<div><p>A communication line must be created between the tape library and
|
|
the library manager.</p>
|
|
<p>The 3494 tape library requires a communications line for the library manager
|
|
functions. The communication line can be RS232 ASYNC, LAN, or TCP/IP. Before
|
|
the 3494 tape library can be varied on, the communication line needs to be
|
|
specified in the ROBOTDEV or ROBOTHOST parameter in the tape library device
|
|
description.</p>
|
|
<p>To create the data link between the tape library and the library manager
|
|
use the Configure Device MLB (CFGDEVMLB) command. This command uses the required
|
|
input parameters to configure and connect the communications line to the tape
|
|
library device description and attempts to vary on the tape library.</p>
|
|
<div class="note"><span class="notetitle">Notes:</span> <ol><li>To use the LAN connection, you must also add the LAN host to the 3494
|
|
Library Manager. For complete instructions, see the 3494 documentation.</li>
|
|
<li>If your 3494 tape library has the high-availability option installed so
|
|
that your 3494 tape library uses two Library Manager personal computers, you
|
|
need to configure two communication lines, one for each Library Manager personal
|
|
computer.</li>
|
|
</ol>
|
|
</div>
|
|
<p>Use one of the following procedures to create a data link.</p>
