get local

get fabric

get remote {all|remote-N-Port-ID

}

This option is used to obtain Fibre Channel login parameters of either the

local port,

the

fabric port, or a remote port. The Fibre Channel HBAs 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.

[

-f] reset This option is used to reset the HBA (or a single FC port in case of multi-port HBAs).

WARNING: This is a DESTRUCTIVE test. The reset operation will result in aborting

communication to all nodes till the process is completed.

The

-f option can be used to suppress the warning message displayed by the Fibre

Channel driver utility.

[

-f] bdr target-device_file

This option is used to issue a Bus Device Reset to device.

WARNING: This is a DESTRUCTIVE test.

The

-f option can be used to suppress the warning message displayed by the Fibre

Channel driver utility.

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 [-s] 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. Generally, the link statistics for the HBA port is displayed.

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 {all|remote-N-Port-ID

}

This 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. Along with the statistics for

each N_Port, it also displays the loop_id (in Private Loop) and the nport_id (in Fabric).

clear_devstat {all|remote-N-Port-ID}

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.

replace_dsk

OBSOLETED. Starting with HP-UX 11i Version 3, this option is no longer supported.

On releases prior to HP-UX 11i Version 3, the Fibre Channel Tachyon TL, Tachyon TL2

and FCD drivers implemented an authentication mechanism to protect against accidental

data corruption in case of the replacement of devices. This mechanism prevented I/O

transfer when the target port Worldwide name (WWN) changed for the same remote N-

Port-Id. The

replace_dsk option was used to validate replacement of the disk by asso-

ciating the new WWN with the remote N-Port-Id. Starting with HP-UX 11i Version 3,

this authentication mechanism has been replaced by an enhanced mechanism based on

the LUN Worldwide Identiﬁer (WWID). Instead of the fcmsutil replace_dsk com-

mand, use the scsimgr commands, replace_wwid and replace_leg_dsf, to vali-

date the replacement of devices. See the scsimgr (1M) manpage for more information.
