Solaris平台下的硬盘增设方法小结

1. 关闭系统,进入PROM状态 # init 0 ok (PROM状态提示)

2. 在PROM状态提示符下确认当前系统所连接的SCSI设备状况 ok probe-scsi 或 ok 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 盘之信息没有出现时,请按下述方法进行确认.

3. 重新起动系统 ok 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.

4. 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.

执行例# format

(注1) 当改变其他分区尺寸时, 浮动区(Free Hog)用于在容量范围内进行自动调 节.

(注2) 分区容量的具体指定方法为:

容量数值后面加"b": 指定块数.

容量数值后面加"c": 指定柱面数.

容量数值后面加"mb": 指定MB数.

建议采用"mb",以兆字节为单位指定分区容量.

5. 生成新的文件系统用newfs命令将所划分的分区生成为新的文件系统.

#/usr/sbin/newfs /dev/rdsk/c0t1d0s7 (CR)

如果在上述过程中将整个硬盘指定为一个分区,可执行下述命令.

# /usr/sbin/newfs /dev/rdsk/c0t1d0s2 (CR)

6. 检查新生成的文件系统

用fsck命令检查新生成的文件系统是否正确.

# /usr/sbin/fsck /dev/rdsk/c0t1d0s7 (CR)

如果在上述过程中将整个硬盘指定为一个分区,可执行下述命令.

# /usr/sbin/fsck /dev/rdsk/c0t1d0s2 (CR)

7. 安装新生成的文件系统

建立安装用目录后用mount命令进行安装.

例如,要将第7分区之文件系统用于home1时,可执行下述命令.# mkdir /home1 (CR)
# mount /dev/dsk/c0t1d0s7 /home1 (CR)8. 确认安装结果 用df命令确认安装结果.# df -k (CR)9. 自动安装新设文件系统

为在系统起动时自动安装新设文件系统,修改/etc/vfstab文件.# vi /etc/vfstab (CR)
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
:
/dev/dsk/c0t3d0s7 /dev/rdsk/c0t3d0s7 /home1 ufs 6 yes -10. 重新起动系统# sync;sync;reboot (CR)
