> # Configuring Static Mapping

> ## Detailed Steps

> To configure static mapping for an iSCSI initiator using Device Manager, follow these steps:

> 1. Select IP > iSCSI.

> You see the iSCSI configuration. The Initiators tab is the default.

> 2. Click Create to create an iSCSI initiator.

> You see the Create iSCSI Initiators dialog box.

> 3. Set the iSCSI node name or IP address and VSAN membership.
> 4. In the Node WWN section, check the Persistent check box.
> 5. Check the System Assigned check box if you want the switch to assign the nWWN or leave this unchecked and set the Static WWN field.
> 6. In the Port WWN section, check the Persistent check box if you want to statically map pWWNs to the iSCSI initiator.
> 7. If persistent, check the System Assigned check box and set the number of pWWNs to reserve for this iSCSI initiator if you want the switch to assign pWWNs. Alternately, you can leave this unchecked and set one or more pWWNs for this iSCSI initiator.
> 8. (Optional) Set the AuthUser field if authentication is enabled. Also see the "iSCSI Session Authentication" topic.
> 9. Click Create to create this iSCSI initiator.

> Note If the system-assign option is used to configure WWNs for an iSCSI initiator, when the configuration is saved to an ASCII file the system-assigned WWNs are also saved. Subsequently if you perform a write erase, you must manually delete the WWN configuration from the ASCII file. Failing to do so can cause duplicate WWN assignments if the ASCII configuration file is reapplied on the switch.
