Editing a CHAP secret
1. Launch the iSCSI Target Gateway Admin module as described on page 171.
2. Select the CHAP tab.
3. Click Change CHAP Secret.
You can edit the CHAP secret but not the CHAP user name.
4. Fill in the fields in the dialog box to edit a CHAP secret.
Binding or Removing CHAP users
1. Launch the iSCSI Target Gateway Admin module as described on page 171.
2. Select the CHAP tab.
3. Click Bind/Remove Chap(s).
4. Select a virtual target
5. Enter a new CHAP user, if necessary.
6. Select the CHAP users and click Add or Remove to move them into the appropriate list
(unassociated or associated CHAP users).
7. Cli ck Apply.
Configuring an iSCSI Fibre Channel Zone
After you have finished setting up the iSCSI target gateway and whenever you later modify the iSCSI
virtual target mappings, you must create an iSCSI Fibre Channel zone to allow the system’s virtual
initiators (logical FC devices that represent iSCSI initiators) to communicate in a zoned FC
environment with the physical devices to which you have mapped the iSCSI virtual targets.
The procedures in this section show you how to create this zone and add it to the fabric’s zone
database.
• If you already have zone configurations defined in your fabric, you will also be able to add the
zone that you create here to some or all of these configurations by selecting them from a list.
• If a defined configuration is currently effective in the fabric and you add your iSCSI FC zone to
that configuration, the configuration is automatically re-enabled to include this zone.
NOTE
If you do not have a zoning license or no zoning implemented, you do not need to create one for iSCSI
target gateway service.
The following default zoning conditions apply:
• If default zoning is set to No Access, then creating an iSCSI Fibre Channel zone is mandatory
as there is no way for the devices to talk to each other without one.
• If default zoning is set to All Access and no effective zone configuration, then you can create an
iSCSI Fibre Channel zone and add it to a defined configuration, but you do not need to enable
the defined configuration. Since your default zoning is All Access with no effective zone
configuration, all devices can already talk to each other. However, to avoid SAN congestion in
the future, you should implement a zoning plan for your devices.
