<h4 id="rzahqtroubmultnwsds">Multiple NWSDs defined to use the same hosted system hardware</h4>
|
|
<p>It is possible to define multiple network server descriptions (NWSDs) to
|
|
control the hardware of a particular Integrated xSeries® Server (IXS), xSeries system,
|
|
or IBM® BladeCenter™ blade. For non-iSCSI attached servers, these
|
|
NWSDs must be in the same iSeries™ partition. However, for iSCSI attached
|
|
servers, these NWSDs can be defined on the same iSeries partition, another partition in the
|
|
same iSeries system, or on an entirely different iSeries system. For example, you may have
|
|
an NWSD defined to use an xSeries system for production work during
|
|
normal business hours and another NWSD defined to use the same xSeries system at
|
|
other times.</p>
|
|
<p>Only one NWSD can use a particular piece of server hardware at any point
|
|
in time. Therefore, if there are multiple NWSDs defined to run on the same
|
|
hardware and one of them is currently using it, the others are not allowed
|
|
to start until the NWSD that is currently using the hardware is shut down
|
|
(varied off . This protects against one NWSD inadvertently taking over the
|
|
hardware that is being used by another NWSD.</p>
|
|
<p>If you are having problems starting an NWSD and the server hardware is
|
|
currently being used by another NWSD, then the correct way to transfer control
|
|
of the hardware from one NWSD to another NWSD is to first shut down the NWSD
|
|
that is currently using the hardware and then start the NWSD that needs to
|
|
use the hardware next.</p><img src="deltaend.gif" alt="End of change" />
