Initiator Identification

<a name="wp1073990"> </a><p class="pBody">
iSCSI hosts can be identified by the IPS module or MPS-14/2 module using the following:

</p>
<div class="pSmartList1"><ul class="pSmartList1">
<a name="wp1073993"> </a><li class="pSmartList1">iSCSI qualified name (IQN)
</li>
<a name="wp1073994"> </a><p class="pListBodyLevel1">
An iSCSI initiator is identified based on the iSCSI node name it provides in the iSCSI login. This 
mode can be useful if an iSCSI host has multiple IP addresses and you want to provide the same 
service independent of the IP address used by the host. An initiator with multiple IP addresses 
(multiple network interface cards&#8212;NICs) has one virtual N port on each IPS port to which it logs in.

</p>

</li>
<a name="wp1073999"> </a><p class="pListBodyLevel1">
An iSCSI initiator is identified based on the IP address of the iSCSI host. This mode is useful if an 
iSCSI host has multiple IP addresses and you want to provide different service-based on the IP 
address used by the host. It is also easier to get the IP address of a host compared to getting the iSCSI 
node name. A virtual N port is created for each IP address it uses to log in to iSCSI targets. If the 
host using one IP address logs in to multiple IPS ports, each IPS port will create one virtual N port 
for that IP address.
