We have two PowerEdge M1000e. The remote RACADM is not working for one CMC. That CMC has been upgraded to the latest firmware(5.22). Other remote access methods, including web, telnet and ssh are all working.
I tried to disable then re-enable RACADM from web interface, but I still cannot use RACADM remotely.
The command used:
racadm5 -r ip_of_cmc -u root -p "mypassword" getsensorinfo
The error message:
ERROR: Unable to connect to RAC at specified IP address.
I would verify if the other CMC is matching on firmware, because one being 5.22 and the other one isn't can cause issues. Also check to see if TLS 1.1 or higher is being used, as its required and the new update may install a version before that.
Let me know what you see.

Thanks for the reply.
I am connect from a Linux box to both CMC, so firmware version mismatch shouldn't be the cause. And that CMC is using TLS 1.2. Anyway, I have a feeling this problem is unsolvable, so I add my public key to CMC and use ssh instead.
