5.5.4 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 command Get syntax: get FcConnMode

FcDataRate

Specifies the Fibre Channel data rate at which the Diamond will operate. Applies to both Host Interface Cards.

Default: auto

Set syntax: set FcDataRate [1gb 2gb auto]

Get syntax: get FcDataRate

Requires a SaveConfiguration command

FcFairArb

Enabling this feature causes the Diamond Storage Array to follow the arbitration fairness rules on the FC-AL. Applies to both Host Interface Cards.

Default: enabled, enabling arbitration fairness

Set syntax: set FcFairArb [enabled disabled]

Get syntax: get FcFairArb

Requires a SaveConfiguration command

FcFrameLength

Sets the frame length of a command. If not specified in the set command, current frame length is displayed. Applies to both Host Interface Cards.

Default: 2048

Set syntax: set FcFrameLength [512 1024 2048]

Get syntax: get FcFrameLength Requires a SaveConfiguration command

FcFullDuplex

Enable to allow full duplex Fibre Channel communication between the Diamond Storage Array and host devices. Disable FcFullDuplex causes half duplex mode.Applies to both Host Interface Cards.

Default: enabled

Set syntax: set FcFullDuplex [enabled disabled] Requires a SaveConfiguration command

Get syntax: get FcFullDuplex

FcHard

If hard addresses are enabled, the Diamond Storage Array will try 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 Host Interface Cards.

Default: disabled

Set syntax: set FcHard [enabled disabled]

Get syntax: get FcHard

Requires a SaveConfiguration command

FcHardAddress

This hexadecimal value represents the address the Diamond Storage Array will try 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]]

Get syntax: get FcHardAddress [fp] Requires a SaveConfiguration command

FcNodeName

Returns the Fibre Channel node name stored in NVRAM for this Fibre Channel port: the same as the World Wide Name for port 0.

Get syntax: get FcNodeName
