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 [ 42.526086] ipmi_si: Adding SMBIOS-specified smic state machine [ 42.526089] ipmi_si: Trying SMBIOS-specified smic state machine at i/o address 0xca9, slave address 0x1, 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.

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! |
