For beginners to learn the mount command, there will be a lot of questions. In fact, I want to know more about the special nature of the linux system. Linux is based on a file system. All devices correspond to the following devices:/dev. For example:

Sd * represents the scic Hard Disk
Therefore, when you need to access devices, we need to
A friend came to me and said they had switched the previously stored to AIX direct-attached storage to a storage network with a fibre switch, and the RAC failed to start, allowing me to support it.

Linux.
In this step of preparation for installation of Red Hat Linux, you should begin to consider the number and size of partitions to be used in your new operating system. "How many partitions" has always been a controversial issue in the Linux community. Before the conclusion is reached, we can say that there are as many people discussing this issue as available partition la S.
In view of the above situation, unless otherwise, you should create at least the following partitions: swap,/boot,

After partitioning and formatting the file system, the final mount is reached. After mounting, the disk device can be used.
