Dell OpenManage Server Administrator(OMSA)에서는 BIOS 설정을 미리 변경할 수 있습니다.
하지만 곧바로 NVRAM에 적재되는 것이 아니라 다음 rebooting이 있을 때 적용이 됩니다.
또한 Storage 부분에 RAID 구성이나 변경이 가능하기에 reboot 후 RAID Controller에서 구성을 하지 않아도 되는 번거로움이 가실 겁니다..
그리고 SNMP 서버를 구성한다거나 Dell ITA를 설치하여 snmp로 alert 메시지를 받아 모니터링 및 장애처리 한다면 서버 관리하는데 용이할 것입니다.
<커널 컴파일 하기>
- Dell Server
- OS : CentOS 5.5 x64
- Kernel : 2.6.18 -> 2.6.36
[root@localhost ~]# uname -a
Linux localhost.localdomain 2.6.18-194.26.1.el5 #1 SMP Tue Nov 9 12:54:40 EST 2010 i686 i686 i386 GNU/Linux
1. 커널 컴파일 전에 gcc, ncurses-devel 설치 및 package update
[root@localhost ~]# yum install -y gcc ncurses-devel
[root@localhost ~]# yum update
2. 최신 커널 다운로드(http://www.kernel.org/pub/linux/kernel/v2.6/)
[root@localhost ~]# cd /usr/src
[root@localhost ~]# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.tar.gz
[root@localhost ~]# tar xvfz linux-2.6.36.tar.gz
[root@localhost ~]# ln -s linux-2.6.36 linux
3. 커널 컴파일 설정
현재 사용하고 있는 커널 설정으로 컴파일 하기 위해 .config 설정 파일을 복사해서 진행
[root@localhost ~]# cd /usr/src/linux
[root@localhost linux]# make mrproper
[root@localhost linux]# make clean
[root@localhost linux]# cp /boot/config-`uname -r` ./.config
[root@localhost linux]# make menuconfig

General sertup 선택 -> enable deprecated sysfs features to support old userspace tools (NEW) 에서 "y" 키로 선택
-> Local Version 선택 후 커널 뒤에 붙을 release 이름 입력(-default를 붙혔다면 2.6.36-default로 생성 됨)
 |  |  |
설정이 끝났으면 .config 저장 후 Exit 로 종료
