No CIMC and Continuous beeping sound on UCS C220

[jbeaulau]

Hello,

All of the sudden I lost CIMC connectivity to one of our UCS C220 platforms. When I went to look at it, it is continuously

beeping a single long beep ,with the status led flashing amber. I power cycled it but still no CIMC. The bare metal RHEL

OS does boot and am able to ssh to it. I connected a local monitor to the system when I power cycled it, but did  not see any warnings on screen.

Any idea's where I should start troubleshooting?

Thank You

First thing we need is to get CIMC back and then go from there, so can you remove the power cables for 3-5 minutes, plug them back and let me know if still cant access CIMC?

Thanks Saurabh, Kerry,

Powering off for 5 minutes brought the CIMC back, and then I could see that power supply 1

was offline. Replaced it and no more fault.

Thanks for your help.

John,

probably there's memory leak in CIMC

for Beep issue:

Table 5-3 gives a translation between the beep intervals and potential issues.

I would suggest you to open a TAC case and get the logs analysed.
