[-f] set_int_delay

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 tar-

get devices until the process is completed.

The complete syntax for this command is:

[

-f] set_int_delay

{off |[-z {5 |

6}] value }

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 inter-

rupt delay period is calculated from the interrupt delay value using the formula:

value * 200 microseconds

get_int_delay

This option displays the current interrupt delay settings for the HBA port.

sfp This option is used to display diagnostics information from the card’s optical transceiver.

It includes information from the SFF-8472 speciﬁcation such as cable lengths, current

temperature, voltage, transmit and receive power, TX bias, as well as other data.

NOTE: This option is only supported by 4Gb/s capable Fibre Channel cards.

EXAMPLES

Print the remote port parameters using the get remote option if the driver is idle. In this example,

/dev/td1 is the device ﬁle and /dev/rdsk/c27t0d0

is the respective raw disk ﬁle.

fcmsutil /dev/td1 get remote 0x98 < /dev/rdsk/c27t0d0

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.

fcmsutil /dev/td1 echo -l 4 200 5

Print a short listing of the statistics of the device whose remote-N-Port-ID is 0x02ae4 and with

/dev/td1 as the device ﬁle.

fcmsutil /dev/td1 devstat 0x02ae4

Clear the device statistics of the device whose wwn is 0x100000e002219f45 and with /dev/fcd2 as the

device ﬁle.

fcmsutil /dev/fcd2 clear_devstat -w 0x100000e002219f45

Perform a Internal loopback test, sending 1000 packets with /dev/fcd2 as the device ﬁle.

fcmsutil /dev/fcd2 lb int crpat 1000

Display diagnostics information from the HBA’s optical transceiver with /dev/fcd2 as the device ﬁle.

fcmsutil /dev/fcd2 sfp
