Sorry, it's a PE650, so no BMC.

ipmitool doesn't work, the kernel cannot find any drivers:

Sep 20 13:10:26 xxxx kernel: ipmi message handler version 39.0
Sep 20 13:10:26 xxxx kernel: IPMI System Interface driver.
Sep 20 13:10:27 xxxx kernel: ipmi_si: Unable to find any System Interface(s)

I know the slot from OMSA (actually, there's only one DIMM).

Is there a way to do that from OMSA?

Thanks,
