HP-UX Reference (11i v2 03/08) - 1M System Administration Commands A-M (vol 3)

f
fcmsutil(1M) fcmsutil(1M)
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, 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 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 can occur during
execution of this test.
-f lb The -f option can be used to suppress the warning message.
This option requires one parameter,
plm,
crpat,orcjtpat.
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.
This command performs an external loopback test when one of the
plm, crpat,andcjtpat options is specified. The fibre channel chip is programmed
into external loopback mode. Here plm refers to physical link module or gigabit link
module, which builds the default payload for the loopback frame. If the crpat or the
cjtpat option is used, then the card builds specific payloads based on the recommenda-
tions 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.
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. TACHYON TL and TACHYON XL2 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.
reset WARNING: This is a DESTRUCTIVE test. This option 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 and
TACHYON XL2 cards and does not result in termination of communication.
bdr WARNING: This is a DESTRUCTIVE test.
-f bdr The -f option can be used to suppress the warning message displayed.
This option resets the target, clearing all commands, without doing any checks.
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, 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.
nsstat This option is used to obtain detailed nameserver statistics maintained by the driver.
clear_nsstat
This option is used to clear the nameserver statistics maintained by the driver.
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.
