4.5.3 Fibre Channel Configuration Commands

The Fibre Channel ports are configured with default settings but may be customized to your
specifications using the CLI commands in this section.

FcConnMode

Specifies the Fibre Channel topology for the Diamond
Storage Array. Options are loop only (loop), point-to-
point only (ptp), loop preferred (loop-ptp) or point-to-
point preferred (ptp-loop). Refer to Connecting a Fibre
Channel Array on page 11 for more information on Fibre
Channel topology. Applies to both Host Interface Cards
Default: loop
Set syntax: set FcConnMode [loop | ptp| loop-ptp| ptp-
loop]
Requires a SaveConfiguration Restart command
Get syntax: get FcConnMode

FcDataRate

Specifies the Fibre Channel data rate at which the
Diamond operates. Applies to both Host Interface Cards
Default: auto
Set syntax: set FcDataRate [1gb | 2gb | auto]
Requires a SaveConfiguration Restart command
Get syntax: get FcDataRate

FcFairArb

Enabling this feature causes the Diamond Storage Array
to follow the arbitration fairness rules on the FC-AL.
Applies to both Fibre Channel ports
Default: enabled, enabling arbitration fairness
Set syntax: set FcFairArb [enabled | disabled]
Requires a SaveConfiguration Restart command
Get syntax: get FcFairArb

FcFrameLength

Sets the frame length of a command. If not specified in
the set command, current frame length is displayed.
Applies to both Fibre Channel ports
Default: 2048
Set syntax: set FcFrameLength [512 | 1024 | 2048]
Requires a SaveConfiguration Restart command
Get syntax: get FcFrameLength

FcFullDuplex

Enable to allow full duplex Fibre Channel
communication between the Diamond Storage Array and
35
ATTO Technology Inc. Diamond Storage Array Installation and Operation Manual
host devices. Disable FcFullDuplex causes half duplex
mode. Applies to both Fibre Channel ports
Default: enabled
Set syntax: set FcFullDuplex [enabled | disabled]
Requires a SaveConfiguration Restart command
Get syntax: get FcFullDuplex

FcHard

If hard addresses are enabled, the Diamond Storage Array
tries to use its internal hard address as its address on the
loop. Under soft addressing, the Diamond Storage Array
loop address is assigned during loop initialization. Use
FcHardAddress (described below) if you enable hard
addressing. Applies to both Fibre Channel ports
Default: disabled
Set syntax: set FcHard [enabled | disabled]
Requires a SaveConfiguration Restart command
Get syntax: get FcHard

FcHardAddress

This hexadecimal value represents the address the
Diamond Storage Array tries to use if hard addressing is
enabled. When an optional address is not present, the
current value is displayed. Each port has individual hard
address value
Default: 0x03 for port 0, 0x04 for port 1
Set syntax: set FcHardAddress [fp |[address]]
Requires a SaveConfiguration Restart command
Get syntax: get FcHardAddress [fp]

FcPortInfo

Retrieves information about the current state of each
Fibre Channel port. The status field indicates 'disabled'
when a port has been internally disabled.
Immediate command: FcPortInfo

FcPortList

Lists the status of all available Fibre Channel ports.
Immediate command: FcPortList
