HUKs are available that support the following programs:
AIX with Fibre Channel Protocol (FCP) and iSCSI
Linux with FCP/iSCSI
HP-UX with FCP/iSCSI
Solaris Platform Edition (SPARC and x86) with FCP/iSCSI
VMWare ESX with FCP/iSCSI
Windows with FCP/iSCSI

17.3 Functions provided by Host Utilities

This section addresses the main functions of the Host Utilities.

17.3.1 Host configuration

On some operating systems such as Microsoft Windows and VMware ESX, the Host Utilities
alter the SCSI and path timeout values and HBA parameters. These timeouts are modified to
make sure of the best performance and to handle storage system events. Host Utilities make
sure that hosts correctly handle the behavior of the IBM N series storage system. On other
operating systems such as those based on Linux and UNIX, timeout parameters need to be
modified manually. For more information, see the Host Utilities Setup Guide.

17.3.2 IBM N series controller and LUN configuration

Host Utilities also include a tool called sanlun, which is a host-based utility that helps you
configure IBM N series controllers and LUNs. The sanlun tool bridges the namespace
between host and storage controller, collecting and reporting storage controller LUN
information. It then correlates this information with the host device filename or equivalent
entity. This process assists with debugging SAN configuration issues. The sanlun utility is
available in all operating systems except Windows.

17.4 Windows installation example

The following section provides an example of what is involved in installing the HUK onto
Windows and configuring your system to work with that software.

17.4.1 Installing and configuring Host Utilities

You must perform the following high-level steps to install and configure your HUK:
1. Verify your host and storage system configuration.
2. Confirm that your storage system is set up.
3. Configure the Fibre Channel HBAs and switches.
4. Check the media type setting of the Fibre Channel target ports.
5. Install an iSCSI software initiator or HBA.
6. Configure iSCSI options and security.
