OME 2.1 updated the WS-MAN communication component. The newer component enforces better security policies and does not communicate with the devices if the certificates are expired.
You can update the expired certificates on the devices as follows:
For iDrac: Open command line console ( SSH or Telnet ) and execute below RACADM command , this will reset the certificate to future date and resolves the issue.
-> racadm sslresetcfg
You will see the following output for the command:
Reset iDRAC to apply new certificate. Until iDRAC is reset old certificate will be active.
-> racadm racreset
You will see the following output for the command:
RAC reset operation initiated successfully. It may take a few minutes for the RAC to come online again.
For CMC:
Open CMC command line console ( SSH or Telnet ) and execute below RACADM command , this will reset the certificate to future date and resolves the issue.
$ racadm sslresetcfg
You will see the following output for the command:
Certificate regenerated successfully and webserver will be restarted
