一、在SUN E250上增加大容量硬盘

SUN E250服务器是一款可插入六块硬盘的工作组服务器，SUN公司官方称此服务器只可使用36GB以下的SCSI硬盘，通过实践我们成功的在SUN E250上插入了一块18GB的SCSI硬盘安装操作系统，五块146GB的SCSI硬盘作数据存储，具体操作过程如下：

 1、先插入18GB硬盘，安装Solaris 9操作系统。

 2、关闭系统，调整每一块SCSI大容量硬盘的ID号，使之不重复后，插入机器中。

 3、开机按Stop-A进入PROM状态 % init 0 ok (PROM状态提示) 。

 4、在PROM状态提示符下确认当前系统所连接的SCSI设备状况键入

 probe-scsi 或 probe-scsi-all

这时，系统将显示所能识别的SCSI设备极其设备号(Target ID)，如果新连接的硬盘信息没有出现时,请按下述方法进行确认。

1) 检查设备号是否重复?

Target-ID SunOS 4.xSolaris 2.x

3 内藏硬盘　

1 硬盘 通常与SunOS 4.x一致.

2 硬盘 当ID不重复时, 4,5也

0 硬盘 可以用于硬盘.

4 磁带 　

5 磁带 　

6 CD-ROM CD-ROM

2) 检查电缆,插口,终端器等物理连接是否无误?

3) SCSI电缆的总长度是否在6米以内?

 5、重新起动系统，键入

 boot -r

注意，只有加入"-r"选项时, 系统在起动时才给所识别了的设备(包括SCSI设备) 生成相应的设备文件。

 6、对新增设的硬盘进行盘区划分

进入系统状态后,执行format命令，对新增设的硬盘进行盘区划分。
