The iSCSI initiator software comes with the operating system distribution. Its components include a kernel module, which is already compiled into the Linux kernel, and user space packages. For it to work properly, you must perform configuration tasks.

It is a good practice to change the initiator node name from the default name to one that includes the host name. That way the name is easier to use.
The following sections explain how to perform these tasks.
