JOB> PID=[3772] TID=[225] No gMSA mapping exists for host : <RHEL-HOST-FQDN>
INFO  SnapManagerWeb_<JOB> PID=[3772] TID=[225] Exit RemoveHostTogMSAMapping
INFO  SnapManagerWeb_<JOB> PID=[3772] TID=[225] Exit plug-in discover on host refresh.
Note: this happens also when no Plug-in has been installed yet, so the first instance of this error in the log, before uploading and running the installer, is normal!
