Enter the target secret (12-character

• Initiator secret
* If using CHAP with a single node only, use the initiator node name as the CHAP name.
If a CHAP name uses multi-byte characters, the server must be configured with the IQN name.
You must create the server first and then edit that server to add the CHAP name:
1. Create a new server and select CHAP not required, and enter the IQN.
2. Select CHAP required and enter the CHAP information.
3. Click OK. The server is created with both CHAP and the IQN information.
You can also edit an existing server to add the IQN if necessary:
1. Log off the target in the iSCSI initiator.
2. In the CMC, navigate to the server. Right-click and select Edit Server.
3. In the Authentication section, select CHAP not required and enter the IQN in the Initiator Node
Name field.
4. Select CHAP required and click OK.
5. Reconnect the volume in the iSCSI initiator.
iSCSI and CHAP terminology
The iSCSI and CHAP terms used vary based on the operating system and iSCSI initiator you are
using. The table below lists the terms for two common iSCSI initiators.
Table 80 iSCSI terminology
Linux VMWare Microsoft LeftHand OS
See the documentation for
the iSCSI initiator you are iSCSI Name Initiator Node Name Initiator Node Name
using. Linux iSCSI initiators
may use a command line
interface or a configuration
file.
CHAP Name Not used CHAP Name
CHAP Secret Target Secret Target Secret
N/A Secret Initiator Secret
NOTE: The initiator node name and secrets set in the CMC must match what you enter in the
server’s iSCSI initiator.
Example iSCSI configurations
The following iSCSI configuration examples use a Microsoft iSCSI initiator.
Figure 120 (page 244) illustrates the configuration for a single host authentication with CHAP not
required.
