Useful IPMI commands on SuperMicro AOC-IPMI20 for Serial-Over-LAN Console

SuperMicro ipmitool

# service ipmi stop

SuperMicro Configuration Tool Began to work 

# ./ipmicfg-linux.x86_64.static -m
IP=192.168.1.21 MAC=00:30:48:56:A8:14
# ./ipmicfg-linux.x86_64.static -k
Net Mask=255.255.255.0

Common ipmitool commands

# ipmitool -l open shell
# ipmitool -l open mc reset cold
# ipmitool -I open lan print
# ipmitool -l open session info all


Set higher baudrate on BMC

  • IPMIv2 only uses CTS/RTS (RTS/CTS);
# ipmitool -l open sol info 1
# ipmitool -l open sol set help
# ipmitool -l open sol set volatile-bit-rate 115.2 1
# ipmitool -l open sol set non-volatile-bit-rate 115.2 1


Remote IPMI shell

# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN shell
# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN sol activate
# ipmitool -I lanplus -H 192.168.1.21 -U ADMIN chassis power reset

Using the Serial BIOS

  • http://buttersideup.com/docs/howto/IPMI_on_Debian.html
  • The serial BIOS interface is a bit brain damaged in that it does not recognise the "F11", and "F12" key escape codes that most terminal programs send, instead you can send "Esc-!", and "Esc-@" (yes very logical, as long as the '@' key is normally typed using 'Shift-2' - as on US keyboards, not miles away from the '2' key, as on many non-US keyboards). These escapes from HP, and Dell serial BIOS' may or may not be useful:
Defined As     F1     F2     F3     F4     F5     F6     F7     F8     F9     F10    F11    F12
Keyboard Entry <ESC>1 <ESC>2 <ESC>3 <ESC>4 <ESC>5 <ESC>6 <ESC>7 <ESC>8 <ESC>9 <ESC>0 <ESC>! <ESC>@

Defined As     Home   End    Insert Delete PageUp PageDn
Keyboard Entry <ESC>h <ESC>k <ESC>+ <ESC>- <ESC>? <ESC>/

Use the <ESC><Ctrl><M> key sequence for <Ctrl><M>

Use the <ESC><Ctrl><H> key sequence for <Ctrl><H>

Use the <ESC><Ctrl><I> key sequence for <Ctrl><I>

Use the <ESC><Ctrl><J> key sequence for <Ctrl><J>

Use the <ESC><X><X> key sequence for <Alt><x>, where x is any letter key, and X is the upper case of that key


Fedora 13

  • Set console=ttyS1,19200n8 last for udev to automatically configure serial console on boot.
