标题：制作U盘刷EXADATA

在XD需要刷机(方言重装操作系统),现在比较常见的是一种是使用PXE来刷机,另外一张是使用U盘制作启动盘来刷机.PXE配置起来比较麻烦,这里展示制作U盘刷机的过程.db节点和cell节点的制作方法基本相同,这里以cell节点的U盘制作为例说明制作过程
1. 前提条件
1) Linux 64位机器(最好直接在db和cell节点的机器上直接处理
2) U盘大小最少4G
3) 上传preconf.csv配置文件(使用java配置)
2. 下载image文件
通过888828.1文档找到image的名称,然后在edelivery中下载
3. 查看U盘盘符
[root@xifenfei tmp]# fdisk -l Disk /dev/sda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 3655 29358756 83 Linux /dev/sda2 3656 3916 2096482+ 82 Linux swap / Solaris Disk /dev/sdb: 4048 MB, 4048551936 bytes 128 heads, 9 sectors/track, 6864 cylinders Units = cylinders of 1152 * 512 = 589824 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 8 6864 3949096 b W95 FAT32
4. 上传压缩文件到服务器,并解压
unzip V36290-01.zip tar xvf cellImageMaker_11.2.3.2.1_LINUX.X64_130109-1.x86_64.tar
5. dl180内容
[root@xifenfei tmp]# cd dl180/ [root@xifenfei dl180]# ll total 92 drwxr-xr-x 3 root root 4096 Jan 9 22:33 boot drwxrwxr-x 2 root root 4096 Jan 9 22:34 doc drwxr-xr-x 2 root root 4096 Jan 9 22:33 grub drwxr-xr-x 17 root root 4096 Jan 9 22:33 initrd -rwxrwxr-x 1 root root 27485 Jan 9 22:34 makeImageMedia.sh drwxrwxr-x 3 root root 4096 Jan 9 22:34 patches -r-xr-xr-x 1 root root 39041 Mar 31 2011 README_FOR_FACTORY.txt drwxrwxr-x 4 root root 4096 Jan 9 22:34 tmp
6. 制作U盘启动
--执行makeImageMedia.sh命令
[root@xifenfei dl180]# ./makeImageMedia.sh -preconf /tmp/preconf.csv
Done. Pre config verification OK

The number of cylinders for this disk is set to 6864.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

现在已经制作完成，重启系统进入bios选择U盘启动,就可以对XD的cell节点进行刷机
