"Waiting for CMC/OME Modular power allocation response to power on" Message after upgrade

Hello all,

Today I attempted an update for a PowerEdge M640 to reach BIOS version 2.15.1. After the update was pushed the device needed to restart, which is normal, but since then it hasn't been able to boot due to the error on Remote Console Screen:

"Waiting for CMC/OME Modular power allocation response to power on"

Device was working normally before the update. The same update image was used on other edges and they worked fine.

How should I proceed please?

Hello Ahmad-Fathy

 

We typically see that where there is not enough power to power up the blade.

Do know of any power supply issues?

Has any hardware been added?

 

 

Is this chassis a VRTX or M1000e?

Is the CMC(s) on the latest firmware?

 

If you have Dual CMC try fail over CMC and check status?

 

You can give these steps a try and let me know:

*Try a flea power drain: shut down M640, remove from chassis. Hold in power button on the blade for 30 seconds. Reinstall to chassis and power up.

*Try a physical re-seat the M640; check results

*Try a virtual re-seat the M640; check results

*Try reset the iDRAC on the M640; check results

 

Do you have any other blade in the chassis you could shut down to see if this one can POST up and complete the BIOS update?

Give a Flea Power drain and Hopefully the issue will be resolved, if not change the Slot location and see

if the issue is with slot or not.
