DESCRIPTION [Toc] [Back]
The fcmsutil command is a diagnostic tool to be used for TACHYON TL
A5158A, A6684A, A6685A, TACHYON XL2 A6795A, DUAL PORT A6826A and
FC/GigE Combo A9782A/A9784A Fibre Channel Host Bus Adapters. This
command provides the ability to perform Fibre Channel Test and Echo
functionality, read the card's registers, etc. This command requires
the use of a device file to indicate the interface over which the
requested command needs to be performed.
The options that are available only for TACHYON TL A5158A, A6684A,
A6685A HBAs are indicated by "TL" in the description for the option.
TACHYON XL2 A6795A HBA only options are indicated by "XL".
DUAL PORT A6826A and FC/GigE A9782A/A9784A Combo HBA only options are
indicated by "QL".
All other options (which do not have the "TL" or "XL" or "QL"
indication) are supported (completely or partially) by all the above
HBAs.
fcmsutil can be used only by users who have an effective user ID of 0.
Some of the options require detailed knowledge of the device specific
adapter.

Options [Toc] [Back]
fcmsutil recognizes the following options as indicated in SYNOPSIS.
All keywords are case-insensitive and are position dependent.
device_file Can be used alone or with other options.
When used without any options it provides information
such as the N_Port ID, Node World Wide Name and Port
World Wide Name, Topology of the Fabric, the Speed of
the Link, the Hard Physical Address of the Card, the
Driver State, the number of Active Outbound Exchanges
and number of Active Logins.
For TACHYON TL and TACHYON XL2 cards, it provides
information such as the N_port_ID, Node World Wide Name
and Port World Wide Name, Topology, Vendor ID, the Chip
Revision Number, Device ID, the Driver State, Hardware
path, number of Assisted IOs and number of Active
Logins, Presence of Dino bus bridge, Maximum frame size
and Driver version.
For DUAL PORT and FC/GigE Combo cards, it provides
information such as the N_port_ID, Node World Wide Name
and Port World Wide Name of HBA and the the switch when
applicable, Topology, Vendor ID, Device ID, ISP Code
revision, PCI Bus mode, the Driver State, Hardware
path, Maximum frame size, Firmware Dump information and
Driver version.
As per the FC protocol, Node WWN will be numerically
one more than the Port WWN. For TACHYON XL2 card
(A6795A), DUAL PORT(A6826A), and FC/GigE Combo Cards
(A9782A/A9784A) negotiated Link Speed is also indicated
in addition to the above information.
The following topologies are defined:
UNKNOWN. The host bus adapter is not attached to a
loop/loopback hood or has connection problems and could
not come up in a valid topology.
PRIVATE_LOOP. The host bus adapter is attached to a
loop/loopback hood.
PUBLIC_LOOP. Supported by TACHYON TL, TACHYON XL2,
DUAL PORT and FC/GigE Combo cards. The host adapter is
attached to a loop connected to a Fibre Channel switch.
IN_PTTOPT_NPORT/PTTOPT_NPORT. The host bus adapter has
come up in a point to point topology. This topology
can be an error if the card was expected to come up in
Hewlett-Packard Company - 3 - HP-UX 11i Version 2: Sep 2004
fcmsutil(1M) fcmsutil(1M)
loop topology. Not legal in most cases.
PTTOPT_FABRIC. The host bus adapter has come up in a
point to point topology when connected through a Fibre
Channel switch. This topology can be an error if the
card was expected to come up in loop topology. Not
legal in most cases.
The following are the driver states:
LOOPBACK_STATE. The host bus adapter is in the loop
back test phase.
OFFLINE/DISABLED. The host bus adapter is not
participating on the loop. In case of DUAL PORT and
FC/GigE Combo Cards, this state is the result of user
disabling the card through the 'disable' option in
fcmsutil.
READY/ONLINE. The driver is up and functional.
RESETTING. The host bus adapter is being reset.
SUSPENDED. The driver has been suspended by the user.
This state is applicable only to DUAL PORT & FC/GigE
Combo cards.
All other states are only "transient" and should not
continue for long. If the "transient" state persists,
there might be a problem in the hardware connectivity
or configuration.
The following link speeds are defined:
UNINITIALIZED. The host bus adapter not could converge
to a common link speed or adapter is not connected.
1Gb. The link is online and the operating speed is 1
Gigabits per second.
2Gb. The link is online and the operating speed is 2
Gigabits per second.
vpd (XL/QL) This option is used to display "Vital Product Data"
information of the HBA. It includes information such
as the Product description, Part number, Engineering
Date Code, Part serial number, etc. This option is
supported only by TACHYON XL2 A6795A, DUAL PORT A6826A
and FC/GigE Combo A9782A/A9784A cards.

