While troubleshooting an ESXi issue on a Cisco UCS C210 M2 server, I ran into several small annoying issues which ultimately had me reboot the CIMC via SSH and I thought it would be good to write a short post about it in case I needed to remind myself what commands I used and possibly point someone to this post if I get asked about this in the future.
If your Cisco UCS C Series server’s CIMC ever becomes inaccessible via the webpage GUI meaning you’re no longer able to get to this page to reboot the CIMC:
There is another way to reboot it and that is to SSH into the server. With that being said, in order to SSH into the server, it has to be turned on here:
Now assuming you have SSH enabled, you can use an SSH client such as PUTTY to SSH over, log in, and execute:
The session would look something like this:
login as: admin
sucs-c2xx# scope cimc
ucs-c2xx /cimc # reboot
This operation will reboot the CIMC.
You can also perform a lot of operations here so if you ever get locked out of the management webpage or perhaps the port is blocked, you can perform the operations via the SSH.
