38 Troubleshooting
The Hardware Wizard scans all the INF files in the specified folder,
and selects the first INF file it finds with a device entry containing a
matching hardware ID string. It then copies the selected INF file,
renaming it to “oem<#>.if”, where the '#' is some integer, and places
the copy into the “
C:\WINNT\inf”
folder. It “compiles” the
INF
file
to a “
.PNF
” file with the same root filename, and uses its Interface
Controller model entry information to install -- or register in the
Interface Controller's case -- the newly discovered device.
The user must reboot the Host PC to complete the process, as
prompted by the Wizard.
Verifying the Interface Controller Configuration
0
If you are in doubt about the configuration or about the location of the
error, restore the Interface Controller to the factory default
configuration and configure the unit one step at a time, verifying the
functionality of the configuration after each change is made.
Verifying Mapping
0
If the Interface Controller is working in Fibre Channel-to-SCSI Initiator
mode and is using Indexed or SCC mapping, try changing to Auto-
assigned mapping.
Verifying Devices
0
Connecting the SCSI target devices directly to a SCSI interface (for
example, a host SCSI bus) to verify that the devices are functional
is
recommended
.
Verifying the Host Configuration
0
In some cases, the Fibre Channel HBA or host device driver may not be
working properly. Check the configuration of these elements.
It may be useful to check the release notes for the device driver to see if
there are any specific issues or a required configuration. It may also be
useful to ensure that the current version of the HBA driver is being
used.
Older applications can have expectations about what constitutes a
valid SCSI ID, and thus may not correctly handle certain mappings.
This is not an issue for the operating system or most applications.
Caution:
Restoring factory defaults overwrites user
configurations. In the Serial/Telnet interface, use the
save configuration option before resetting factory
defaults to allow recovery of user configuration.
