Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
 

Hi,

Can someone help me to understand this issue, I am doing a test on my node doing multiple soft reboots after few cycles I observe below log comes after reboot. Although power cycle fixes this problem. But why during soft reboot issues hits?
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory

In addition to this still I observe below logs in dmesg

[root@localhost:/home/ctp_cmd 1]# dmesg | grep ipmi
[ 42.521720] ipmi message handler version 39.2
[ 42.526081] ipmi_si: probing via SMBIOS
[ 42.526084] ipmi_si: SMBIOS: io 0xca9 regsize 1 spacing 1 irq 0

[ 42.536888] ipmi_si: There appears to be no BMC at this location
[ 42.551137] ipmi device interface
[root@localhost:/home/ctp_cmd 2]#


Linux version is 3.14.39ltsi-WR7.0.0.27_standard.

Although all ipmi related modules are present
[root@localhost:/home/ctp_cmd 5]# lsmod | grep ipmi
ipmi_watchdog 15344 0
ipmi_devintf 5139 0
ipmi_si 41023 0
ipmi_msghandler 32498 3 ipmi_devintf,ipmi_watchdog,ipmi_si
[root@localhost:/home/ctp_cmd 6]#


Please suggest.

Thanks

You probably should start by reading the kernel IPMI driver documentation. Required kernel modules and configuration are specific to your system.
https://docs.kernel.org/driver-api/ipmi.html


Hope this helps. Good Luck!
