operations, the CLI displays an appropriate message. In this case,
you can open the controller for read-only operations.
If you open a controller with read-only access, you can use only the
commands that do not change the controller configuration. If you
execute a command that is not valid in read-only mode, the CLI
displays an appropriate error message.
After you open a controller, you are ready to work with the
controller attributes. See Understanding Controller Attributes on
page 3-5 for information on how to work with controller attributes
and perform controller tasks.
In this chapter, all examples use the controller named HPN0.
Opening and Closing a Controller
Before you can perform operations on a controller, you must first
open it. You can open a controller in either snapshot, read/write, or
read-only mode on the following operating systems:
■ Windows NT
■ Windows 2000 (basic disks only)
■ NetWare
■ UNIX
The following sections describe how to open and close controllers on
the listed operating systems.
Displaying a List of Available Controllers
Before you open a controller, you may first want to use the
controller list command to display a list of controllers, as in
the following example. In the example, the Adapter Name column
indicates that HPN0 is the name of the controller installed on the
computer. The example also indicates the controller’s path, which is
\\.\
