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, 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. As per the FC protocol, Node WWN will be
numerically one more than the Port WWN. For TACHYON XL2 card (A6795A), in addi-
tion to the above, Negotiated Link Speed is also indicated.
The following topologies are defined:
UNKNOWN. The host bus adapter is not attached to a loop/loopback hood or has connec-
tion 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 and TACHYON XL2 cards. The host
adapter is attached to a loop connected to a Fibre Channel switch.
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. The host bus adapter is not participating on the loop.
ONLINE. The driver is up and functional.
RESETTING. The host bus adapter 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.
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 Gigabytes.
2Gb. The link is online and the operating speed is 2 Gigabytes.
vpd (XL) This option gives the "Vital Product Data" of the HBA. The
vpd option provides informa-
tion such as the Product description, Part number, Engineering Date Code, Part serial
number, etc. This option is supported only by TACHYON XL2 A6795A cards.
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.
Fibre Channel Echo packet(s) of the specified size is sent to the remote node. The com-
mand 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 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.
A Fibre Channel Test packet of the specified size is sent to the remote node. The com-
mand completes successfully and immediately on sending all the test packets.
Note: Packet size specified must be a multiple of 4.
