|
||
|
|
<p>You should always use the Power Down System (PWRDWNSYS) command when you
|
||
|
|
power down a system that is connected with OptiConnect. If you do not use
|
||
|
|
the PWRDWNSYS command, you could experience difficulties with system-to-system
|
||
|
|
connections.</p>
|
||
|
|
<p>Certain conditions can cause system-to-system connections to become inoperative.
|
||
|
|
Performing an IPL on one of the systems is the only way to reestablish these
|
||
|
|
connections.</p>
|
||
|
|
<p>You can avoid these conditions by using the PWRDWNSYS command. However,
|
||
|
|
some conditions, such as abnormal operations, or loss of power on one system
|
||
|
|
in the OptiConnect network, may make it necessary to perform an IPL. Additional
|
||
|
|
examples are:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Emergency power off (EPO)</li>
|
||
|
|
<li>Utility or uninterruptible power supply failure</li>
|
||
|
|
<li>Hardware failures</li>
|
||
|
|
<li>Interrupted IPLs or failure of an IPL</li></ul>
|
||
|
|
<p>If you suspect one of these conditions has occurred, check the status of
|
||
|
|
the bus expansion adapter by using the Work with Hardware Resources (WRKHDWRSC)
|
||
|
|
command. For more information on using this command, see <a href="rzau3whrsc.htm#whrsc">Work with hardware resources (WRKHDWRSC)</a>.
|
||
|
|
Report hardware failures by contacting your IBM® Service Representative.</p>
