HPUX11i上使用make_tape_recovery －A命令实现对系统的备份

准备知识（摘自《HP-UX 系统和网络管理I》：

frecover对于恢复一些文件和目录已经足够了。然而，如果root盘坏了，系统将无法启动，它不可能再启动内核，更别说恢复文件和目录了。

make_recovery就是为这种情况设计的。make_recovery可以创建一个能自启的磁带镜像，包括在root卷集中有选择的关键的文件和目录。

如果root卷集中的任何磁盘坏了，管理员可以用恢复磁带恢复一个最小的系统，从恢复磁带启动将：

1，在root盘重建启动区

2，在vg00里的磁盘上重建逻辑卷和文件系统

3，恢复已选择的关键文件和目录到root盘

由make_recovery恢复的关键文件使得运行frecover成为可能，frecover从最近的磁带备份来恢复其他文件和目录。

 

充要条件：

1，确保安装了Ignite－UX

make_recovery是Ignite-UX的一个部分，在HP－UX的标准安装中没有捆绑，需要用户自定义安装。安装完毕之后，可以通过命令“swlist”查看是否存在：

Ignite-UX-11-11       C.6.1.44       HP-UX Installation Utilities for Installing 11.11 Systems

2，确保磁带机和主机连接且状态良好

通过命令“# ioscan -fnCtape”查看磁带机状态：

# ioscan -fnCtape
Class     I  H/W Path     Driver S/W State   H/W Type     Description
=====================================================================
tape      0  0/0/1/0.0.0  stape CLAIMED     DEVICE       HP      C5683A
                         /dev/rmt/0m            /dev/rmt/c0t0d0BESTn
                         /dev/rmt/0mb           /dev/rmt/c0t0d0BESTnb
                         /dev/rmt/0mn           /dev/rmt/c0t0d0DDS  
                         /dev/rmt/0mnb          /dev/rmt/c0t0d0DDSb 
                         /dev/rmt/c0t0d0BEST    /dev/rmt/c0t0d0DDSn 
                         /dev/rmt/c0t0d0BESTb   /dev/rmt/c0t0d0DDSnb

3，放入磁带，通过“tar”命令测试磁带机是否可用

# tar -cvf /dev/rmt/0m myfile

 

执行命令make_tape_recovery -A测试是否能对系统进行备份（注：在HPUX11i系统中，make_recovery命令无法实现，取而代之的是make_tape_recovery命令），以下是整个备份过程：
