78 Using the iSCSI Gateway Service
If there are multiple iSCSI portals on one MP Router, configuration information, such as IQN-to-WWN
mapping and CHAP secrets, is automatically shared among the portals. If there are iSCSI portals on more
than one MP Router, you can use the IP fabric configuration server (iFCS) to control the sharing of iSCSI
gateway configuration information across multiple MP Routers.
Summary of configuration steps
The configuration of an iSCSI gateway is illustrated in Figure 16.
Figure 16 iSCSI gateway configuration
The steps required to configure an iSCSI gateway are summarized below and detailed in the referenced
sections.
1. Configure an iSCSI portal on the MP Router.
Use the procedure in ”Configuring an iSCSI portal” on page 78.
2. Optional: Create zones with the iSCSI initiators and the Fibre Channel targets as zone members.
See ”Configuring iSCSI gateway zones” on page 79 for details.
3. Optional: Configure CHAP access control for the Fibre Channel targets.
Use the procedure in ”Configuring CHAP” on page 80 to configure the shared secret for the Fibre
Channel targets.
4. Install and configure the iSCSI initiator driver.
You must assign a unique IQN to the driver. If you configured CHAP for the target in step 3, you must
configure matching CHAP shared secrets. See the iSCSI driver documentation for details on how to
configure the driver.
NOTE: All ports on an MP Router are optical ports. To connect a port to a copper network, use an
optical-to-copper converter.
Configuring an iSCSI portal
Use the following procedure to configure a port as an iSCSI portal:
1. Issue the portStop command to stop the port.
2. Issue the portType command to set the port for GigE.
3. Issue the portCfgGige to set the GigE port parameters, ensuring that the port is set as an iSCSI GigE
port.
4. Issue the portStart command to start the port.
