You can use Xsan shell commands and conguration les to

work with a SAN from the command line.

You can use the shell commands and conguration les described here to access, set

up, and manage Xsan SANs, LUNs, storage pools, and volumes from the command line.

The Terminal application is the Mac OS X gateway to the BSD command-line interface

(UNIX shell command prompt). Each window in Terminal contains a complete

command-line execution context, called a shell, that is separate from all other

execution contexts.

Although you can use any shell of your choice, the examples in this book assume that

you’re using bash, the standard Mac OS X shell.

Using Shell Commands

The Xsan command-line utilities are located in /Library/Filesystems/Xsan/bin/, which is

part of the default shell search path.

Many commands used to manage Xsan must be executed by the root user (also

known as the superuser). If you get a message such as “permission denied,” the

command probably requires root user privileges.

To execute a single command with root user privileges, begin the command with sudo

(short for superuser do). For example:

$ sudo cvfsck -n MyVolume

If you haven’t used sudo recently, you’re prompted for the password for your

administrator account.

Sending Commands to Remote Computers

To use commands on a remote computer, rst use SSH to log in to the other computer:

$ ssh user@computer
