Troubleshooting iSCSI Issues
There are several types of issues you can experience with iSCSI, including the following:
• Troubleshooting iSCSI Authentication, page 5-31
• Configuring Authentication, page 5-32
• Troubleshooting Username/Password Configuration, page 5-33
• Troubleshooting Radius Configuration, page 5-33
• Troubleshooting Radius Routing Configuration, page 5-36
• Troubleshooting Dynamic iSCSI Configuration, page 5-36
Troubleshooting iSCSI Authentication
iSCSI user login authentication is required with the Cisco MDS 9000 Family switch. There are two ways
of the getting iSCSI users authenticated: either locally configured the in the switch’s configuration file,
or using the Radius server database.
Figure 5-11 shows a successful iSCSI login for the Windows 2000 driver.

On Solaris systems, a successful login is found in the /var/adm/messages directory, and should look
similar to the following example:
