<h1 class="topictitle1">Multiple tape drives in a 3494 Tape Library Dataserver</h1>
|
|
<div><p>Larger iSeries™ servers can reduce backup times by breaking
|
|
the operation into multiple concurrent save operations to multiple devices.</p>
|
|
<p>Not all connections between an iSeries server and the 3494 Automated
|
|
Tape Library Dataserver are valid. A single iSeries server can be connected to multiple
|
|
tape drive controllers. However, a single partition in an iSeries server
|
|
cannot be connected twice to the same tape drive controller, as this creates
|
|
a serial number conflict and results in nonfunctional drives. This scenario
|
|
might be evident during an IPL.</p>
|
|
<p>The following figure shows a supported configuration. The cable attaches
|
|
the iSeries server
|
|
to the tape drives.</p>
