The Intelligent Platform Management Interface (IPMI) specification is an Intel led standard which defines a set of common interfaces to a computer system which system administrators can use to monitor system health and manage the system.

DELL PE sc1435 have Standard Baseboard Management Controller with IPMI 2.0 support,so we can use this feature to manage our servers .

IPMItool is a command line utility for managing and configuring systems with IPMI support. This tool allows you the ability to communicate directly with the IPMI card installed in the server or over a network using TCP/IP.

First , Power On PowerEdge sc1435 server ,when BIOS check , input Ctrl-E to keyboard:

then configure IMPI to the server, and also you can refer this guide document:
http://www.dell.com/downloads/global/power/ps4q04-20040204-Murphy.pdf

then,start OS(Debian Lenny 5.0.3 amd64)

#apt-get install ipmitool

#apt-get install openipmi libopenipmi-dev

# modprobe ipmi_watchdog
# modprobe ipmi_poweroff
# modprobe ipmi_devintf
# modprobe ipmi_si
# modprobe ipmi_msghandler

Check if ipmi_xxx related kernel modules have loaded or not:

# lsmod |grep ipmi
ipmi_si 43628 2
ipmi_devintf 13200 0
ipmi_poweroff 13776 0
ipmi_watchdog 22896 0
ipmi_msghandler 38520 4 ipmi_si,ipmi_devintf,ipmi_poweroff,ipmi_watchdog

Now,as you see, it have loaded,create the IPMI device:

mknod /dev/ipmi0 c `cat /proc/devices | grep ipmidev | awk '{print $1}' ` 0

you can then use ipmitool now !

#ipmitool lan print 1

                        :     O=OEM

and you can reconfigure ipmi sets:

# ipmitool -I open lan set 1 ipsrc static

# ipmitool -I open lan set 1 ipaddr 192.168.101.154
Setting LAN IP Address to 192.168.101.154

# ipmitool -I open lan set 1 defgw ipaddr 192.168.101.1
Setting LAN Default Gateway IP to 192.168.101.1

# ipmitool -I open lan set 1 netmask 255.255.255.0
Setting LAN Subnet Mask to 255.255.255.0

# ipmitool -I open lan set 1 access on

#ipmitool -I open user set password 2 askwan.com

logo to another server,check the server's system event log:

# ipmitool -I lan -H 192.168.101.154 -U root -a sel list

OS: CentOS 5
NXserver : 3.4


for security reasons, Nomachine  can't allowed you to login with user root default!
if you want to login with root,then you can do followings!


or


then  


now,you can login with user root!

System has been restarted everything seemed normal, the application starts normally! View the system boot log, there is no exception, the specific reasons for this situation also unknown now! It seems  need to continue to observe.

However, open system, found that swap partition 0

Is it did not installed the system swap partition?

output Nothing, there is no swap partition indeed !
this System has 4G mem, so additional 8G swap space manually



Re-examine swap partition:

USE top TO CHECK  

OK! write this to fstab file,so it can valid at system start time !

解压然后编译，编译参数

如编译报错：

这是缺少libperl-dev开发库,安装上

然后make ;make install
可以用snmpconf配置snmpd.conf，也可用例子文件

然后根据需要修改此文件

启动


测试
