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.
[-f] lb The lb option is used to perform loopback tests on the port. WARNING: This is a DES-
TRUCTIVE 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, tachyon, plm
, crpat,orcjtpat. The
TACHYON TL and TACHYON XL2 cards support only the
plm, crpat, and
cjtpat.
options.
For TACHYON, TACHYON TL and TACHYON XL2 cards, this command performs an
internal loopback test when the
tachyon option is specified and performs an external
loopback test when one of the plm,
crpat,andcjtpat options is specified. The fibre
channel chip is programmed in either internal loopback mode (
tachyon) or external loop-
back mode (
plm, crpat,or
cjtpat) based on the parameter specified. Here plm refers
to physical link module or gigabit link module,which builds the default payload for the loop-
back frame. If the
crpat or the cjtpat option is used, then the card builds specific pay-
loads 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 specify 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 initia-
tor is aware of, are displayed. The all option is supported only by TACHYON TL,
TACHYON XL2, DUAL PORT and FC/GigE Combo cards.
get_lgn (T) This option is used to obtain detailed information maintained in the login block associated
with each N_Port that this N_Port has communicated with. The remote-N-Port-ID is a
required parameter for this option. This option is not supported 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 opera-
tion 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.
[
-f] bdr (TL/XL/QL)
The bdr 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.
