-f option can be used to suppress the warning message displayed by TACHYON TL,
TACHYON XL2, FCD Driver-Based and FC/GigE Combo cards.
This option requires one parameter: plm, crpat
,orcjtpat. Here, plm refers to physi-
cal 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 FCD Driver-Based and FC/GigE Combo cards need two parameters. The first parame-
ter 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, FCD Driver-Based 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, FCD Driver-Based
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, FCD Driver-Based and FC/GigE Combo cards.
[-f] reset This option is used to reset the HBA (or a single FC port in case of FCD Driver-Based and
FC/GigE Combo cards). WARNING: This is a DESTRUCTIVE test. The
-f option can
be used to suppress the warning message displayed by TACHYON TL, TACHYON XL2,
FCD Driver-Based and FC/GigE Combo cards.
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.
[
-f] bdr (TL/XL/FCD)
This option is used to issue a Bus Device Reset to device. WARNING: This is a DES-
TRUCTIVE test. The -f option can be used to suppress the warning message displayed
by TACHYON TL, TACHYON XL2, FCD Driver-Based 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, FCD Driver-Based 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 argu-
ment (-s) can be specified for TACHYON TL and TACHYON XL2 cards, to obtain a shor-
tened version of the statistics maintained by the driver.
clear_stat (TL/XL/FCD)
This option is used to clear the statistics maintained by the driver. This option is supported
only by TACHYON TL, TACHYON XL2, FCD Driver-Based and FC/GigE Combo cards.
nsstat (TL/XL/FCD)
This option is used to obtain detailed nameserver statistics maintained by the driver. This
option is supported only by TACHYON TL, TACHYON XL2, FCD Driver-Based and
