Step 6: Install the QLdirect Failover Driver
The QLdirect driver provides two main features with the enhanced miniport driver
under Windows NT and Windows 2000:
■ Failover of a target device between two HBAs
■ Optimization of the I/O path
■ Improved performance and CPU usage
If you are not using Windows NT or Windows 2000, or if you are not using QLdirect
features, skip to section 2.3.7.
Install QLdirect using the InstallShield script provided on the distribution CD.
Verification QLdirect operates transparently, so there are no visible effects of
failover. To verify the operation of QLdirect, force a failover by starting
an I/O stream to a dual-ported device, then remove the cable for one
path to the device. Monitor the event log; a failover message is
generated when QLdirect performs a failover. Verification may take
a couple of minutes, depending on various system parameters.
Reconnect the primary path cable; QLdirect should failback to the
primary path within seconds. A failback is logged into the event log.

Step 7: Configure the Disks in the Operating System
When all hardware and configuration is complete for Fibre Channel subsystems,
use the appropriate operating system utilities to enable devices, assign drive letters
or logical names, initialize file systems, etc., for each device or LUN on the system.

Step 8: Install the IP Communications Driver
Optionally, install the IP communications driver. To use the NDIS driver to enable
IP traffic over the Fibre Channel, install that device driver and its configuration utility.
