NOTE:

If installing Command View TL on the same management station as Command View EVA

v10.2, special steps must be taken. For full instructions, see the HP StoreEver Command View for

User interfaces

Four different user interfaces (UIs) can be used to control the Interface Manager card. These UIs
are provided by the Interface Manager card or by Command View TL. This chapter explains the
purpose and use of each UI. The UIs are as follows:

NOTE:

The Interface Manager card is only used with EML and ESL E-Series tape libraries.

Serial—Uses a command line interface (CLI) and connects directly to the Interface Manager
card through an RS232 serial interface rather than through the LAN.

Telnet—Uses the same CLI as the serial interface, but requires the IP address of the Interface
Manager card to initiate the session. This IP address can be set through the Interface Manager
card serial interface or cascade port or, on ESL E-Series libraries, through the library Operator
Control Panel (OCP). The advantage of using Telnet over the serial interface is that users can
Telnet from any client machine that is on the LAN; a separate serial connection is not needed.
You can disable Telnet (see

set inet telnet (page 206)

).

NOTE:

If you use Telnet to change the IP address of the Interface Manager card or library,

you must log in to a new Telnet session with the new IP address.

SSH—This protocol uses the same CLI as the Telnet and serial interfaces, but over a more
secure channel. Different SSH client applications are available for various operating systems.
When connected via SSH, use it in the exact way you would use Telnet.

Command View TL—Is a browser-based graphical user interface (GUI). This is the preferred
UI for controlling the Interface Manager card because it provides the most functionality and
should be used in most circumstances. From any client on the LAN, you can use a browser to
access Command View TL, which is hosted on a management station. For more information
on using Command View TL, see

Command View TL GUI (page 15)

.

You can have multiple sessions open at the same time (serial, Telnet, SSH, or Command View TL).
If a write operation is in progress in one session, subsequent write operations for that library from
other sessions will be denied.

Network configuration overview

With the EML E-Series tape library, the external LAN communicates directly to the Interface Manager
card using the card's network IP address. The Interface Manager card processes requests and
relays information to the FC interface controllers.

ESL E-Series libraries contain a private LAN internal to the library. The library cabinet controller
provides a bridge between the external LAN and the library internal LAN and Interface Manager
card.

ESL E-Series and EML E-Series tape libraries with LTO4 or later tape drives also contain an internal
network switch to connect the LTO4 and later tape drives to the Interface Manager or library
internal LAN.

card in the various libraries.
