Hi Mohit

Thank you for the question, please would you provide some more details on the version of Commvault and MongoDB you are using and any error messages being seen?

Thanks,

Stuart

Hey Mohit,

Can you confirm what SSL options you have enabled in the mongod configuration file? Depending on what’s enabled will depend on what options you will need to configure as per the documentation link you have referenced.

When using the mongo client to connect, what parameters are you needing to pass to it?

If possible you can paste your mongod configuration file - removing/scrubbing any sensitive information of course.

CS, Client, and Media agent version - 11.20.32

MongoDB 

CS, Client, and Media agent version - 11.20.32

MongoDB Version - v4.0.19

Configuration -

PEMKeyFile: /u01/app/mongodb/admin/27052/ssl/PEMKeyfile.pem

CAFile: /u01/app/mongodb/admin/27052/ssl/CAFile.pem

PemKeyPassword : None( leave this empty)

Hey Rohit,

Sorry for the delay here - I’m not sure if you’re using the all the correct additinal settings . Can you confirm how you’re logging in with the mongo client? What parameters are used? Also - please confirm all SSL related settings in the monod config file.

Thank you . I raised a case with support and they helped me with the resolution of this issue.

Hosts has “cname” which is recognizable by database , when I updated the hostname in commcell to there cname , discovery works fine.

Hey Mogit,

That’s good to hear!

If you could mark this thread as answered that would be great.
