This option requires one parameter: plm,
crpat,orcjtpat. Here, plm refers to phy-
sical link module or gigabit link module, which builds the default payload for the loop-
back frame. If either
crpat or 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 specifiy whether the loopback should be external or inter-
nal, 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 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.
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 DES-
TRUCTIVE 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.
clear_stat (TL/XL/QL)
This option is used to clear the statistics maintained by the driver. This option is sup-
ported only by TACHYON TL, TACHYON XL2, DUAL PORT and FC/GigE COMBO
cards.
nsstat (TL/XL/QL)
This option is used to obtain detailed nameserver statistics maintained by the driver.
This option is supported only by TACHYON TL, TACHYON XL2, DUAL PORT and
FC/GigE Combo cards .
clear_nsstat (TL/XL/QL)
This option is used to clear the nameserver statistics maintained by the driver. This
