FibreQuik - Fibre Channel Adapter User Guide
Description
The Cambex FibreQuik™Fibre Channel host bus adapters
provide attachment of Fibre Channel devices to PCI or Micro
Channel based servers. They support the SCSI-FCP protocol.
When used with the Cambex Alternate Channel Failover
software, two adapters in a system provide greater throughput
and total protection from failure of a fibre channel loop.

AIX Driver Installation
Command line driver installation
The name and revision level of a driver may be examined by
issuing the command (as root):
installp -ld <device>
where <device> is replaced by /dev/fd0 for the floppy drive,
/mnt/AIX/PC1000.image for a CD-ROM mounted at /mnt or
the name of a driver image file on the hard disk, typically
MC1000.image for Micro Channel systems or PC1000.image
for PCI systems. Example output would be:
Option Name Level I/U Q Content
==================================================
PC1000.driver.obj 01.05.22.00 I N usr
Cambex Fibre Channel Adapter Driver
Before installing a new version of the driver, delete the previous
version of the driver. Note that any filesystems, volume groups
and SCSI devices must be removed before removing the driver.
Be sure to have a complete backup of all data before attempting
to update the driver. The command to remove the driver is:
installp -u <name>.driver.obj
where name is one of MC1000, PC1000, q2100, q2100m,
q2200 or q2200m depending on the type of card and previous
driver version.
The new driver may be installed on the system with the
command:
installp -acd <device> all
- 3 -
FibreQuik - Fibre Channel Adapter User Guide
where <device> is as described above.
example:
installp -acd /dev/cd0 all
After installing the driver, see the README file for additional
information

SMIT Driver Installation
The smit path is
Software Installation and Maintenance
Install and Update Software
Install and Update Software by Package Name
For the menu item " INPUT device / directory" use /dev/cd0,
or the directory where the image file is located. A list should
pop up with the name of the driver. Select it and press enter.
Hardware Installation
Power down the system and install the adapter in a free slot.
The PCI card will work in either 32 or 64-bit PCI card slots.
Make sure that airflow is not blocked by cables. Observe
proper static precautions. Detailed procedures for opening the
case may be found in the Operator Guide for the specific
RS/6000 model.
When using copper cable, it is extremely important that the
building wiring present a low impedance ground path to the
frame of the device and the host with which it will
communicate. Additional ground wiring may be added between
the unit and the host to ensure that no electrical noise is
impressed on the interconnecting data cables. Noise due to
copiers or large machinery sharing the electrical circuits is a
common cause of signal integrity problems.

AIX Configuration
During power-up initialization, AIX will find and configure the
new adapter(s) and any supported devices using the driver's
configuration method. Devices are assigned a SCSI ID as they
are discovered starting with 0. SCSI ID is not related to loop
ID or to SCSI ID assignment on other hosts.
Configuration may also be run from the command line:
cfgmgr
Once disks have been configured, the standard smit utilities
may be used to build volume groups, logical volumes and file
systems. See the AIX System Management Guide for a detailed
explanation.
Find out the names of the installed adapters with the command:
lsdev -Cc adapter
In a loop, the ID of each device must be unique. For disk
drives, the ID is typically set by switches on the drive
enclosure. The adapter ID is soft assigned and may be
examined after it is participating with the mbtest command. If
the adapter name found by the lsdev command is scsi1, the
command would be:
/usr/lpp/cbxfc/mbtest scsi1 id
The requested ID may be changed in the database to any non-
conflicting value in the range 0 to 126 with the command:
chdev -l scsi1 -a id=6 -P

Persistent Bindings
Persistent Bindings is the term used to indicate the mapping of
SCSI ID to FC Worldwide Name (WWN). By keeping a
persistent binding, the loop ID or port ID of a device may
change and the device will still be properly addressed.
In the Cambex AIX driver, persistent binding is automatic. At
configuration time, all devices that are found are automatically
assigned to a SCSI ID and a persistent binding is created.
Persistent bindings are by port name and are kept in the ODM
database. They are preserved and restored at reboot for all FC
devices.
To display the SCSI ID to WWN mapping for all adapters and
devices, issue the command:
/usr/lpp/cbxfc/fctest
SMIT commands
The commands available in SMIT are in the devices menu
under Cambex Fibre Channel Adapter:
List all Cambex FC adapters
This provides the name and location of each adapter.
Change / Show Characteristics of an Adapter
Allows the user to display and modify attributes. Changeable
attributes (with default values in parentheses) are described
below. The defaults are chosen to give best performance in
most applications..
Attributes used only in loop mode
Adapter fibre channel loop ID (0)
- 6 -
FibreQuik - Fibre Channel Adapter User Guide
Login after LIP (yes)
Full duplex in loop mode (no)
Attributes used to limit data rate or resources used
Execution throttle (256 simultaneous I/O)
IOCB allocation (256)
DMA window size (PCI only, 64MB)
Max frame size (1024) or 512, 2048.
Fibre channel rate in GHz for PC2000 (auto)
SCSI device types to exclude (none)
Topology list (P2P_LOOP)
Error recovery
Delay after bus reset or other error (10 seconds)
Maximum command timeout (300) in seconds
Disconnect time before logging an error (60 sec)
Generate Error Report
Accesses the AIX error logging facility.
Trace Cambex FC Adapters
Runs the AIX trace facility, looking only for the entries specific
to the adapter driver. The trace facility must be installed from
fileset bos.sysmgt.trace
Change / Show Device Status
Shows status of alternate paths to the device and allows manual
unfail of paths. (Available with Dynamic Path Failover driver
only).
Configure Path / Show Path Status
Shows path status and allows unconfigured paths to be added.
(Available with Dynamic Path Failover driver only).
AIX Troubleshooting
Use the errpt command to identify the cause of failure. The
lsdev command will provide the location of the component. For
- 7 -
FibreQuik - Fibre Channel Adapter User Guide
example, if errpt identifies a loose cable on device cda1, lsdev
will give an address similar to:
cda1 Available 00-02-01-3,0 Cambex SCSI...
Which indicates that the adapter is in location 00-02, and the
drive is at SCSI ID 3, LUN 0.
Checklist for driver and HBA installation
The following commands may be used to isolate problems
during installation of the fibre channel driver and card. Type
the command shown in bold and verify the output.
whoami must be root
uname -a must give 5 fields:
'AIX'
hostname where card is installed
1 or higher as minor rev of AIX
4 as version of AIX
serial number of host
lslpp -l PC1000.driver.obj must give:
Fileset Path: /usr/lib/objrepos PC1000.driver.obj
Level 01.05.00.00 (or greater)
State Committed
Description Cambex Fibre Channel Adapter Driver
lsdev -Cc adapter should print a line for each card:
scsi<x> <x> is a unique number for each SCSI card
Available <SS-SS> <S> is the location in the machine where
the card is installed
Check that the number of SCSI cards and their slots are correct
If 'Available' then card and driver are installed.
If 'Defined' or not listed then card was not found.
