Symptoms

In some situations, it is necessary to manually import the SSL certificates in vCenter after VxRail initial deployment.

Cause

Replacing vCenter SSL self-signed certificate with a previously owned certificate.

Resolution

A Python script is attached to this article in a .zip file (check the bottom of the article) to provide the importing process. Run this script AS ROOT on VxRail Manager, and use --help to obtain usage. Remove the script after use. Note: The script works on VxRail 4.5.x, 4.7.x, 7.x, and 8.x. Script in this article was updated on May 23, 2025. Starting from 7.0.480, the script has been added into VxRail Manager at /mystic/ssl/cert_util.py. You can run this script directly. Follow these steps to replace certificates on VxRail Manager: Download the python script cert_util_pkb.zip and upload it to VxRail Manager.You must now use SSH log in to VxRail Manager and switch to ROOT user.Extract script cert_util_pkb.zip: # unzip cert_util_pkb.zip Run the script: # python cert_util.py Wait for the VxRail plug-in UI to load. It may take up to 10 minutes for the UI to be read. Example script output: vxm:/home/mystic # python cert_util.py Verify certificate against vCenter vcluster101-vcsa.vv003.local Downloaded root CA certificate zip to /tmp/tmpw2w8j7_r Downloaded root CA certificate zip from vcluster101-vcsa.vv003.local Found certificates ['certs/lin/53f38aa6.0', 'certs/lin/53f38aa6.r0'] that can verify server certificate Clean up existing certificates in /var/lib/vmware-marvin/trust/ - Removing /var/lib/vmware-marvin/trust/lin/53f38aa6.r0 - Removing /var/lib/vmware-marvin/trust/lin/53f38aa6.0 Clean up existing crl files in /var/lib/vmware-marvin/trust/crl/ Root CA certificate /tmp/certs/lin is saved at /var/lib/vmware-marvin/trust/.
