to firmware hang or to an irrecoverable error in the firmware or hardware. The dump files
will be saved in the /tmp directory. The Firmware dump will be stored in a file named
fcdfw_date-timestamp.
dmp and the driver dump will be saved in a file named
fcddrv_date-timestamp.
dmp. These dumps should be sent to HP for further analysis of
the problem. This option is supported only by FCD Driver-Based and FC/GigE Combo
cards.
NOTE: The driver does not save any new dumps, until the previously saved dump is
retrieved with this option. The availability of a saved dump can be checked by running
fcmsutil FCD_device_file.
dump_nvram (FCD)
This option is used to display the contents of NVRAM on the adapter. It is supported only
by FCD Driver-Based and FC/GigE Combo cards.
rom_fw_update
(FCD)
This option is used to update the ROM firmware stored in card’s FLASH ROM. WARN-
ING: This is a DESTRUCTIVE operation. Using this option may result in failure
of current I/O requests. This option requires the name of a binary image file that con-
tains the updated firmware. This operation should only be performed by qualified person-
nel. Failure to successfully complete the firmware update may result in adapter and/or sys-
tem failure in case the boot disks are accessed through this card.
This option is supported only by FCD Driver-Based and FC/GigE Combo cards.
efi_drv_update (FCD)
This option is used to update the EFI driver stored in card’s FLASH ROM. WARNING:
This is a DESTRUCTIVE operation. Using this option may result in failure of
current IO requests. This option requires the name of a binary image file that contains
the EFI driver. This operation should only be performed by qualified personnel. Failure to
successfully complete the EFI driver update may result in adapter and/or system boot up
failure if the boot disks are accessed through this card.
This option is supported only by FCD Driver-Based and FC/GigE Combo cards.
[
-f] set_int_delay
(FCD)
This option is used to set the interrupt delay mode and value, or to turn off interrupt delay.
Settings made using this option are not persistent across reboots. WARNING: This is a
DESTRUCTIVE operation and will abort communication to all target devices
until the process is completed. The
-f option can be used to suppress the warning
message.
The off option turns off interrupt delay.
The interrupt delay mode, also known as Zero Interrupt Operation (ZIO) mode, is set using
the -z option. There are two interrupt delay modes available: 5 and 6. Mode 5 delays
every interrupt by the interrupt delay period. Mode 6 delays an interrupt unless there are
no active I/Os in the HBA port, in which case the interrupt is generated immediately. If
the -z option is not specified, then mode 6 is used by default. The interrupt delay period is
calculated from the interrupt delay value using the formula:
value * 200 microseconds
get_int_delay
(FCD)
This option displays the current interrupt delay settings for the HBA port.
EXAMPLES
Print the remote port parameters using the get remote option if the driver is idle. /dev/td1 is the
device file and /dev/rdsk/c27t0d0 is the respective raw disk file.
fcmsutil /dev/td1 get remote 0x98
Print a short listing of the statistics maintained by the driver, with /dev/td1 as the device file.
fcmsutil /dev/td1 stat -s
Send 5 echo packets of 200 bytes each to a remote N_Port with loop_id 4, with /dev/td1 as the device
file.
