Environment

VMware Cloud Foundation 3.5.x

Resolution

This is a known issue affecting VMware Cloud Foundation 3.5.x. There is currently no resolution.

Workaround:
To workaround this issue, use the following procedure to manually import the Redfish SSL certificate into the SDDC Manager trusted keystore.
  1. SSH to the SDDC Manager VM as the vcf user and then issue the su - command to switch to the root user.
  2. Issue a command similar to the following to obtain the SSL certificate from the Redfish connector:
openssl s_client -servername [redfish IP] -connect [Redfish IP]:5000 </dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'>/tmp/redfish.crt

Notes:

  • Replace [Redfish IP] with the IP of the Redfish connector.
  • If the Redfish port has been changed from the default of 5000, the port value in the previous command needs to be updated accordingly.
  1. Issue the following command to import the certificate to the truststore:
keytool -import -alias [Redfish IP] -keystore /usr/java/jre-vmware/lib/security/cacerts -file /tmp/redfish.crt

Note: Replace [Redfish IP] with the IP of the Redfish connector.
  1. Issue the following command to restart the operationsmanager service:
systemctl restart operationsmanager


Note: If there is an existing Redfish connector certificate that needs to be deleted or replaced from the SDDC Manager truststore, run a command similar to the following to delete the certificate, and follow Steps 2 through 4 to import the new certificate.

keytool -delete -keystore /usr/java/jre-vmware/lib/security/cacerts -alias [Redfish IP]

Note: Replace [Redfish IP] with the IP of the Redfish connector.
