Step 4: Install Any Raid Filter Drivers - Qlogic SANsurfer FC HBA Manager User Manual

A
CAUTION!
At this stage, a dual-ported device may appear under the operating system
as two distinct devices. This situation is normal; you can resolve this later by
configuring one path to the device as an alternate path. If one device is
configured as two devices, do not write data to this device because it can
confuse the file system.
Verification: Verify that HBAs recognize target devices by using operating system
device configuration utilities, or use SANsurfer FC HBA Manager to display target
devices found on an HBA.
To mask devices or LUNs—or if devices appear twice because you plan to
configure them later as preferred and alternate paths—do not format devices,
assign drive letters, nor save this disk configuration.
In Windows, use the computer management utility to view which target
devices are configured on which HBAs, and to view and format devices and
LUNs that are found.
In NetWare, use the Scan all LUNs and List Storage Adapters
commands to view which target devices are configured on which HBAs. You
can use the nwconfig or hdetect utility to view the devices and LUNs
found.
In Linux, open /var/log/messages to view which target devices are
configured on which HBAs. Entries are also created for each HBA
recognized by the driver. Each entry contains information about target
devices and LUNs that are found.
In Solaris, open /var/adm/messages to view which target devices are
configured on which HBAs.

Step 4: Install any RAID Filter Drivers

Some RAID subsystems (including some CLARiiON
subsystems) provide redundancy by using the subsystem to provide the same
LUNs through two separate controllers in the subsystem. These controllers
appear as unrelated target devices to HBAs and miniport drivers. They are tied
together in the driver stack through a filter driver that understands the relationship
between these target devices and can move LUNs back and forth between
controllers.
To install and verify RAID filter drivers, see your RAID subsystem installation
documentation or associated software documentation.
If you do not have any such drivers to install, skip to
