Detailed Steps
</h2>
<a name="wp1105387"> </a><p class="pBody">
To replace a server with a spare server on a different switch, follow these steps:

</p>
<div class="pSmartList1"><ol type="1" class="pSmartList1">
<a name="wp1105393"> </a><li class="pSmartList1">In the DCNM-SAN window, select <b class="cBold">Tools&#160;&gt;&#160;NPV&#160;&gt;&#160;FlexAttach Replace Server</b>.
</li>
<a name="wp1105394"> </a><p class="pListBodyLevel1">
The Replace Server wizard is displayed. 

</p>
<a name="wp1105395"> </a><li class="pSmartList1">In the Replace Server wizard, click the <b class="cBold">With Spare Server on a Different NPV switch</b> radio button.
</li>
<a name="wp1105396"> </a><li class="pSmartList1">Click <b class="cBold">Next</b>.
</li>
<a name="wp1105397"> </a><p class="pListBodyLevel1">
The Failed Server Port window is displayed. 

</p>
<a name="wp1105398"> </a><li class="pSmartList1">In the Failed Server Port selection window, from the Select a Switch drop-down list, select the switch.
</li>
<a name="wp1105399"> </a><li class="pSmartList1">From the list of interfaces displayed, select the port from which the server needs to be detached.
</li>
<a name="wp1105400"> </a><li class="pSmartList1">Click <b class="cBold">Next</b>.
</li>
<a name="wp1105401"> </a><p class="pListBodyLevel1">
The New Port window is displayed.

</p>
<a name="wp1105402"> </a><li class="pSmartList1">In the New Port selection window, select the switch and the port on which the spare server is connected.
</li>
<a name="wp1105403"> </a><li class="pSmartList1">Click <b class="cBold">Next</b>.
</li>
<a name="wp1105404"> </a><p class="pListBodyLevel1">
The Server WWN window is displayed. 

</p>
<a name="wp1105405"> </a><p class="pListBodyLevel1">
In the Server WWN window, if the FlexAttach global mapping table is empty, the wizard automatically 
prefills the table with the interface virtual vPWWN of the source port to be replaced, and the vPWWN 
field is not editable. In this case, the <b class="cBold">Allow wizard to change from “pWWN to vPWWN” mapping to 
“interface to vPWWN” mapping</b> is treated as true.

</p>
<a name="wp1105406"> </a><p class="pListBodyLevel1">
If the FlexAttach global mapping table is not empty, the vPWWN field is blank and editable. From the 
drop-down list box which displays all existing entries from the global mapping table, select the vPWWN 
entry or type the required entry, and the new server physical port WWN.

</p>
<a name="wp1105407"> </a><p class="pListBodyLevel1">
Check the <b class="cBold">Allow wizard to change from “pWWN to vPWWN” mapping to “interface to vPWWN” 
mapping</b> check box to remove the pWWN to vPWWN entry from the CFS Region mapping table, and 
configure the mapping only at the interface.

</p>
<a name="wp1105408"> </a><li class="pSmartList1">Click <b class="cBold">Finish</b> to complete the FlexAttach configuration for the spare server.
</li>
