Dynamic Mapping

</h1>
<a name="wp1073428"> </a><p class="pBody">
When you configure dynamic mapping the IPS module or MPS-14/2 module imports all Fibre Channel 
targets to the iSCSI domain and maps each physical Fibre Channel target port as one iSCSI target. That 
is, all  LUs accessible through the physical storage target port are available as iSCSI LUs with the same 
LU number (LUN) as in the physical Fibre Channel target port.

</p>
<a name="wp1073434"> </a><p class="pBody">
The iSCSI target node name is created automatically using the iSCSI qualified name (IQN) format. The 
iSCSI qualified name is restricted to a maximum name length of 223 alphanumeric characters and a 
minimum length of 16 characters.

</p>
<a name="wp1073435"> </a><p class="pBody">
The IPS module or MPS-14/2 module creates an IQN formatted iSCSI target node name using the 
following conventions because the name must be unique in the SAN:

<strong>Note	&nbsp;&nbsp;&nbsp;</strong> If you have configured a switch name, then the switch name is used instead of the management IP 
address. If you have not configured a switch name, the management IP address is used.

With this convention, each IPS port in a Cisco MDS 9000 Family switch creates a unique iSCSI target 
node name for the same Fibre Channel target port in the SAN.

</p>
<a name="wp1073451"> </a><p class="pBody">
For example, if an iSCSI target was created for a Fibre Channel target port with pWWN 
31:00:11:22:33:44:55:66 and that pWWN contains LUN 0, LUN 1, and LUN 2, those LUNs would 
become available to an IP host through the iSCSI target node name iqn.1987-05.com.cisco:05.

<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Each iSCSI initiator may not have access to all targets depending on the configured access control 
mechanisms (see the <a href="ciscsi016.html">&quot;iSCSI Access Control&quot; topic</a>).
