2.3.1

Windows Event Log

The Windows event log is the main source of information for device driver problems

and events. Device drivers usually indicate only status by logging events in the

system event log. SANsurfer iSCSI HBA Manager agents also use the application

event log to report service errors, etc.

The miniport driver logs events for significant driver errors. Due to a limitation of the

Windows miniport driver interface, the miniport can log only two 32-bit values for

any event. Information about interpreting these event codes is in the eventlog.txt

file, which is shipped with the miniport driver.

2.3.2

SANsurfer iSCSI HBA Manager

The SANsurfer iSCSI HBA Manager provides the following diagnostic tools for

managing iSCSI HBAs:

■ Pinging a Target. Pinging verifies the connectivity between an HBA port and a

device port (see section 10.1).

■ Viewing the ARP Log. The address resolution protocol (ARP) cache keeps a

record of host port connections with other hardware (such as targets) on the

network (see section 10.2).

■ Viewing the Connection Error Log. The connection error log displays the

100 latest connection errors for an HBA port, thereby providing details about

connection problems with a device (see section 10.3).
