IPMI

Some of these are old notes and may need verification or updating.

The default username and password are ADMIN/ADMIN (all caps), at least for Supermicro.

• Shares LAN1 port (nearest the Keyboard/Mouse ports)
• Test with machine turned off to avoid host OS interference
• Sonora Comm will use 'admin' username and change password to router password
• UDP Port 623 (may also need TCP Port 623?)
• BMC will not respond to ping even when working properly

Most new servers have IPMI settings in the BIOS. Older and cheaper BMCs require:

• Boot to IPMI support CD and flash BMC firmware
• IPMI 2.0
• RMCP+

• Bootable floppy images also on CD (needs Windows host)
• ipnmac.exe (from DOS) sets IP and MAC addresses
• Uses separate IP and MAC addresses (Broadcom NIC - use label on IPMI socket)
• Uses LAN1 MAC address (Intel NIC)

Log in via SSH if you are off-site.

We need the gateway IP and MAC addresses for the IPMI interface. You may be able to get them like this:

route -n
arp -n

I have not had to use this with recent CentOS 5 or 6. Skip to ipmitool section.

This will install and add commands to /etc/rc.local to run smagent which is needed for graceful shutdowns and reboots of the Linux OS:

wget ftp://ftp.supermicro.com/CDR-0010_2.10_IPMI_Server_Managment/IPMI_Solution/Linux/GPC_Agent/GPC_Agent-2.1-050406.tar.gz

tar -xzvf GPC_Agent-2.1-050406.tar.gz
cd GPC_Agent
./quickinstall      # choose option #2

Manual commands to do the same:

modprobe ipmi_devintf
modprobe ipmi_si type=kcs ports=0xca8 regspacings=4
/usr/supermicro/smagent &

lsmod

modprobe ipmi_msghandler
modprobe ipmi_si
modprobe ipmi_devintf

Works with IPMI kernel modules or smagent?

apt install ipmitool

modprobe ipmi_devintf

modprobe ipmi_devintf
modprobe ipmi_si

If ipmitool is not already installed:

yum install OpenIPMI-tools

wget http://dag.wieers.com/rpm/packages/ipmitool/ipmitool-1.8.8-1.el4.rf.i386.rpm
rpm -Uvh ipmitool-*

Display the current configuration:

ipmitool -v lan print 1

Do the configuration:

ipmitool -v lan set 1 ipsrc static
ipmitool -v lan set 1 ipaddr <youripmiipaddress>
ipmitool -v lan set 1 netmask <youripminetmask>
ipmitool -v lan set 1 defgw ipaddr <youripmigwip>
ipmitool -v lan set 1 defgw macaddr <youripmigwmac>
ipmitool -v lan set 1 arp respond on
ipmitool -v lan set 1 auth ADMIN MD5
ipmitool -v lan set 1 access on

Show the IPMI users:

ipmitool user list 1

Configure the IPMI user (the default Supermicro 'ADMIN' user is usually #2):

You may have trouble setting a password with symbols. Try setting a simple password, then use the GUI interface to set a more complicated one.

ipmitool -v user set password 2 <youripmipassword>
ipmitool -v user priv 2 4
ipmitool -v channel setaccess 1 2 link=on ipmi=on callin=on privilege=4
ipmitool -v user enable 2

Privilege level '4' is 'ADMINISTRATOR'.

Use ipmitool instead?

wget ftp://ftp.supermicro.com/CDR-0010_2.10_IPMI_Server_Managment/IPMI_Solution/Linux/Administrator/CLI/readme

wget ftp://ftp.supermicro.com/CDR-0010_2.10_IPMI_Server_Managment/IPMI_Solution/Linux/Administrator/CLI/ipmicli

Install IPMIView (assumes Java already installed on system):

mkdir -p ~/bin/IPMIView20
cd ~/bin/IPMIView20

wget ftp://ftp.supermicro.com/utility/IPMIView/Release/Jar/IPMIView20-Class_v2.6.44_Build080515.zip
unzip IPMIView20-Class_v2.6.44_Build080515.zip

chmod +x IPMIView20.sh

vim IPMIView20.sh

cd ~/bin/IPMIView20/
java -jar IPMIView20.jar

• You may need to refresh the list of hosts to see them as on-line
• Graceful reboot takes 1 minute to start
• Can be seen on redirected text console
• Redirected text console dies when login prompt is presented

Try this first!

Wait for the BMC to reboot.

Reboot the BMC, then try changing the configuration again:

ipmitool mc reset cold

Factory BMC Reset: http://www.supermicro.com/support/faqs/faq.cfm?faq=21709

Reset the BMC to factory defaults (from Supermicro FAQ):

ipmitool raw 0x3c 0x40

or, using a Supermicro tool:

./ipmicfg-linux.x86_64 -fdl

Supermicro IPMI controllers usually have a feature to install mainboard BIOS updates, as well as IPMI firmware updates, via the IPMI web interface. This is a licensed commercial feature and requires a license key to function.

Trial license keys are available from Supermicro. They can take a few days to get.

This feature can be a real benefit if you are having trouble updating a BIOS or if you need to update a BIOS remotely.

• Send an e-mail to sales@supermicro.com
• Ask for
  • Trial license key for IPMI BIOS updates
  • Part number SFT-OOB-LIC
• Include
  • Exact mainboard model number
  • MAC addresses on your mainboard including BMC

You can SSH into the BMC which will put you into SMASH.

You can switch to a BusyBox shell:

shell sh
