fcPing Sends a Fibre Channel Extended Link Service (ELS) ECHO request to a pair of ports. Synopsis fcPing [ -hbq ] [ -n frames ] [ -l length ] [ -i wait ] [ -p pattern ] source destination Availability all users Description Use this command to perform a zoning check between the source and destination. In addition, two Fibre Channel ELS requests are generated. The first ELS request is from the domain controller to the source port identifier. The second ELS request is from the domain controller to the destination port identifiers. The ELS ECHO request elicits an ELS ECHO response from a port identifier in the fabric and is useful for validating link connectivity. The source and destination port identifiers can be specified as 24-bit Fibre Channel port identifiers, port world wide names, or node world wide names. The two port identifiers are then used to determine if they are zoned together. The ELS ECHO requests comprise a 24-byte Fibre Channel frame header, a 4-byte ELS request header, an 8-byte timestamp from gettimeofday, and an arbitrary number of bytes (as specified by -l length) to fill out the request frame. The source identifier in the ELS ECHO request is the domain controller and the destination identifier is either source or destination. The echo ELS might not be supported on all devices. In such cases, the response could be either an ELS reject or a request timeout. By default, fcPing sends five ELS ECHO requests to each port. NOTE: When a device does not respond to the ELS request, further debugging is necessary to understand if this is due to the device not supporting this ELS request. The user should not assume that the device is not FC-connected. Operands This command has the following optional operands: -n frames -l length -h -i wait Specifies the number of ELS ECHO requests to send. Specifies requests containing length bytes of data. The default is 0 bytes of data. Without data, the Fibre Channel ECHO request frame size is 12 total bytes. This is a combination of four bytes from the ECHO request header and eight bytes from the timestamp. The maximum allowed value is 2,036 bytes. The length must be word aligned. Causes the program to display the proper command line usage syntax information and then terminate. Specifies the interval, in seconds, between successive ELS ECHO requests. The default is 0 seconds. 210 Fabric OS commands

Description

Use this command to perform a zoning check between the

source

and

destination

. In addition, two

Fibre Channel ELS requests are generated. The first ELS request is from the domain controller to the

source

port identifier. The second

ELS request is from the domain controller to the

destination

port

identifiers. The ELS ECHO request elicits an ELS ECHO response from a port identifier in the fabric and is

useful for validating link connectivity.

The

source

and

destination

port identifiers can be specified as 24-bit Fibre Channel port identifiers,

port world wide names, or node world wide names. The two port identifiers are then used to determine if

they are zoned together.

The ELS ECHO requests comprise a 24-byte Fibre Channel frame header, a 4-byte ELS request header,

an 8-byte timestamp from

gettimeofday

, and an arbitrary number of bytes (as specified by

-l

length

) to fill out the request frame. The source identifier in the ELS ECHO request is the domain

controller and the destination identifier is either

source

destination

The echo ELS might not be supported on all devices. In such cases, the response could be either an ELS

reject or a request timeout.

By default,

fcPing

sends five ELS ECHO requests to each port.

NOTE:

When a device does not respond to the ELS request, further debugging is necessary to

understand if this is due to the device not

supporting

this ELS request. The user should not assume that the

device is not FC-connected.

Operands

This command has the following optional operands:

fcPing

-n

frames

Specifies the number of ELS ECHO requests to send.

-l

length

Specifies requests containing length bytes of data. The default is

0 bytes of data. Without data, the Fibre Channel ECHO request

frame size is 12 total bytes. This is a combination of four bytes

from the ECHO request header and eight bytes from the

timestamp. The maximum allowed value is 2,036 bytes.

The

length must be word aligned.

-h

Causes the program to display the proper command line usage

syntax information and then terminate.

-i

wait

Specifies the interval, in seconds, between successive ELS

ECHO requests. The default is 0 seconds.
