Hi Amit,

 

Its a bit hard to tell from the screenshots that you have enclosed which SpectroSERVERs are the Primary and which one are the Secondary.

However both SpectroSERVERs need to have the same landscape handle the same MAIN_LOCATION_HOST_NAME setting in the .locrc file.  So that the secondary SpectroSERVER server points to the same system name as the .locrc file on the primary SpectroSERVER.

Also the secondary SSdb needs to be manually copied over from the Primary and then loaded with a higher precedence value (normally 20 is used) from $SPECROOT/SS

../SS-Tools/SSdbload -il -add precedence savefile

 

Further details are available here

 

Establish Fault Tolerance - CA Spectrum - 10.1 and 10.1.1 - CA Technologies Documentation 

 

Also another common issue is to verify the ports are opened and connections are available between the SpectroSERVERs and the OneClick server.  Also we recommend to set a backup MLS server on the OneClick server in case the MLS server goes down.

 

Firewall settings are here

 

Primary and Secondary SpectroSERVER Communication Across Firewalls - CA Spectrum - 10.1 and 10.1.1 - CA Technologies Doc… 

 

Also I would strongly suggest to populate the OS etc/hosts files with all servers in your environment and case sensitivity does matter in Spectrum.

 

Please let me know if you have any additional questions regarding this.

 

Best regards,

Dear Glenn,

 

my primary server is switched to secondary server but our other landscape server is removed from one click console when our primary MLS is down.

Hi Amit,

  If you are still experiencing this problem please open a support case.  We would need to check the configuration of both machines. If you are going to open a case, please run the <SPECROOT>/bin/support/getSpectrumInfo.sh script with the "lite" option (run it from the <SPECROOT> directory) on both the primary and secondary servers and upload the resulting file.  

Thank you

Jay

Whether it is new set up? whether all the ports are opened .Check the firewall ports once.
