Data Domain: DD Management Center is not able to retrieve current data from the managed system.

Data Domain systems upgraded to DDOS 8.3.1.40 and DDOS 8.6.1.20 stop reporting to DDMC 8.5.0.0 or DDMC 8.6.0.0.

The DDMC managed-systems begin to report "not-transmitting" after the Data Domain systems are upgraded.

From sms.info on the DDMC -

The SOAP protocol was upgraded in DDOS, changing the buffering behavior on TLS/SSL records, resulting in file transfers dropping pre-maturely.  Older versions of DDMC no longer work with newer versions of DDOS due to the file transfers dropping.

• Upgrade the DDMC to the latest LTS version. At publishing, current LTS DDMC 8.6.1.20 corrected the issue for 8.6.1.20 and 8.3.1.40 clients.
• Deleting each managed-client from the DDMC, following by deleting the trust on the DD may be necessary.
• Re-adding the managed-client to the DDMC will restore the mutual trust. Below are the recommendations from engineering.
