Authenticating Targets (CHAP)

The ISP4010 firmware utilizes the challenge handshake authentication protocol
(CHAP) as an authentication mechanism between the iSCSI initiators
(QLA4010/4010C HBAs) and the devices to which they are attached (targets).
Authentication can be disabled or enabled for a specific target or for all targets
attached to the QLA4010/4010C HBA.
NOTE:
Perform the following steps to set up CHAP for the QLA4010/4010C HBA and the
attached targets:
1. Select an HBA from the HBA tree.
2. Click the Target Settings tab.
3. Click Config Authentication.

Enable. When the check box is selected in this read-only field, the target
is visible and accessible to the QLA4010/4010C. When this check box is
not selected, the target is visible, but not accessible, to the
QLA4010/4010C.
Dynamic. When the check box is selected in this read-only field, the target
has been identified, but is not yet visible or accessible to the
QLA4010/4010C.
Default Timeout. This column indicates the timeout interval that the
QLA4010/4010C firmware uses for timing out commands or PDUs created
and transmitted by the QLA4010/4010C that are not related to an IOCB.
For example, in session mode the firmware generates Login Command
and Text Command PDUs. These PDUs are not related to an IOCB;
therefore, they have no inherent timeout value. In this case, the firmware
uses the value specified in this column as the timeout interval for the Login
Command and Text Command PDUs. The firmware also uses the timeout
interval specified in this field for timing out Task Management commands
that are generated by the firmware as part of error recovery or in response
to a mailbox command that results in a Task Management command. The
default value for this column is 10 seconds. Valid values are in the
range 0–65535.
The targets attached to the QLA4010/4010C HBA must be programmed
for or support CHAP.
