Reset CIMC server with API call

[smailmilak]

Hi,

I have a bunch of C220 servers connected to the FI's. The OS has to be reinstalled quite often on all of them but every time I have to reset CIMC server on every node manually, otherwise the installation fails.

How can I reset the CIMC server on all servers with one simple API call? Doing this manually is time consuming and frustrating.

UCSM SDK (https://github.com/CiscoUcs/ucsmsdk) has this ability.

Did a [Reset CIMC] for Server 4 in the lab and saw the request from UCSM Web GUI to UCSM was:

<configConfMos cookie="1592922190/45######-####-####-####-##########03" inHierarchical="false">
    <inConfigs>
<pair key="sys/rack-unit-4">
    <computeRackUnit
    adminPower="bmc-reset-immediate"
    id="4"
    dn="sys/rack-unit-4"
    
    status="created,modified"
    
    sacl="addchild,del,mod">
    </computeRackUnit>
</pair>
    </inConfigs>
</configConfMos>

Searching UCSM SDK for adminPower shows the source:

https://github.com/CiscoUcs/ucsmsdk/blob/7d721263a67811ad1f8a1576ad22249663eab88e/ucsmsdk/mometa/compute/ComputeRackUnit.py

You'll need a loop to gather all server IDs (eg sys/rack-unit-4 for the above test) then update that MO (managed object) and set adminPower accordingly.

Thanks a lot Steven.

I'm not experienced with API calls but I will give my best.

Greetings.

If you have standalone servers , you can also try:

curl -XPOST -k -u admin:YOURCIMCPASSWORD https://x.x.x.x/redfish/v1/Managers/CIMC/Actions/Manager.Reset -d '{"ResetType":"ForceRestart"}'

or

curl -XPOST -m 5 -k -u admin:YOURCIMCPASSWORD https://x.x.x.x/redfish/v1/Managers/CIMC/Actions/Manager.Reset -d '{"ResetType":"ForceRestart"}'

The -m 5 parameter is max time (5 seconds in our case) curl waits.  You might get an error like :

curl: (28) Operation timed out after 5001 milliseconds with 0 bytes received

But the reset command is still completed.

Know this doesn't work with UCSM integration, but thought I'd add this here for others looking for similar requests for standalone.
