在虛擬機中模擬為CentOS系統添加硬盤

操作環境：VMware+CentOS5.0

實驗目的：為CentOS5.0系統添加一塊新磁盤，並mount到md目錄下

實驗過程：

步驟1：從VMare虛擬添加一塊8G的磁盤

菜單中選擇VM-->Settings，出現如下對話框（也可雙擊device界面）

按照提示做如下操作：選擇Add---> Hard Disk--->Create a new virtual disk---->next---->select a type(scsi)--->capity--->ok

第二步：啟動虛擬機，在Unix系統中添加磁盤，並劃分為一個分區

17. Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
18. Building a new DOS disklabel. Changes will remain in memory only,
19. until you decide to write them. After that, of course, the previous
20. content won't be recoverable.
23. The number of cylinders for this disk is set to 1044.
24. There is nothing wrong with that, but this is larger than 1024,
25. and could in certain setups cause problems with:
26. 1) software that runs at boot time (e.g., old versions of LILO)
27. 2) booting and partitioning software from other OSs
28. (e.g., DOS FDISK, OS/2 FDISK)
