利用mkcd制作AIX系统恢复光盘

mkcd是个好东西。利用它我们可以将rootvg备份到光盘上，尽管你小型机上的光驱是只读的。在做逻辑分区的服务器上我经常用这一招。好了，看看具体怎么操作吧？

How to backup by mksysb on DVD
First you have to create the mksysb image to a file:
mksysb -i -e /dir/mksysb_file
Then you can create an iso files from the mksysb, to download to any windows to
burn the iso images:
mkcd -m /dir/mksysb_file -S -I /dir -L
-m says where is the mksysb image
-S stops the burning procedure and keeps the iso files. ( i think without this
you burn directly to your dvd or cd in the server, but i dont have one)
-I says where the iso files will be created
-L with this you say you want dvd images, without, is cd images.
Also, you must have in rootvg free space for temporary filesystems created
during the proces. 650 M if you choose CD, or 4.7 G if you chose DVD.

步骤很简单吧？先创建mksysb文件到磁盘，然后利用mkcd利用这个mksysb文件制成可引导的DVD格式的可引导文件。最后你只要将这个文件FTP到PC机刻录成ISO格式的文件就可以了。你可以在系统需要恢复的时候在刻录，盘片都省了。当然用磁带恢复的速度还是快一些。