echo This option is used to send an ECHO ELS frame on the
wire. It requires two parameters, the remote-N-Port-ID
and data-size (size of packet to send). An optional
third argument (count) can be specified for the number
of echo packets to be sent. If the count option is not
specified, one packet will be sent. The count option is
supported only by TACHYON TL, TACHYON XL2, DUAL PORT &
FC/GigE Combo cards.
Fibre Channel Echo packet(s) of the specified size is
sent to the remote node. The command completes
successfully when an echo response is received from the
remote node and matches the data sent, for all packets
sent. The command times out if a response is not
received in twice RA_TOV time. Echo packets cannot be
sent in a PUBLIC_LOOP topology.
Note: Packet size specified must be a multiple of 4.
rls This option is used to send an RLS (Request Link
Status) ELS frame on the wire. It requires one
parameter, the remote-N-Port-ID. The ELS is sent to
this remote-N-Port-ID and the response data is
displayed.
test This option is used to send a TEST ELS on the wire. It
requires two parameters, the remote-N-Port-ID and
data-size (size of packet to send). An optional third
argument (count) can be specified for the number of
echo packets to be sent. If the count option is not
specified, one packet will be sent. The count option is
supported only by TACHYON TL, TACHYON XL2, DUAL PORT
and FC/GigE COMBO cards.
The command completes successfully and immediately on
sending all the test packets.
Note: Packet size specified must be a multiple of 4.
read This option is used to read from HBA's internal
registers. It requires one parameter, the offset of the
register to read from. The offset can be specified in
either hex or in decimal format. The offset specified
is an offset from the base of the Memory Map. The user
of this command is therefore expected to have internal
knowledge of the chip. Reading from the Tachyon frame
manager status register (0x01c8) is restricted.
An optional second argument (pci) can be specified for
TACHYON TL, TACHYON XL2, DUAL PORT and FC/GigE Combo
cards, to read from the PCI config space. If no second
Hewlett-Packard Company - 5 - HP-UX 11i Version 2: Sep 2004
fcmsutil(1M) fcmsutil(1M)
argument is specified, it reads from the chip register
space.
write This option is used to write into HBA's registers. It
requires two parameters, the offset of the register to
write to and the value to be written.
An optional third argument (pci) can be specified for
TACHYON TL, TACHYON XL2, DUAL PORT and FC/GigE Combo
cards, to write into the PCI config space. If no third
argument is specified, it writes into the chip register
space.
lb
-f lb This option is used to perform loopback tests on the
port. WARNING: This is a DESTRUCTIVE test, and DATA
LOSS during the execution of this test may occur. The
-f option can be used to suppress the warning message
displayed by TACHYON TL, TACHYON XL2, DUAL PORT and
FC/GigE Combo cards.
This option requires one parameter: plm, crpat, or
cjtpat. Here, plm refers to physical link module or
gigabit link module, which builds the default payload
for the loopback frame. If either crpat or cjtpat
option is used, then the card builds specific payloads
based on the recommendations in Fibre Channel --
Methodologies for Jitter Specifications. These
patterns are designed to generate bit patterns which
stress the transmit and receive channels of the card.
The self test then involves sending a packet and
receiving back the packet within the adapter and
checking its integrity. Since this self test is at the
adapter level, no packet goes on the fibre link.
The DUAL PORT and FC/GigE Combo cards need two
parameters. The first parameter should be either ext or
int to specifiy whether the loopback should be external
or internal, respectively. The second parameter
specifies the loopback pattern. Only crpat and cjtpat
options are supported for these cards. Frames are
looped back at the single bit interface in the Internal
loopback mode. For external loopback, frames are sent
out and received from the wire. External loopback mode
is supported only in Loop topology. NOTE: In the
internal loopback mode, frames are also sent out on the
wire even though they are internally looped back at the
1 Bit interface. The receiver however is turned off
during this operation. Therefore, it is not safe to
run Internal loopback tests when the fiber is connected
to a Switch or Hub, as the transmitted loopback frames

can disrupt operation on the SAN.
An optional third argument (count) can be specified for
the number of loopback packets to be sent. If the count
option is not specified, one packet will be sent. The
count option is supported only by TACHYON TL, TACHYON
XL2, DUAL PORT, and FC/GigE COMBO cards.
get This option is used to obtain Fibre Channel login
parameters of either the local port, the fabric port,
or of a remote port. TACHYON TL, TACHYON XL2, DUAL
PORT, and FC/GigE Combo cards do not support the local
option. If the all argument is specified for the remote
option, login parameters and current states of all
N_ports that the initiator is aware of, are displayed.
The all option is supported only by TACHYON TL, TACHYON
XL2, DUAL PORT and FC/GigE Combo cards.
reset This option is used to reset the HBA (or a single FC
port in case of DUAL PORT and FC/GigE Combo cards).
WARNING: This is a DESTRUCTIVE test. The reset
operation will result in aborting communication to all
nodes till the process is completed. This option only
results in a soft reset for the TACHYON TL and TACHYON
XL2 cards and does not result in termination of
communication.
bdr (TL/XL/QL)
-f bdr (TL/XL/QL)
This option is used to issue a Bus Device Reset to
device. WARNING: This is a DESTRUCTIVE test. The -f
option can be used to suppress the warning message
displayed by TACHYON TL, TACHYON XL2, DUAL PORT and
FC/GigE Combo cards.
This option resets the target, clearing all commands,
without doing any checks. This option is supported
only by TACHYON TL, TACHYON XL2, DUAL PORT and FC/GigE
COMBO cards.
read_cr This option can be used to read all of the readable
registers on the card and format the detailed
information.
stat This option is used to obtain detailed statistics
maintained by the driver. An optional argument (-s) can
be specified for TACHYON TL and TACHYON XL2 cards, to
obtain a shortened version of the statistics maintained
by the driver.
