利用mkcd製作AIX系統恢復光盤

mkcd是個好東西。利用它我們可以將rootvg備份到光盤上，儘管你小型機上的光驅是隻讀的。在做邏輯分區的服務器上我經常用這一招。好了，看看具體怎麼操作吧？

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.

步驟很簡單吧？先創建mksysb文件到磁盤，然後利用mkcd利用這個mksysb文件製成可引導的DVD格式的可引導文件。最後你只要將這個文件FTP到PC機刻錄成ISO格式的文件就可以了。你可以在系統需要恢復的時候在刻錄，盤片都省了。當然用磁帶恢復的速度還是快一些。
