5 Using the SANsurfer application
This chapter provides an overview of the QLogic* SANsurfer application that can be used by
advanced users to customize the configuration of the Fibre Channel expansion card when it is
installed in a blade server. For more detailed information, see the SANsurfer application online help.
Overview of the QLogic* SANsurfer application
The QLogic SANsurfer application is used to configure a storage area network (SAN) environment
made up of Fibre Channel host bus adapters (HBAs). It is a network-capable application that can
connect to and configure remote systems, enabling centralized management and configuration of an
entire SAN containing HBA components, storage devices, and host systems.
You can use the SANsurfer application to manage and control one or more Fibre Channel expansion
cards that are installed on local or remote systems. The SANsurfer application is used, along with
problem determination procedures (PDPs), on new or existing installations to help diagnose Fibre
Channel (FC) subsystem problems in adapters, controllers, and devices that are attached to the FC
fabric or loop.
You can also perform the following operations using the SANsurfer application to configure devices
in your system:
• Disable (unconfigure) a device on a host bus adapter: When a device is set as unconfigured, it is
not recognized by the HBA and is not accessible to the HBA on that system.
• Enable a device: This operation adds a device and makes it accessible to the HBA on that
system.
• Designate a path as an alternate or preferred path: When a device is accessible from more than
one adapter in the same system, you can assign one path as the preferred path and the other path
as an alternate path. If the preferred path fails, the system switches to the alternate path to make
sure that the transfer of data is not interrupted.
Installation and system requirements
Make sure that you are using the latest version of the SANsurfer application for the Fibre Channel
expansion card. For the latest information about the SANsurfer application, go to
http://www.intel.com/. The latest instructions and system requirements are in the documentation that
come with the applications.
Features
The SANsurfer application lets you:
• Set the SANsurfer application options
• Connect to hosts
• Disconnect from a host
• View detailed event and alarm-log information v Use host-to-host SAN configuration policies
• Configure port devices
• Use logical unit number (LUN) level configuration
• Monitor in real-time to see when failovers occur, using the Failover Watcher
