- 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 the TACHYON TL A5158A card, it provides information such as the N_port_ID,
Node World Wide Name and Port World Wide Name, Topology, Vendor ID,
Device ID, the Driver State, number of Assisted IOs and number of Active
Logins. As per the protocol, Node WWN will be one more than the Port WWN.
The following topologies are defined:
UNKNOWN.
The host adaptor card is not attached to a loop/loopback hood or has
connection problems and could not come up in a valid topology.
IN_LOOP.
The card is attached to a loop/loopback hood.
IN_LOOP_FL.
Not supported.
IN_PTTOPT_NPORT.
The card has come up in a point to point topology. This topology can be
an error if the the card was expected to come up in loop topology. Not
legal in most cases.
IN_PTOPT_FABRIC.
The card has come up in a point to point topology when connected through
a Fibre Channel switch. This topology can be an error if the the card was
expected to come up in loop topology. Not legal in most cases.
IN_PTTOPT
This is a transition topology. Not legal in most cases.
The following are the driver states:
DEAD.
The driver couldn't come up due to some problem. Check the connectivity with
the loop/loopback hood.
LOOPBACK_STATE.
The host bus adaptor is in the loop back test phase.
OFFLINE.
The host bus adaptor card is not participating on the loop.
READY/ONLINE.
The driver is up and functional.
RESETTING.
The host bus adaptor card is being reset.
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.
- echo
This option 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 the TACHYON TL A5158A card.
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.
Note:
Packet size specified must be a multiple of 4.
- rls
This option requires one parameter, the
remote-N-Port-ID.
A Fibre Channel Request Link Status (RLS) ELS is sent to the
remote-N-Port-ID
and the response data is displayed.
- test
This option 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 the TACHYON TL A5158A card.
A Fibre Channel Test packet of the specified size is sent to the remote node.
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 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 the TACHYON TL A5158A card, to
read from the PCI config space. If no second argument is specified, it
reads from the chip register space.
- write
This option 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 the TACHYON TL A5158A card, to
write into the PCI config space. If no third argument is specified, it writes
into the chip register space.
- lb
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 the TACHYON TL A5158A card.
This option requires one parameter,
tachyon
or
plm.
The TACHYON TL A5158A card supports only
the
plm
option. 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 the TACHYON TL A5158A card.
This command performs an internal loopback test when the
tachyon
option is specified and performs an external loopback test when
plm
option is specified. The fibre channel chip is programmed in either internal
loopback mode
(tachyon)
or external loopback mode
(plm)
based on the parameter
specified. Here
plm
refers to physical link module or gigabit link module. 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.
- get
The
get
option is used to obtain Fibre Channel login parameters of either the
local
port, the
fabric
port or of a
remote
port. The TACHYON TL A5158A card supports only the
remote
option.
- get_lgn
The
get_lgn
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 the
TACHYON TL A5158A card.
- reset
resets the fibre channel card. This is a destructive test and
communication to all nodes will be terminated till the reset process
is completed.
This option only results in a soft reset for the TACHYON TL A5158A
card and does not result in termination of communication.
- bdr
WARNING: This is a DESTRUCTIVE test. The
-f
option can be used to suppress
the warning message displayed by the TACHYON TL A5158A card.
This option resets the target, clearing all commands, without doing any checks.
This option is supported only by the TACHYON TL A5158A card.
- read_cr
This option can be used to read all of the readable registers on the card and
format the detailed information.
- lgninfo_all
This option is used to obtain a comprehensive list of nodes to which a
successful login has been established.
This option is not supported by the TACHYON TL A5158A card.
- stat
This option is used to obtain detailed statistics maintained by the driver. An
optional argument
(-s)
can be specified for the TACHYON TL A5158A card, to obtain
a shortened version of the statistics maintained by the driver.
- clear_stat
This option is used to clear the statistics maintained by the driver.
This option is supported only by the TACHYON TL A5158A card.
- devstat
The
devstat
option is used to obtain detailed statistics associated with each
N_Port that this N_Port has communicated with.
If the
remote-N-Port-ID
is specified, then the statistics associated with that
N_Port are displayed. If the
all
option is specified, statistics associated
with all N_ports that the initiator has been able to communicate with, are
displayed.
This option is supported only by the TACHYON TL A5158A card.
- clear_devstat
This option is used to clear the statistics associated with a target.
If the
remote-N-Port-ID
is specified, then the statistics associated with
that N_port are cleared. If the
all
option is specified, statistics
associated with all valid N_Port_IDs are cleared.
This option is supported only by the TACHYON TL A5158A card.
- replace_dsk
This option is used to specify that no authentication should be performed
the next time we communicate with the device. This option is to be used by
system administrators for replacing a disk, with another (with the same
N_Port_ID). Note that this is not required, if the new disk acquires a new
N_Port_ID.
This option is supported only by the TACHYON TL A5158A card.
- disable
WARNING: This is a DESTRUCTIVE test and communication to all nodes
will be terminated. The
-f
option can be used to suppress the warning
message displayed by the TACHYON TL A5158A card.
This option is used to disable a card, typically because of a hardware
problem which cannot be resolved and is interfering with system performance.
- enable
This option is used to enable a card, typically when a previous
hardware problem has been resolved.
